1. Introduction
The Town of Whitby conducted an integrated and comprehensive study for the Brooklin
area to determine land use planning and transportation needs for future growth in and
around the existing community of Brooklin. The outcome of the study is a comprehensive
Secondary Plan and Transportation Master Plan (TMP) for the Brooklin area. This
Natural Environment Report is intended to document the existing natural environment
(terrestrial and aquatic) for the Brooklin area in support of the Secondary Plan and TMP.
Information used to prepare this Natural Environment Report primarily relies on a
background information review that was initially prepared in 2014 in support of a prior
study, namely the Northwest Brooklin Bypass Environmental Assessment (EA) being
conducted at that time. The Study Area for the Northwest Brooklin Bypass EA (hereafter
referred to as the “Northwest Brooklin EA Study Area”) makes up the majority of the
Study Area for the Secondary Plan and TMP (hereafter referred as the “Brooklin TMP
Study Area”). Results of background review completed for the Northwest Brooklin EA
Study Area are presented in Section 2 of this Natural Environment Report and were
incorporated into the Brooklin Study – Transportation Master Plan (AECOM, 2017).
Natural environment assessments were completed as part of the Brooklin Study as
Background Reports and cover the Secondary Plan study area. These studies were
referenced in completing the Brooklin Study – Transportation Master Plan. These
studies include the following reports that are included on the Town of Whitby Brooklin
Study website (links provided below):

In 2017, comments were received from the Miller Planning Group regarding the
preferred road alignment for the mid-block arterial road corridor shown on Exhibit 21 of
the Brooklin Study – Transportation Master Plan (AECOM, 2017). The Mid-Block
Arterial corridor identified in both the Town of Whitby 2010 TMP, and the Brooklin
Transportation Master Plan is a preliminary solution being recommended to meet the
transportation needs of the Brooklin TMP study area. Portions of the mid-block arterial
road corridor are located south of the Northwest Brooklin EA Study Area. The Natural
Environment Report previously completed in support of the Northwest Brooklin EA
Study Area was supplemented with additional information regarding natural heritage
features that are located south of the Northwest Brooklin EA Study Area and
encompassed in the Brooklin TMP Study Area. This additional information is presented
in Section 3 of this Natural Environment Report for completeness. The purpose of
Section 3 is to provide high-level description of the natural heritage features identified
in the vicinity of the mid-block arterial road.
1.1 Study Areas
The Northwest Brooklin EA Study Area generally contains the area of Brooklin that is
bounded by Lake Ridge Road to the west, Winchester Road to the south, Townline
Road to the North and the Town of Whitby / City of Oshawa border to the east. Section
2 of this Natural Environment Report document the methods used and the natural
environment existing conditions for the Northwest Brooklin EA Study Area. For the
purposes of the Physical Environment discussed in Section 2.2, the Northwest Brooklin
EA Study Area is bounded by Lake Ridge Road to the west, Townline Road to the
north, Winchester Road to the south and west of Thickson Road. For the purposes of
the Terrestrial, Aquatic Environments and Natural Heritage Features and Functions
discussed in Sections 2.3, 2.4 and 2.5, the Northwest Brooklin EA Study Area
boundaries remain the same with the exception that the eastern boundary does not
extend east of Baldwin Street North/Thickson Road North.
The Brooklin TMP Study Area generally contains of Brooklin that is bounded by Lake
Ridge Road to the west, Taunton Road to the south, Townline Road to the North and
the Town of Whitby / City of Oshawa border to the east. Section 3 of this Natural
Environment Report documents additional information regarding natural environment
exiting conditions in the areas not previously included in the Northwest Brooklin EA
Study Area discussed in Section 2.

2.2 Physical Environment
2.2.1 Physiography
Till Plain
The majority of the central portion of the study area is dominated by the Till Plain
physiographic region, which extends from the Oak Ridges Moraine south to the former
Lake Iroquois shoreline. This region is flatter than the hilly Oak Ridges Moraine and is
predominately covered by sandy till material (CLOCA, 2006).
Lake Iroquois Beach
A small portion in the south of the study area falls within the Lake Iroquois Beach, which
is considered as part of the Lake Iroquois Sand Plains (CLOCA, 2008). Lake Iroquois
was a prehistoric glacial lake that existed approximately 13,000 years ago. The Iroquois
Beach region consists of a band of sandier beach deposits that spans west to east and
is characterized by low-lying shoreline bluffs and gravel bars with an overlay of till
material (CLOCA, 2008).
6
2.2.2 Soils and Agricultural Capability
Based on Canada Land Inventory Agricultural Capability Mapping prepared by the
MNRF, the majority of undeveloped portions of the study area consist of Class “1” soils.
This class of soil has the highest capability to support agricultural land use activities.
2.2.3 Groundwater Resources
A preliminary desktop study was carried out to characterize the existing geological and
hydrogeological conditions in the study area. As part of the desktop study, a review of
current geological mapping and existing MOE water well information was carried out to
identify sensitive resources within the study area.
Based on a review of surficial geological conditions (Exhibit 1) and associated
hydrogeological properties, areas considered more susceptible to groundwater quality
and/or quantity impacts were identified. This included an approximate hydraulic
conductivity, aquifer and recharge/discharge potential. An overall groundwater impact
rating (GIR) was calculated for comparison purposes (please refer to Table 2). As
such, surficial deposits with a high overall rating are considered to be more susceptible
to groundwater quality and/or quantity impacts than those rated with a low overall
impact rating (i.e., GIR = 5 - 9).

In addition to the above, a review of the MOE Water Well Database information
available for the study area was conducted to identify the number and type of water
wells within the study area. In general, a high number of domestic water wells are
located throughout the study area, generally observed in proximity to existing rural
residences and/or hamlets. Other water well uses are noted to be sparsely located in
various locations, including livestock, commercial, industrial and municipal. It is
understood that some well uses are not classified as part of these records and/or others
are no longer in use. A copy of the preliminary hydrogeological assessment information
is provided in Appendix C.1.
2.2.4 Source Water Protection
The study area is situated within the Central Lake Ontario (CTC) Source Protection
Area, representing the eastern component of the CTC Source Protection Region in
South-central Ontario (Exhibit 2). Within this area, policies related to a list of
prescribed activities have been established by the Credit Valley, Toronto and Region,
and Central Lake Ontario Source Protection Plan1 for the purposes of protecting
municipal drinking water sources. As part of this source water protection work, the
vulnerability of these sources to a threat presented by an activity that occurs on land
has been assessed.
1. CTC Source Protection Region, 2015: Approved Source Protection Plan: CTC Source Protection Region.

Exhibit 2: CTC Source Protection Region
The five (5) types of vulnerable areas that may have associated Source Water
Protection Policies include:
Intake Protection Zones (IPZs);
Wellhead Protection Areas (WHPAs);
DNAPL2 Threat Areas;
Significant Groundwater Recharge Areas (SGRAs); and,
Highly Vulnerable Aquifers (HVAs).
2.2.4.1 Intake Protection Zones (IPZ) and Well Head Protection Areas (WHPA)
According to the CTC Source Protection Plan, there are no surface water or associated
Intake Protection Zones (IPZs) for municipal purposes located within or near the study
area. Similarly, the Plan also does not identify the presence of any Wellhead Protection
2. DNAPL is a dense non-aqueous phase liquid. It is a liquid that is denser than water (sinks to the bottom) and is immiscible.
10
Areas (WHPAs) or groundwater takings for municipal purposes within or in close
proximity to the study area.
2.2.4.2 DNAPL Threat Areas
According to the CTC Source Protection Plan, there are no DNAPL Threat Areas
located within or in close proximity to the study area.
2.2.4.3 Significant Groundwater Recharge Areas (SGRA)
Surface water received from precipitation will percolate or infiltrate into the ground until
it reaches the groundwater table. This occurs in surficial sediments that are sufficiently
permeable to permit the movement of water through its pore spaces. Areas such as
these are known as groundwater recharge areas.
Significant Groundwater Recharge Areas (SGRA) are characterized by highly
permeable soils at surface, such as sand and/or gravel, which allows water to readily
pass from the ground surface to an aquifer. These areas are considered significant
when they aid in maintaining the water level in an aquifer that provides water for potable
means and/or supplies groundwater to a cold water ecosystem.
According to the CTC Source Protection Plan, there are SGRAs associated with
portions of coarse-textured glaciolacustrine deposits within the study area. The SGRA
are generally located southwest of Winchester Road and Ashburn Road, in southeast
portion of the study area in the vicinity of Conlin Road and Thickson Road, north of the
Community of Brooklin between Ashburn Road and Thickson Road, northwest of Heron
Road and Myrtle Road and northeast of Myrtle Road and Highway 7/12 in the vicinity of
Myrtle and Myrtle Station, as shown in Exhibit 3.
11
Exhibit 3: Significant Groundwater Recharge Areas (CTC, 2015)
2.2.4.4 Highly Vulnerable Aquifers (HVA)
A highly vulnerable aquifer (HVA) is one that is susceptible to contamination due to its
location near ground surface, or the type of material found in the ground around the
aquifer. Aquifers that are located near ground surface and have less of a barrier
between the ground surface and groundwater system below are considered to be HVA.
According to the CTC Source Protection Plan, HVA exist throughout the study area, as
shown in Exhibit 4.
12
Exhibit 4: Highly Vulnerable Aquifers (CTC, 2015)
Activities within HVAs are not considered to represent a significant threat to municipal
drinking water sources and therefore do not have associated land use or activity
policies.
13
2.3 Terrestrial Environment
2.3.1 Vegetation and Flora
The study area occurs within Ecoregion 6E (Lake Simcoe – Rideau Ecoregion). An
ecoregion is a provincial MNRF term which is defined as “an area of land within which
the response of vegetation to the features of landform follows a consistent pattern” and
is “defined by a characteristic range and pattern of climatic variables” (MNRF, 2007).
The bedrock is primarily composed of dolostone and limestone. The northern limit of
Ecoregion 6 contains extensive bare bedrock plains. Alvars and associated species are
also present on the limestone plains. Ecoregion 6E spans southward between Lake
Huron in the west to the Ottawa River in the east. The landscape is generally
characterized as flat with broad till sheets and massive moraines (i.e., the Oak Ridges
Moraine) formed as result of thick deposits glacial and post-glacial sediments in the
Late Wisconsin glacial period. Most of the Niagara Escarpment is included in the Lake
Simcoe – Rideau forming a ridge that is an exception to the surrounding flat landscape
(MNRF, 2007). Wetlands and water bodies are found on 5% and 4% of the area,
respectively. Agricultural fields, deciduous and mixed forests currently comprise 57% of
the Ecoregion. The Lake Simcoe – Rideau Ecoregion supports a rich biodiversity of
wildlife and plant species. Characteristic trees of the area include Sugar Maple (Acer
saccharum), American Beech (Fagus grandifolia), White Ash (Fraxinus americana),
Eastern Hemlock (Tsuga canadensis), White Cedar (Thuja occidentalis) and Black Ash
(Fraxinus nigra) (MNRF, 2007).
The study area is within the Great Lakes/St. Lawrence Forest Region (Rowe, 1972).
This region is mixed with coniferous and deciduous forests where tree species such as
Red Pine (Pinus resinosa), Eastern White Pine (Pinus strobus), Eastern Hemlock,
Yellow Birch (Betula allegheniensis), Maple and Oak are dominant.
Ecological Land Classification (ELC) vegetation community delineations for the
Northwest Brooklin Class EA study area were obtained from CLOCA. These ELC
community delineations were categorized mostly into the Community Series level and in
some locations to the Vegetation Type (Lee et al., 1998). The Community Series are
identified based on the type of vegetation cover or plant form present that represents
the community, i.e., open, shrub or treed vegetation cover (Lee et al., 1998). It is the
lowest level in the ELC that can be identified without field investigations (Lee et al.,
1998). The Vegetation Type is the finest level of classification and is based almost
entirely on the plant species composition present in the community (Lee et al., 1998).
14
The Community Series that occur within the study area are summarized in Table 3
below and the locations are illustrated in Exhibit 5 and Exhibit 6.

The majority of the study area is dominated by anthropogenic land uses (75%) such as
residential areas, commercial areas and agricultural lands that are of low ecological
significance. Cultural communities, which represent approximately 11% of the study
area, are regenerating habitat in the process of succeeding from meadows and thickets
to forest communities (CLOCA, 2008). Some of these cultural communities may provide
important habitat for rare species; however, the majority are dominated by non-native
and invasive plant species (CLOCA, 2008). Only 5% of the study area is covered by
forest communities which perform important environmental functions and contain habitat
for woodland species. Aquatic and wetland communities make up the remaining 10% of
the study area and include a Locally Significant Wetland.
2.3.2 Wildlife
2.3.2.1 Mammals
According to the Atlas of the Mammals of Ontario (Dobbyn, 1994), the geographic
distributions of the following mammal species of southern Ontario occur within the study
area: White-tailed Deer (Odocoileus virginianus), Coyote (Canis latrans), Red Squirrel
(Tamiasciurus hudsonicus), Eastern Gray Squirrel (Sciurus carolinensis), Eastern
Chipmunk (Tamias striatus), Meadow Vole (Microtus pennsylvanicus), Red Fox (Vulpes
vulpes), Striped Skunk (Mephitis mephitis) and Eastern Cottontail (Sylvilagus floridanus).
All of these species are common mammals and are expected to occur in the study area.
2.3.2.2 Birds
Ontario Breeding Bird Atlas (OBBA; 2001-2005) point count data was obtained from Bird
Studies Canada. A list of bird species was generated from portions of four 10 km x 10 km
squares that occupy the study area (refer to Appendix C.2 for a complete species list).
Species recorded within and/or in the vicinity of the study area include a number of birds
commonly found in southern Ontario, such as American Robin (Turdus migratorius),
American Goldfinch (Spinus tristis), Common Grackle (Quiscalus quiscula), Canada
Geese (Branta canadensis), House Sparrow (Passer domesticus), Mourning Dove
(Zenaida macroura), Song Sparrow (Melospiza melodia) and Red-winged Blackbird
(Agelaius phoenicus). Many of these birds are associated with human-modified
landscapes, such as urban or suburban areas or agricultural fields, whereas some are
typically found in woodland and forest habitats. Seven of these birds are Species At Risk
or considered rare in the province of Ontario (NHIC, 2010) and may be present within the
study area. These are discussed in greater detail in Table 4 below.

Notes:
1ESA Status: The Endangered Species Act 2007 (ESA) protects species listed as Threatened and Endangered on the Species at
Risk in Ontario (SARO) List on provincial and private land. The Minister lists species on the SARO list based on recommendations from the Committee on the Status of Species at Risk in Ontario (COSSARO), which evaluates the conservation status of species occurring in Ontario. The following are the categories of at risk:
END (Endangered) – A species facing imminent extinction or extirpation in Ontario.
THR (Threatened) – Any native species that, on the basis of the best available scientific evidence, is at risk of becoming endangered throughout all or a large portion of its Ontario range if the limiting factors are not reversed.
SC (Special Concern) – A species that may become threatened or endangered due to a combination of biological characteristics and identified threats.
NAR (Not at Risk) – A species that has been evaluated and found to be not at risk. 2 Information pertaining to Habitat Preferences was obtained from Ontario Ministry of Natural Resources, 2000. Significant Wildlife
Habitat Technical Guide. 151 pp.

2.3.2.3 Herpetofauna
According to the Ontario Herpetofaunal Summary Atlas (Oldham and Weller, 2000), the
following amphibian species are known to occur in the vicinity of the study area:
Common Mudpuppy (Necturus maculosus), Red-spotted Newt (Notophthalmus
viridescens), Northern Redback (Plethodon cinerus), American Toad (Bufo
americanus), Spring Peeper (Pseudacris crucifer), Western Chorus Frog (Pseudacris
triseriata), Gray Treefrog (Hyla versicolor), Wood Frog (Rana sylvatica), Northern
Leopard Frog (Rana pipiens), Green Frog (Rana clamitans), Mink Frog (Rana
septentrionalis) and Bullfrog (Rana catesbeiana). According to the Provincial ranking
from Natural Heritage Information Centre, most of these amphibians have a S5 ranking or
a “secure” ranking, which means that the species is common, widespread and abundant
in Ontario. The Bullfrog has a S4 ranking which means that it is “apparently secure”, and
is known as an uncommon but not a rare species. Breeding amphibians are generally
found in wooded ponds and temporary vernal pools in spring where they mate and lay
eggs in the water. As such, suitable habitat may be located within the study area for these
species.
Snakes generally hibernate in rock crevices, rock piles and abandoned foundations that
allow snakes to enter ground below the frost line. Meanwhile, turtles are found in or near
permanent water bodies such as deep rivers, large wetlands and ponds with soft mud
substrates. According to the Ontario Herpetofaunal Summary Atlas (Oldham and Weller,
2000), the following reptile species are known to occur in the vicinity of the study area:
Common Snapping Turtle (Chelydra serpentina), Midland Painted Turtle (Chrysemys
picta marginata), Eastern Garter Snake (Thamnophis sirtalis sirtalis) and Northern
Redbelly Snake (Storeria occipitomaculata). Most of these previously recorded reptiles
within the study area are common and relatively abundant in Ontario (NHIC, 2010).
However Snapping Turtle is designated as Special Concern, both nationally and
provincially. This species spends most of its life in shallow waters but nests in gravely or
sandy areas along streams and man-made structures including roads, dams and
aggregate pits (ROM & MNRF, 2010). All of these reptile species have the potential of
occurring in the study area.

2.4 Aquatic Environment
2.4.1 Lynde Creek Watershed
The study area is situated within the Lynde Creek Watershed and located entirely within
the Regional Municipality of Durham under the jurisdiction of the Central Lake Ontario
Conservation Authority (CLOCA) (CLOCA, 2006). The majority of the watershed falls
within the Town of Whitby, with lesser portions in Town of Uxbridge, Township of
Scugog, City of Pickering and Town of Ajax. Lynde Creek and its tributaries flow
approximately 326 km south towards Lake Ontario, from its headwaters in the Oak
Ridges Moraine (CLOCA, 2006; CLOCA, 2007). The Lynde Creek Watershed covers a
total drainage area of approximately 130 km2. The majority of the watershed (48%) is
used for agricultural purposes and urban areas account for an additional 22% of the
total land area (CLOCA, 2007). Most of the urban development is concentrated along
the east side of the watershed. Generally, this watershed supports moderate terrestrial
habitats with forests and wetlands covering 17% and 10% of the total land area
(CLOCA, 2007; CLOCA, 2012). The Lynde Creek Watershed also supports healthy fish
communities; however, urbanization and intensive agricultural land uses have degraded
aquatic habitats. This watershed comprises of five subwatersheds, of which the study
area only fall within four including: Lynde Main, Heber Down, Ashburn and Myrtle
Substation (CLOCA, 2006; CLOCA, 2008).
The Lynde Main subwatershed encompasses the southeast corner of the study area
and includes the majority of the Town of Brooklin (CLOCA, 2006). This subwatershed
drains an area of approximately 30 km2. The majority of the total area of this
subwatershed is dominated by agricultural and rural land use (CLOCA, 2008). Urban
land area covers 21.7 % of the total area (CLOCA, 2012).
The western half of the study area falls within the Heber Down subwatershed, which is
the largest subwatershed draining into an area of approximately 46 km2 (CLOCA, 2008).
The western portion of Brooklin is situated within this subwatershed. The headwaters of
the Heber Down subwatershed are located in the Oak Ridges Moraine and flow south
draining into the Lynde Main subwatershed.
The Ashburn subwatershed covers a drainage area of approximately 17 km2 and
extends north through the study area from between Brawley Road and Columbus Road
(CLOCA, 2008). Most of the land is used for agricultural purposes, which is dominant
south of the Oak Ridges Moraine. Other development within this subwatershed includes
light industrial, residential to recreational land use.
21
The Myrtle subwatershed is the smallest subwatershed and drains into an area of
approximately 15 km2. Agricultural lands and rural residential area dominate this
subwatershed (CLOCA, 2008). There has been little new development in this area in
recent years.
Water quality within the Lynde Creek Watershed exhibits signs of anthropogenic
impacts resulting from agricultural and urban runoff and nutrient enrichment. Previous
studies containing water quality results consistently show that water quality generally
degrades from northern rural areas to southern urban areas (CLOCA, 2006). The water
quality results from the Lynde Creek Watershed Resource Management Strategy
conducted by Gartner Lee Limited (1994) shows that water discharging from Chalk
Lake, located north of Townline Road and east of Lakeridge Road, contained the
highest recorded levels of suspended solids, fecal coliforms and temperature. High
levels of phosphorus and nitrogen as well as copper were also found throughout the
watershed (Gartner Lee Limited, 1994). Studies conducted for the Lynde Creek Aquatic
Resource Management Plan (CLOCA, 2006) used the Biological Water Quality
Monitoring Program (BioMap) to determine whether the water quality of stream
segments were impaired or unimpaired based on the benthic macro invertebrate
communities present at sampling sites. Results from this study suggest that the majority
of sampling sites within urban areas (75%) were impaired while most of the sampling
locations in natural areas (83%) were indicative of higher water quality (CLOCA, 2006).
Meanwhile, half of the sampling sites in agricultural areas were unimpaired (CLOCA,
2006). The main cause of water quality impairment in the southern portion of the
Watershed is urban pollution as a result of industrial waste, sewage waste and
untreated stormwater. Water quality in the northern section of the watershed is more
affected by nutrient loading from agricultural runoff (CLOCA, 2006). According to the
Lynde Creek Watershed Plan (CLOCA, 2012), the key conditions regarding surface
water quality include increasing trends in chloride and nitrates and a decreasing trend in
copper. Phosphorus levels in the watershed are generally below 30 g/L, which meet
the Provincial Water Quality Monitoring Network standards for streams (CLOCA, 2012).
Based on the CLOCA Watershed Report Card (2013), the surface water quality in the
Lynde Creek Watershed is considered as “fair”, given the levels of phosphorus.
2.4.2 Fish and Fish Habitat
Based on MNRF’s NRVIS mapping (2011), tributaries of Lynde Creek present within the
study area are generally characterized as coldwater streams. Historically, Lynde Creek
formerly consisted of a predominately cold-water system; however, changes in urban
22
land use resulted in the increase of water stream temperatures in some areas of the
watershed (CLOCA, 2007). In 1994, Gartner Lee Limited conducted a fisheries
assessment as part of the Lynde Creek Water Resource Management Strategy
(Gartner Lee Limited, 1994), the findings of which indicated that most of the tributaries
were classified as warm water habitats up to Colombus Road in the Main
Subwatershed, while tributaries north of Brooklin were generally dominated by cold
water habitats. In addition, groundwater input has moderated stream temperature during
thermal peaks in the tributary east of Brooklin. Tributaries downstream of Highway 401
were characterized as low gradient warm water habitats (Gartner Lee Limited, 1994).
Currently the Lynde Creek Watershed is characterized as a mixed system of cool and
warm-water streams (CLOCA, 2007). Despite urbanization and intensive agricultural
land use that increases stream temperature and decreases water quality, the Lynde
Creek Watershed generally supports both warm and coldwater fish communities that
are dominated by Brook Trout and Rainbow Trout populations (CLOCA, 2012; AECOM,
2010). However, Rainbow Trout has become a more common salmonid in Lynde Creek,
occupying headwaters of Lynde Creek that were historically inhabited by Brook Trout
(CLOCA, 2006; AECOM, 2010). Smallmouth Bass distributions have expanded over the
past years. Where this species was once only found south of Highway 401 it has been
reported north of Taunton Road, in the Heber Down Conservation Area in recent years
(CLOCA, 2006; AECOM, 2010). Common fish species identified within CLOCA’s
jurisdiction include Eastern Blacknose Dace, Common Shiner, White Sucker and Creek
Chub (CLOCA, 2006). Redside Dace has also been recorded by CLOCA as recently as
2006 in the Main and Heber Down subwatershed (CLOCA, 2006).
Fish collection records for the study area obtained from the MNRF indicated that in total,
59 sampling sites were recorded in the study area. In addition, 26 fish species have
been recorded in the Lynde Creek and its tributaries located within study area (a
complete list of species is provided in Appendix C.3). In general, the majority of the
species are representative of an intermediate to tolerant, mixed cool and warm water
fish community. Redside Dace (Clinostomus elongatus), a provincially and nationally
Endangered Species, was recorded in six of the sites situated within the study area
between 2000 and 2001 (refer to Exhibit 7 for locations). Redside Dace is a coolwater
species generally found in pools and slow flowing areas of small headwater streams
with a moderate to high gradient (Department of Fisheries and Oceans Canada, 2010).
Overhanging grasses and shrubs, as well as undercut banks, are an important part of
their habitat, as are in-stream boulders and large woody debris (COSEWIC, 2007).

2.5 Natural Heritage Features and Functions
The following sections provide a general description of the natural heritage features and
functions within the study area. The locations of these natural heritage features are
illustrated on Exhibit 8.
2.5.1 Designated Natural Areas
According to the MNRF’s NRVIS mapping (2011), there are Environmentally Sensitive
Areas (ESAs), the Locally Significant Dagmar Station Wetland and significant
woodlands within the study area (refer to Exhibit 8 for locations). No Areas of Natural
and Scientific Interest (ANSI), Provincially Significant Wetlands (PSWs), Provincial
Parks or Conservation Areas are located in the study area. Portions of the northern half
of the study area are situated on lands designated as part of the Greenbelt, including
protected countryside and natural heritage system, and the Oak Ridges Moraine,
respectively.
ANSIs present in the vicinity of the study area, however outside the study area limits
include the Provincially Significant Candidate Uxbridge Glen Major Forest Life ANSI, the
Regionally Significant Kinsale Raised Shoreline Earth Science ANSI and the
Provincially Significant Candidate Heber Down Iroquois Beach Life Science ANSI,
Provincially Significant Candidate Uxbridge-Glen Major Forest Life Science ANSI and
Provincially Significant Candidate Chalk Lake Life Science ANSI. In addition, three
PSWs are located in the vicinity of the study area, however outside the study area limits
and include the Glen Major Wetland Complex, the Chalk Lake Wetland Complex, and
the Heber Down Wetland Complex. A more detailed description of each of these
designated areas is provided below (please refer to Exhibit 8 for locations).
2.5.1.1 Significant Wetlands
As described in the MNRF’s Ontario Wetland Evaluation System Manual (3rd edition;
December, 2010), wetlands are lands that are seasonally or permanently flooded by
shallow water as well as lands where the water table is close to the surface, where the
presence of abundant water has caused the formation of hydric soils and has favoured
the dominance of either hydrophytic or water tolerant plants.
25
Exhibit 8: Natural Heritage Features
26
Evaluation and identification of wetlands as Provincially Significant is completed through
a standardized assessment process developed by the MNRF, the Ontario Wetland
Evaluation System (OWES). Wetlands are evaluated by assigning values to four key
components including the biological, social, hydrological and special features of the
wetland or wetland complex. Based on scoring, a wetland can fall into one of two
classes: Provincially Significant or Locally Significant (i.e., non-Provincially significant).
PSWs are protected under the Provincial Policy Statement 2014 (PPS).
Provincially Significant Wetlands
Glen Major Wetland Complex consists of a PSW that is located greater than 1 km
northwest of the study area. It is composed of 76 wetlands, which consist of swamps
(75%), marsh (18%), bog (1%) and other (6%). These wetlands are identified as
palustrine (82%) and isolated (18%) (AECOM, 2010). This PSW includes the Pleasure
Valley Bog (AECOM, 2010).
The Provincially Significant Chalk Lake Wetland Complex is situated greater than 1 km
north of the study area and consists of several wetland communities including marsh
(59%), swamp (25%) and rare fen (16%) habitats. This wetland is located in the
headwaters of the Lynde Creek and thus serves important ecological services of flood
attenuation and maintenance of water quality downstream (CLOCA, 2008).
The Provincially Significant Heber Down Wetland Complex (85 ha) is present
approximately 665 m south of the study area. According to the MNRF NHIC Natural
Areas Report (2010), this wetland complex consists of 16 wetlands comprising swamp
(96%) and marsh (4%) communities. The Heber Down Wetland Complex serves critical
hydrological functions that are important to the downstream ecological health of Lynde
Creek. It also provides important habitat for breeding area – sensitive bird species such
as Broad-winged hawk, Black and White Warbler, Scarlet Tanager and rare plant
species (CLOCA, 2008).
The Provincially Significant Whitby-Oshawa Iroquois Beach Wetland Complex is located
approximately 1 km south of the study area, along Conlin Road between Baldwin Street
and Simcoe Street. This Provincially Significant Wetland encompasses 198 ha,
consisting of many small wetlands that are less than 0.5 ha in size. This wetland
complex contains important amphibian breeding areas and uncommon wetland plant
communities and has hydrological significance (CLOCA, 2008).
27
All three of these PSWs occur more than 120 m away from the study area and
therefore, no potential impacts are anticipated to these natural features as result of the
proposed undertaking (refer to Exhibit 8 for locations). These natural features do not
represent constraints for the proposed undertaking.
Locally Significant Wetlands
The Locally Significant Dagmar Station Wetland (44.4 ha) is located within the study
area. The wetland is entirely comprised of swamp communities (100%) and consists of
soils that are predominately clay (80%) with areas of loams or silts and organic (20%)
(NHIC, 2010). The site type is 100% palustrine with a permanent or intermittent flow.
This wetland provides important winter cover for many wildlife species, with local
significance for Deer. In addition, Bullfrogs and Snapping Turtles have been previously
recorded in this wetland by field observers (NHIC, 2010). This Locally Significant
Wetland is encouraged to be conserved under Section 5.3.3.4 of the Whitby Official
Plan (Town of Whitby, 2016 Consolidation). According to the Ontario Regulation 42/16,
development is prohibited in wetlands, including areas within 120 m of PSWs and
wetlands greater than 2 hectares in size, and areas within 30 m of wetlands greater
than 0.5 hectares in size. Schedule B (Map B1d) of the Region’s Official Plan
designates the Dagmar Station Wetland and its wetland components as key natural
heritage and hydrological features and part of the Greenbelt Natural Heritage System
(Region of Durham, 2015 Consolidation).
Unevaluated Wetlands
The mapped locations of unevaluated wetlands under the jurisdiction of CLOCA were
requested and provided by CLOCA. Unevaluated wetlands identified within the study
area are shown on Exhibit 8. Some of these unevaluated wetlands are associated with
an environmentally sensitive area. According to the Ontario Regulation 42/16,
development is prohibited in wetlands, including areas within 120 m of PSWs and
wetlands greater than 2 hectares in size, and areas within 30 m of wetlands greater
than 0.5 hectares in size. Unevaluated wetlands are designated as key natural heritage
and hydrological features and part of the Greenbelt Natural Heritage System as shown
on Schedule B (Map B1d) of the Region’s Official Plan (Region of Durham, 2015
Consolidation).
28
2.5.1.2 Significant Woodlands
MNRF’s NRVIS mapping (2011) indicates that the study area contains a number of
isolated woodland. Section 5.3.7.1 of the Whitby Official Plan (2016 Consolidation)
designates mature woodlands as areas of high natural significance. The Whitby Official
Plan includes the designation and mapping for mature woodlands in the Official Plan
Schedule C. Within the Town of Whitby, a number of mature woodlands varying in size
with some larger, contiguous mature woodlands occur in the study area. Mature
woodlands are defined as “well stocked and established stands over 60 years old” with
particular emphasis on woodlands consisting of sugar maple, beech or hemlock.
Woodland areas are designated as key natural heritage and hydrological features and
part of the Greenbelt Natural Heritage System as shown on Schedule B (Map B1d) of
the Region’s Official Plan (Region of Durham, 2015 Consolidation). Exhibit 8 outlines
the locations of significant woodlands in the study area.
2.5.1.3 Areas of Natural Scientific Interest (ANSIs)
The MNRF evaluates ANSIs to determine whether they are provincially or regionally
(Locally) Significant. Provincially or regionally significant candidate ANSIs are
recommended by the MNRF for provincially or regionally significant ANSI status,
pending status approval. This evaluation takes into consideration the value of the area
for conservation, scientific study and education. ANSIs are designated as Earth
Science or Life Science depending on whether they contain significant geological
features (e.g., rock, fossil and landform features) or biological features (e.g., natural
landscapes, ecological communities, plant and animal species), respectively.
Provincially or Regionally Significant Candidate ANSIs are recommended by the MNRF
for Provincially or Regionally Significant ANSI status, pending status approval.
Life Science ANSIs
According to the MNRF’s NRVIS mapping (2011), the Provincially Significant Candidate
Heber Down Iroquois Beach Life Science ANSI is located more than 1 km south of the
study area. It is an area of land and water representing significant geological and
biological features.
The Provincially Significant Candidate Uxbridge-Glen Major Forest Life Science ANSI is
located more than 1 km west of the study area and contains a variety of vegetation
communities including maple-beech uplands, hemlock slopes, swamp cedar lowlands
and coniferous plantations (NHIC, 2010).
29
Chalk Lake is a Provincially Significant Candidate Life Science ANSI that is located
approximately 1 km north of the study area. Only boundary information is available at
this time for this feature through MNRF’s NRVIS mapping (2011).
All three ANSIs are located greater than 120 m from the limits of the study area and are
not considered a constraint to this study. In addition, no potential impacts to these
natural features are anticipated as result of the proposed undertaking (refer to Exhibit 8
for locations).
Earth Science ANSIs
The Regionally Significant Kinsale Raised Shoreline Earth Science ANSI is located
approximately 450 m south of the study area and is composed of drumlinized till plain
south of the Oak Ridges Moraine (NHIC, 2010). Much of this designated land had been
cleared for agricultural purposes (NHIC, 2010).
This ANSI is located greater than 120 m from the study area and therefore no potential
impacts to these natural features are anticipated as result of the proposed undertaking
(refer to Exhibit 8 for locations).
2.5.1.4 Provincial Parks
According to MNRF’s NRVIS Mapping (2011) and the Ontario Provincial Parks website,
there are no Provincial Parks or Conservation Reserves within the study area.
2.5.1.5 Conservation Areas
The Heber Down Conservation Area is located approximately 577 m south of the study
area. It contains 650 acres of valley lands, dry uplands and wet woodlands (NHIC,
2010). This Conservation Area also contains groundwater seeps and springs that
provide important groundwater recharge functions and specialized habitat for plant
species (NHIC, 2010; AECOM, 2010). This Conservation Area is located greater than
120 m from the study area and is not anticipated to be impacted by this study.
2.5.1.6 Environmentally Sensitive Areas (ESAs)
CLOCA undertook an Environmental Sensitivity Mapping Study prepared by Gartner
Lee Limited, to identify environmentally sensitive areas (ESAs) in the CLOCA
jurisdiction in 1978 (CLOCA, 2008). Identified ESAs were classified into sensitivity
categories between high and low. ESAs with high and medium-high sensitivities are
30
highly sensitive to disturbance and are considered to contain greater ecological
significance. Several high sensitivity and medium sensitivity ESAs are present within the
study area, as illustrated in Exhibit 5. The medium sensitivity ESA correlates to the
boundary of the Oak Ridges Moraine which contains a major recharge area that may be
impacted by major alternations or changes in land use (CLOCA, 2008). Portions of the
Oak Ridges Moraine also contain significant wildlife habitat, significant forests and
significant terrain features that are identified as areas of high sensitivity (CLOCA, 2008).
The Region of Durham recognizes the highest levels of sensitivity (high and medium-
high) as worthy of protection. ESAs are also designated as key natural heritage and
hydrological features and part of the Greenbelt Natural Heritage System as shown on
Schedule B (Map B1d) of the Region’s Official Plan (Region of Durham, 2015
Consolidation). Under Section 5.3.2.3 of the Town of Whitby Official Plan (2016
Consolidation), the Municipality requires an Environmental Impact Study (EIS)
developed in consultation with other authorities as appropriate for any development
proposed in or adjacent (120 m) to an ESA.
2.5.2 CLOCA Natural Heritage System
CLOCA has developed the Natural Heritage System (NHS) as a tool to manage
watershed resources in accordance with the Conservation Authorities Act, the Oak
Ridges Moraine Conservation Plan (ORMCP) and the Greenbelt Plan (CLOCA, 2012).
The NHS can be used by Municipalities, Conservation Authorities and planning
authorities as support in the implementation of the Natural Heritage Section of the
Provincial Policy Statement (PPS) (CLOCA, 2012). CLOCA’s NHS is comprised of two
mapped components: the functional NHS and the Targeted Terrestrial NHS. The
functional NHS includes an existing connected system comprised of natural features
such as core habitat areas, corridors, riparian corridors, species-at-risk corridors,
wetlands (≥ 0.5 ha), woodlands (≥ 0.5 ha), PSWs and ANSIs (CLOCA, 2012). The
Targeted Terrestrial NHS identifies areas where to increase natural cover so as to
establish and meet natural heritage targets (forest cover, wetland and riparian targets)
set out in the Environment Canada’s “How Much Habitat is Enough, A Framework for
Guiding Habitat Rehabilitation in Great Lakes Area of Concern” (CLOCA, 2012). The
Targeted Terrestrial NHS is mainly used as a tool in watershed plans and for land
acquisition programs. The CLOCA Natural Heritage System for the study area is shown
on Exhibit 9.

2.5.3 Rare Species
According to the MNRF NHIC Rare Species database, a total of six rare species have
been recorded in the vicinity of the study area, including three bird species, one insect
species, one plant species and one fish species, as presented in Table 5 below. Rare
species include species with designations by the Committee on the Status of
Endangered Wildlife in Canada (COSEWIC), species listed as Species at Risk in
Ontario (SARO), as well as Provincially Ranked S1 (Critically Imperiled) to S3
(Vulnerable) species. Species listed as Threatened or Endangered under the
Endangered Species Act, 2007 (ESA) receive individual and habitat protection.

Notes:
1 S-Rank: The natural heritage provincial ranking system (provincial S-rank) is used by the MNRF Natural Heritage
Information Centre (NHIC) to set protection priorities for rare species and natural communities. The following status definitions were taken from NatureServe Explorer’s (2015) National and Subnational Conservation Status Definitions available at http://explorer.natureserve.org/nsranks.htm:
SX - Presumed Extirpated—Species or community is believed to be extirpated from the province. Not located despite intensive searches of historical sites and other appropriate habitat, and virtually no likelihood that it will be rediscovered.
SH- Possibly Extirpated (Historical)—Species or community occurred historically in the province, and there is some possibility that it may be rediscovered. Its presence may not have been verified in the past 20-40 years. A species or community could become SH without such a 20-40 year delay if the only known occurrences in a province were destroyed or if it had been extensively and unsuccessfully looked for.
S1 - Critically Imperiled — Critically imperiled in the province because of extreme rarity (often 5 or fewer occurrences) or because of some factor(s) such as very steep declines making it especially vulnerable to extirpation from the province.
S2-Imperiled—Imperiled in the province because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation from the province.
S3 - Vulnerable—Vulnerable in the province due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation.
S4 - Apparently Secure—Uncommon but not rare; some cause for long-term concern due to declines or other factors.
S5 - Secure—Common, widespread, and abundant in the nation or state/province.
SNR - Unranked—Province conservation status not yet assessed.
33
SU - Unrankable—Currently unrankable due to lack of information or due to substantially conflicting information about status or trends.
SNA - Not Applicable — A conservation status rank is not applicable because the species is not a suitable target for conservation activities.
S#S# - Range Rank —A numeric range rank (e.g., S2S3) is used to indicate any range of uncertainty about the status of the species or community. Ranges cannot skip more than one rank (e.g., SU is used rather than S1S4).
Breeding Status Qualifiers
B - Breeding—Conservation status refers to the breeding population of the species in the province.
N - Nonbreeding—Conservation status refers to the non-breeding population of the species in the province.
M - Migrant—Migrant species occurring regularly on migration at particular staging areas or concentration spots where the species might warrant conservation attention. Conservation status refers to the aggregating transient population of the species in the province.
Note: A breeding status is only used for species that have distinct breeding and/or non-breeding populations in the province. A breeding-status S-rank can be coupled with its complementary non-breeding-status S-rank if the species also winters in the province, and/or a migrant-status S-rank if the species occurs regularly on migration at particular staging areas or concentration spots where the species might warrant conservation attention. The two (or rarely, three) status ranks are separated by a comma (e.g., "S2B,S3N" or "SHN,S4B,S1M").
Other Qualifiers
? -Inexact or Uncertain—Denotes inexact or uncertain numeric rank. (The ? qualifies the character immediately preceding it in the S-rank.)
2ESA Status: The Endangered Species Act 2007 (ESA) protects species listed as Threatened and Endangered on the Species at
Risk in Ontario (SARO) List on provincial and private land. The Minister lists species on the SARO list based on recommendations from the Committee on the Status of Species at Risk in Ontario (COSSARO), which evaluates the conservation status of species occurring in Ontario. The following are the categories of at risk:
END (Endangered) – A species facing imminent extinction or extirpation in Ontario.
THR (Threatened) – Any native species that, on the basis of the best available scientific evidence, is at risk of becoming endangered throughout all or a large portion of its Ontario range if the limiting factors are not reversed.
SC (Special Concern) – A species that may become threatened or endangered due to a combination of biological characteristics and identified threats.
NAR (Not at Risk) – A species that has been evaluated and found to be not at risk. 2 COSEWIC Status: COSEWIC (Committee on the Status of Endangered Wildlife in Canada) assigns a federal status
ranking for all species that it assesses. Rankings include:
END (Endangered) - A species facing imminent extirpation or extinction throughout its range.
THR (Threatened) - A species likely to become endangered if nothing is done to reverse the factors leading to its extirpation or extinction
SC (Special Concern) - A species of special concern because of characteristics that make it particularly sensitive to human activities or natural events, but does not include an extirpated, endangered or threatened species.
NAR (Not at Risk) - A species that has been evaluated and found to be not at risk.
DD (Data Deficient) - A wildlife species for which there is inadequate information to make a direct, or indirect, assessment of its risk of extinction.
3 ESA Status: The Endangered Species Act 2007 (ESA) protects species listed as Threatened and Endangered on the Species at
Risk in Ontario (SARO) List on provincial and private land. The Minister lists species on the SARO list based on recommendations from the Committee on the Status of Species at Risk in Ontario (COSSARO), which evaluates the conservation status of species occurring in Ontario. The following are the categories of at risk:
END (Endangered) – A species facing imminent extinction or extirpation in Ontario.
THR (Threatened) – Any native species that, on the basis of the best available scientific evidence, is at risk of becoming endangered throughout all or a large portion of its Ontario range if the limiting factors are not reversed.
SC (Special Concern) – A species that may become threatened or endangered due to a combination of biological characteristics and identified threats.
NAR (Not at Risk) – A species that has been evaluated and found to be not at risk.
It should be noted that two of these species were recorded within approximately the last
20 years within, or in the general vicinity, of the study area. These include the Redside
Dace (Clinostomus elongates) recorded in 2000, which is designated as Endangered
both provincially and nationally, and the provincially rare Pronghorn Clubtail (Gomphus
graslinellus) recorded in 1996. Redside Dace is a coolwater species generally found in
34
pools and slow flowing areas of small headwater streams with a moderate to high
gradient (Department of Fisheries and Oceans Canada, 2010; COSEWIC 2007).
Overhanging grasses and shrubs, as well as undercut banks, are an important part of
their habitat, as are in-stream boulders and large woody debris (COSEWIC 2007). The
Pronghorn Clubtail is a relatively small (47 to 53 mm long) and brightly coloured
dragonfly that is usually found perching on open ground at the water’s edge of ponds,
lakes and slow-moving streams (Paseka, 2010).
The NHIC also identified the remaining species as historical records, all of which are
designated as Endangered both provincially and nationally. Species observed greater
than 30 years ago are considered highly unlikely to still occur in or the general vicinity of
the study area. Nonetheless, the habitats of these species are discussed below as
follows:
Northern Bobwhite (Colinus virginianus) generally inhabits in early successional
habitats and requires a combination of grassland, cropland and brushy covers.
However, in Ontario it is more commonly found in cultivated agricultural fields
(COSEWIC, 2003a).
Loggerhead Shrike (Lanius ludovicianus) nests and forages in open habitats
including grasslands, sand-sage, pastures, agricultural areas and open woodlands.
In southern Ontario, the breeding population of this species is largely limited to
Lindsay, Kingston and Ottawa (COSEWIC, 2004).
Henslow’s Sparrow (Ammodramus henslowii) is an area-sensitive grassland species
and mainly nests in large patches of tallgrass prairies, wet meadows, and marsh
habitats. Although rare in southern Ontario, they can be found in abandoned fields,
lightly grazed pasture and wet meadows (COSEWIC, 2011).
Red Mulberry (Morus rubra) is a small, understorey tree that grows in moist,
deciduous forest including valleys, floodplains and sand pits in the Carolinian Forest
Zone in southern Ontario (Ambrose, 1987).
According to CLOCA 2013 Aquatic Species at Risk mapping (Conservation Ontario,
2013), Lynde Creek and its associated tributaries have been identified as having known
distributions of fish species designated as Extirpated, Endangered and/or Threatened
that are not currently on Schedule 1 of the federal Species at Risk Act (SARA), but are
anticipated to be added to Schedule 1. These species and their respective federal and
provincial conservation status rankings are identified in Table 6. Species listed in
35
Schedule 1 as Extirpated, Endangered or Threatened receive protection under SARA
while species currently under consideration for listing on Schedule 1 do not. However,
development within Lynde Creek and its associated tributaries should treat these
species as if they may be added to Schedule 1 by the time that the proposed
undertaking is initiated (DFO, 2013).

A request was made to the MNRF for information regarding the presence of Species at
Risk occurring in or adjacent to the study area. The response received from the MNRF
(on January 15, 2013) indicated that there are records of six Species at Risk within the
Northwest Brooklin EA Study Area, including Butternut (Juglans cinerea), Redside Dace
(Clinostomus elongatus), Barn Swallow (Hirundo rustica), Eastern Meadowlark
(Sturnella magna), Chimney Swift (Chaetura pelagica) and Bobolink (Dolichonyx
oryzivorus).
Butternut is designated as a nationally and provincially Endangered species. This tree
species commonly grows in deciduous forests with rich, moist, and well-drained soils
found along streams (COSEWIC, 2003b). Meanwhile, Bobolink is listed as a federally
and provincially Threatened species. Although historically this grassland bird species
preferred to breed in tall grass prairies, meadows and natural grassland, it is now more
commonly found in hayfields in southern Ontario (COSEWIC, 2010). Other Species at
Risk, including Barn Swallow (Hirundo rustica), Eastern Meadowlark (Sturnella magna)
and Chimney Swift (Chaetura pelagica) were also indicated to potentially occur in the
general vicinity of the study area. These additional species are all designated as
Threatened provincially and nationally and receive protection under the ESA. Therefore,
a permit may be required if the proposed undertaking could cause harm to any of these
abovementioned species or their habitat.
Based on rare species records collected by CLOCA in support of the 407 East EA
Natural Environment Field Investigation Report (Gartner Lee Limited, 2008) conducted
between May to July in 2003, 2006 and 2007, four provincially rare species, including
36
three Threatened species and one Special Concern species, were recorded in or within
the study area. These species include Bobolink, Barn Swallow, Eastern Meadowlark
and Canada Warbler.
Table 7 below provides an overall summary of all of the rare species records identified
through the background review and agency correspondence at the time of completion in
2014 for the Northwest Brooklin EA Study Area. A total of 12 Species at Risk records
were identified, including seven species listed as Endangered and five species listed as
Threatened under the ESA; these species receive individual and habitat protection
under the ESA. The remaining five species are listed as Special Concern under the
ESA and/or have provincial S-ranks of S1-S3; these do not receive protection under the
ESA.

2.6 Assessment of Natural Environment Constraints
Table 8 below summarizes the natural heritage features identified within the study area
through the review of secondary sources and their associated constraints to the
proposed undertaking. Natural heritage features including the Greenbelt Natural
Heritage System, the Oak Ridges Moraine, Regional Greenlands System, Locally
Significant Wetland and unevaluated wetlands, Significant Woodlands, Environmentally
Significant Areas, CLOCA regulated Areas, fish habitat, Species at Risk and species of
conservation concern were identified in the study area. The following natural heritage
features form medium to high levels of constraint to development as discussed below
(refer to Table 8):
High Development Constraint – Several mature woodlands identified by the Town of
Whitby Official Plan are present within the study area. The Town of Whitby considers
mature forest stands as areas of high ecological importance. These wooded areas
also provide important habitat for a wide diversity of plants and animals and are
identified as key natural heritage or hydrological features by the Durham Region
Official Plan. Development in mature woodlands requires the preparation of a Tree
Preservation Plan under Section 5.3.7.1 of the Town of Whitby Official Plan. In
addition, development within 120 m of a key natural heritage or hydrological feature
requires an EIS to determine the appropriate vegetation protection zone under
Section 2.2.12 of the Durham Region Official Plan.
High Development Constraint – Environmentally sensitive areas (ESAs) with high
and medium sensitivities to development have been identified in the study area. The
Region of Durham recognizes the highest levels of sensitivity (high and medium-
high) as worthy of protection. ESAs are also designated as key natural heritage and
hydrological features and part of the Greenbelt Natural Heritage System of the
Region’s Official Plan (Region of Durham, 2015 Consolidation). Under Section
5.3.2.3 of the Town of Whitby Official Plan (2016 Consolidation), the Municipality
requires an Environmental Impact Study (EIS) developed in consultation with other
authorities as appropriate for any development proposed in or adjacent (120 m) to
an ESA.
High Development Constraint – The 100-year floodline of Lynde Creek and its
tributaries is a Regulated Area identified by CLOCA. Lynde Creek also contains
important fish habitat that supports both warm and coldwater fish communities,
which may also contain potential aquatic Species at Risk. Development within a
Regulated Area requires permit from CLOCA. Furthermore, any development within
38
fish habitat requires authorization from the Minister of Fisheries and Oceans Canada
under the Fisheries Act.
High Development Constraint – Species at Risk listed as Endangered and
Threatened and their habitats have the potential to occur within the study area.
These species and their habitats receive protection under the ESA. A permit from
the MNRF may be required if development could destroy or cause harm to the
identified Species at Risk and its habitat. As such, field investigations focused on
identifying Species at Risk during subsequent project phases is recommended.
Medium Development Constraint – Species of conservation concern (S1 to S3) and
their habitats have the potential to be present within the study area. Although these
species are not protected under the ESA, the habitats of these species are
considered as Significant Wildlife Habitat which are identified as a key natural
heritage feature by the Region’s Official Plan and by the Provincial Policy Statement
(PPS) (2014). As such, field investigations focused on identifying species of
conservation concern during subsequent project phases is recommended. An EIS is
required if development is proposed in or on adjacent lands of a Significant Wildlife
Habitat.
Medium Development Constraint – Dagmar Wetland Station, a Locally Significant
Wetland, and several unevaluated wetlands occur within the study area. Dagmar
Wetland Station provides important winter cover for many wildlife species including
potentially rare species. For this reason, the Town of Whitby encourages the
conservation of this wetland (Town of Whitby, 1994). Unevaluated wetlands are also
identified as key natural heritage and hydrological features and part of the Greenbelt
Natural Heritage System (Region of Durham, 2008). Although these wetlands are
not protected under the PPS, development is prohibited in areas within 120 m of
wetlands greater than 2 hectares in size and areas within 30 m of wetlands greater
than 0.5 hectares in size unless an application for permission from CLOCA is
prepared and approved.

3. Brooklin TMP Study Area – Addendum to Descriptions of Existing Natural Environment
The following sections provide additional natural environment information for the
Brooklin TMP Study Area that were not previously documented in Section 2 as part of
the Northwest Brooklin EA Study Area. In addition, in response to the comments
received from the Miller Planning Group pertaining to the preferred road alignment of
the mid-block arterial roadway, a desktop review to assess the feasibility of the
proposed suggestions to the alignment was completed. The details of the desktop
review and additional natural heritage information related to this study area are
provided in the following sections. This information was provided to the Town in support
of the response to Miller Planning, which is included in Appendix H.
3.1 Methods
The following secondary sources were used to update the natural environment
conditions based on the Brooklin TMP Study Area:
MNRF NRVIS mapping;
MNRF NHIC Rare Species and Natural Area Records;
Ontario Breeding Bird Atlas (2001-2005);
Central Lake Ontario Conservation Authority reports, including Ecological Land
Classification mapping and flora and fauna records;
Watershed and subwatershed studies;
407 East Individual Environmental Assessment (IEA) and Preliminary Design Study
(AECOM, 2010);
Transportation Master Plan Study;
Quaternary and surficial geological mapping from the Ontario Geological Survey
(OGS);
44
Bedrock geological mapping from OGS;
Ministry of Environment and Climate Change (MOECC) Water Well Records;
MOECC Permit to Take Water (PTTW) Records;
Soils mapping from the Ontario Ministry of Agriculture, Food and Rural affairs
(OMAFRA), as well as Agriculture and Agri-Food Canada; and
Source water protection and groundwater vulnerability mapping available from the
Central Lake Ontario Source Protection Plan.
It should be noted that correspondence with agencies (e.g., MNRF, Conservation
Authority, DFO) was not initiated for the portion of Brooklin TMP Study Area located
between Winchester Road and Taunton Road since there are no alternative solutions
proposed in this area. For the purposes of the mid-block arterial roadway, a
comprehensive background information review, including contacting agencies for
additional natural heritage data (e.g., ELC, flora and fauna records, rare species
records, etc.), should be completed for any future EA works.
3.2 Physical Environment
3.2.1 Physiography
The study area is situated within two (2), as mapped by Chapman and Putnam (1984);
the South Slope physiographic region; and the Iroquois Plain physiographic region. The
South Slope physiographic region dominates the majority of the study area north of
Winchester Road, whereas the Iroquois Plain physiographic region encroaches onto the
south portion of the study area limits.
The South Slope physiographic region is an area defined as the southern slope of the
Oak Ridges Moraine. Within the study area, the South Slope is comprised of a till plain
that contains drumlins in the southern portion. Streams typically flow down the slope
with minimal meandering in a generally southward direction, carving sharp valleys in the
surficial till sediments.
The Iroquois Plain is described as lowland bordering on Lake Ontario, representing the
historic shoreline of Lake Iroquois during the last glacial period. Permeable sands and
depositional features such as cliffs, bars, beaches and boulder pavements comprise
45
much of the northern portion of the region. Within the study area the Iroquois Plain is
dominated by sand plains and also transects a prominent beach landform.
3.2.2 Geological Conditions
3.2.2.1 Overburden Geology
The study area is underlain by thick successions of unconsolidated sediments, known
as overburden, deposited during the Quaternary Period. Overburden deposits within
the study area were laid down primarily by glacial lakes and the Laurentide Ice Sheet
during the Wisconsinan glaciation of the Pleistocene approximately 20,000 years ago.
The study area was subject to a complex glacial history resulting in extremely complex
stratigraphy in the overburden deposits.
Overburden thickness across the study area was assessed through a review of MOECC
water well record information. Based on this review, overburden thickness ranges
between approximately 0 m and 143 m, with an average thickness of about 37 m.
Surficial geology within the study area is reported by the Ontario Geological Survey
(2010) and shown on Exhibit 10 to consist of i) Modern alluvial deposits (clay, silt,
sand, gravel, and organic remains) within the Lynde Creek river valley and associated
tributaries, ii) clay to silt-textured till deposits that dominate the north portions of the
study area, iii) sandy silt to silty sand-textured tills within the central and southern
portion of the study area, iv) coarse-textured (sand and gravel) glaciolacustrine deposits
within the south portion of the study area and also occurring as isolated outcrops within
the northern portion of the study area, v) an isolated outcrop of ice-contact stratified
deposits of sand and gravel occurring in the northwestern portion of the study area
along Coronation Road south of Myrtle Road West, vi) fine-textured glaciolacustrine
deposits of silt and clay occurring in the northeastern portion of the study area, and vii)
organic deposits within the northwestern portion of the study area, associated with the
coarse-textured glaciolacustrine deposits.

Exhibit 10: Surficial Geology
47
3.2.2.2 Bedrock Geology
Regional bedrock geology was interpreted through the review of published bedrock
geology mapping (Hewitt, 1966 and OGS, 2011), bedrock topography mapping (Holden
et al., 1993), as well as the MOECC water well record information for locations within
the study area (MOECC, 2017).
According to the OGS (2011), the Blue Mountain Formation of Upper Ordovician age
underlies the study area. The Blue Mountain Formation is described as a dark blue-
grey to brown to black shale with thin interbeds of limestone or calcareous siltstone
(Armstrong and Dodge, 2007).
3.2.2.3 Soils and Agricultural Capability
Based on Canada Land Inventory Agricultural Capability Mapping prepared by the
MNRF, the majority of undeveloped portions of the study area consist of Class “1” and
Class “2” soils. These soil classes have the highest capability to support agricultural
land use activities.
3.2.3 Hydrogeological Conditions
3.2.3.1 Groundwater Use
Exhibit 11 depicts the approximate locations of the MOECC water well records for all
water supply wells within the study area and highlights the primary use of these wells. It
should be noted that location inaccuracies of recorded water well supplies do exist
within the MOECC Water Well Information System, from which the water well record
information was obtained. In considering the information provided herein, it should be
recognized that dug wells and sand point wells commonly are not registered in the
MOECC database and may account for a number of additional wells within and local to
the study area that are not reflected in the following discussion.
Review of the MOECC database has identified a total of approximately 1,727 well
records within the study area. A review of the water well records indicates that the wells
extend to depths ranging from approximately 3 m to 223 mBGS, and are primarily
completed within overburden sediments (57%).
48
Exhibit 11: MOECC Water Well Records
49
As shown in Table 9, available well records indicate that 55% of groundwater use in
study area is for domestic use, followed by monitoring or dewatering purposes (19%),
farm and agricultural use (4%), industrial / commercial use (3%), and municipal and/or
public supply (1%). Approximately 12% of MOECC water well records did not specify
the well use and therefore are classified as ‘Unknown’. Less than 4% of the MOECC
water well records indicate the well is not used, accounting for dry wells.

Other 2 3 m to 29 m 2 Unknown
Unknown 199 3 m to 166 m 41 Overburden, 8 Bedrock, 150 Unknown
3.2.3.2 Depth to Water Table
Depth to the water table was characterized by reviewing static water levels recorded in
available MOECC water well records. A total of 1,081 records were identified that
report a static water level. The static water levels within these well records range
between about 10 m above ground surface (artesian) and 47 m below ground surface.
Static water levels may fluctuate considerably in response to changes in precipitation
patterns, seasonal fluctuations, and local pumping within the aquifer.
The presence of organic deposits associated with coarse-textured surficial deposits may
indicate the occurrence of groundwater upwelling and/or seeps and springs within these
areas where the water table may be close to ground surface. In addition, where coarse-
textured deposits are confined by an overlying more impermeable deposit (i.e., clay to
silt-textured till) artesian groundwater conditions may exist.
50
3.2.3.3 Source Water Protection
The study area is within the Central Lake Ontario Source Protection Area. Within this
area, policies related to a list of prescribed activities, have been developed for the
purposes of protecting the municipal drinking water sources in this jurisdiction. As part
of the source water protection work, the vulnerability of these sources to a threat
presented by an activity that occurs on land has been assessed. The four types of
vulnerable areas that may have associated Source Water Protection Policies include:
Highly Vulnerable Aquifers (HVAs);
Significant Groundwater Recharge Areas (SGRAs);
Intake Protection Zones (IPZs); and
Wellhead Protection Areas (WHPAs)
According to the Credit Valley, Toronto and Region, and Central Lake Ontario (CTC)
Source Protection Plan (2015), there are no surface water or associated IPZ for
municipal purposes within the study area. In addition, there are no groundwater takings
for municipal purposes or associated WHPAs within the study area.
According to the Central Lake Ontario Assessment Report, HVA and SGRA do exist
within the study area and are associated with portions of the coarse-textured
glaciolacustrine deposits found within the study area. Activities within these vulnerability
areas are not considered to be a significant threat to municipal drinking water sources
and therefore do not have associated land use or activity policies.
Geomorphology
The Miller Planning reports primarily focus on natural environment and geomorphic
impacts. These criteria, as well as other criteria, will be considered as part of a future
EA. The geomorphology assessment ranks the creek crossings only, not the remainder
of the routes that were identified with each of the creek crossings, so potentially route
options could be improved with combinations of options.
The TRCA (2004) protocol requires that relic features be accommodated within the
defined meander belt width, which would result in the larger dimension identified by
Beacon Environmental (2016). GeoMorphix (2016) refer to the relic feature, formed
through an avulsion, in their historic assessment “This is a unique avulsion, as it
proves the channel is capable of making significant movements across the
51
floodplain”. However, they did not include it in their meander belt width delineation
(see Figures 1-3 in Beacon 2016 report).
In comparing the Beacon Environmental (2016) and GeoMorphix (2016) reports, no
100yr erosion rates appear to have been calculated by either of the consultant agencies
to reflect channel movement since the avulsion. It is also notable that, since the channel
has previously adjusted through avulsion, 100 yr erosion rates do not appropriately
characterise potential erosion risk. It is understood that a factor of safety (10% for L1
and L2, and 20% for L1-1 and L2-1) was added to the Geomorphix (2016) calculations,
whereas based on the information we have from the Beacon report, it is unclear
whether this was added to the meander belt width.
The erosion risk within the delineated meander belt width is related to the potential for
channel adjustment to occur within this zone in the future, as has been documented in
the past. The reach (L2) is characterized as being “In Adjustment”; therefore it would
appear prudent to account for this risk in the crossing design.
Beacon (2016) identifies the meander belt width to be wider than Geomorphix (2016) in
order to include the channel position prior to avulsion. As described above, this reflects
the TRCA (2004) protocol by taking into account historic channel positions. The
crossing length show in Figure 3 of the Beacon (2016) report is consequently larger. It
is noted that this crossing alignment is at a significant angle to the watercourse and
consequently longer than if it was perpendicular, as would typically be recommended.
The proposed crossing identified in Figure 1 (Beacon 2016 report) is on the downstream
end of a meander bend. Proposed crossings are not recommended at active meander
bends and better suited to straighter channel sections. However, the creek is highly
meandering therefore a straighter section is not available. It is also notable that this
crossing location is narrower, more perpendicular and outside of the zone of previous
channel avulsion, in comparison with Figures 2 and 3 (Beacon 2016 report). Crossings
should be located at locally stable sections of the channel away from active erosion,
which is difficult to identify from the information available.
As long as a crossing is built outside of the meander belt width, from a
geomorphological perspective there should be sufficient space for the watercourse to
adjust over time without adversely impacting the structure or the creek.
The second proposed crossing (Figure 2 of the Beacon report) is located at the
confluence of a tributary channel and the main channel. Confluences can be highly
52
dynamic and channel adjustment can be unpredictable – this area also exhibited
evidence of significant historic channel planform change. The crossing identified in
Figure 3 (Beacon 2016 report) is also longer and in the zone subject to previous
channel avulsion. The narrower, more perpendicular crossing illustrated in Figure 1
appears preferable in comparison to Figures 2 and 3.
The Candevcon report identified some potential issues with the 2010 TMP preferred
route Option K, including conflicts with Hydro towers, and potential conflict with the
existing St. Thomas Street/Anderson Street intersection. The proposed Mid-Block
Arterial corridor alignment has been refined from that shown in the November 2015
Options Report, and will continue to be refined, to mitigate conflicts with the natural
environment, the hydro corridor and recognizing MTO intersection spacing criteria.
3.3 Aquatic Environment
The Northwest Brooklin EA Study Area was contained entirely within the Lynde Creek
Watershed. The Brooklin TMP Study Area now overlaps small sections of Oshawa
Creek Watershed in the east, Pringle Creek Watershed in the southeast, and Goodman
Creek Watershed in the south. Correspondence with agencies (MNRF and DFO) were
not initiated for the Brooklin TMP Study Area. As such, the information provided in
Section 2.4 remains the same. However, it is recommended that these agencies be
contacted to confirm whether more recent fish records are available.
3.4 Terrestrial Environment
Correspondence with agencies (e.g., MNRF, CLOCA, DFO) was not initiated for the
portion of Brooklin TMP Study Area located between Winchester Road and Taunton
Road since there are no alternative solutions proposed in this area. For the purposes of
the mid-block arterial roadway, a comprehensive background information review,
including contacting agencies for additional natural heritage data (e.g., ELC, flora and
fauna records, rare species records, etc.) should be completed for any future EA works.
As such there is no additional information to be added to terrestrial environment other
than what is presented in Section 2.3.1 of this Report.
53
3.5 Natural Heritage Features
3.5.1 Designated Natural Areas
According to the MNRF’s NRVIS mapping (2011), the Brooklin TMP Study Area
contains Areas of Natural and Scientific Interest (ANSI), PSWs, and a Conservation
Area that were not present in the Northwest Brooklin EA Study Area. These designated
natural areas are mapped on Exhibit 12.
3.5.2 Significant Wetlands
Provincially Significant Wetlands
The Provincially Significant Heber Down Wetland Complex and Provincially Significant
Whitby-Oshawa Iroquois beach Wetland Complex now occur within the extended limits
of the Brooklin TMP Study Area where they didn’t before in the Northwest Brooklin EA
Study Area (refer to Section 2.5.1.1 for descriptions of these PSWs). The locations of
these PSWs are shown on Exhibit 12 below. There are also additional unevaluated
wetlands located south of Winchester Road as shown on Exhibit 12.
The Provincially Significant Whitby-Oshawa Iroquois Beach Wetland Complex is located
in the vicinity of the mid-block arterial roadway and is further addressed in response to
Miller Planning Group’s comments in Appendix H. Three units of this PSW occur
immediately along Conlin Road in the vicinity of the intersection with Thickson Road.
There is a large wetland unit on the southeast quadrant of the Conlin Road / Thickson
Road intersection and a smaller unit occurs about 400 m east of Thickson Road on the
north side of Conlin Road. Another small unit occurs on the south side of Conlin Road
about 100 m west of Thickson Road.
Since PSWs are protected under the Provincial Policy Statement, all development
should avoid encroaching on a PSW. It appears that intrusion into this PSW could be
largely avoided if Conlin Road were only widened on the north side. However, the
east-most unit is immediately along the north side of Conlin and therefore, the widening
would have to occur on the south side to avoid this PSW in this area (refer to Appendix
H).
54
Exhibit 12: Natural Heritage Features for the Brooklin TMP Study Area
55
An Environmental Impact Study is required for any proposed development within 120 m
of a PSW, even if there is no proposed intrusion. Consequently the characteristics and
sensitivities of the wetland would need to be studied and the precise boundaries
confirmed. Mitigation measures would need to be recommended to prevent negative
impacts to the PSW. The MNRF is not always involved in developments adjacent to
PSWs, it is often left to Municipalities; however, if any intrusion is proposed, MNRF will
almost certainly review and be involved in the application. MNRF strongly discourages
any intrusion into PSWs, but where it is absolutely necessary an elaborate
compensation plan is typically required. In addition, according to the Ontario Regulation
42/16, development is prohibited in areas within 120 m of PSWs unless a permit is
issued by CLOCA.
3.5.3 Significant Woodlands
There are additional wooded areas located south of Winchester Road within the
Brooklin TMP Study Area, including mature woodlands as shown on Schedule C of the
Town of Whitby Official Plan.
3.5.4 Areas of Natural and Scientific Interest (ANSIs)
Life Science ANSIs
According to the MNRF’s NRVIS mapping (2011), the Provincially Significant Candidate
Heber Down Iroquois Beach Life Science ANSI is now located in the Brooklin TMP
Study Area. It is an area of land and water representing significant geological and
biological features.
Earth Science ANSIs
The Regionally Significant Kinsale Raised Shoreline Earth Science ANSI is now located
adjacent to the Brooklin TMP Study Area’s western boundary and is composed of
drumlinized till plain south of the Oak Ridges Moraine (NHIC, 2010). Much of this
designated land had been cleared for agricultural purposes (NHIC, 2010).
3.5.5 Conservation Areas
The Heber Down Conservation Area is now located within the Brooklin TMP Study Area
(refer to Section 2.5.1.5 for description).
56
3.5.6 Rare Species
According to the MNRF NHIC Rare Species database (last query completed on May 24,
2017), a total of nine rare species have been recorded in the vicinity of the Brooklin
TMP Study Area, including five bird species, one insect species, one plant species, one
reptile species, and one fish species, as presented in Table 10 below. Rare species
include species with designations by the Committee on the Status of Endangered
Wildlife in Canada (COSEWIC), species listed as Species at Risk in Ontario (SARO), as
well as Provincially Ranked S1 (Critically Imperiled) to S3 (Vulnerable) species. Only
one new Species at Risk was identified for the Brooklin TMP Study Area that was not
identified previously in 2014 for the Northwest Brooklin EA Study Area (refer to Table 7
in Section 2.5.3), which was the Blanding’s Turtle (Emydoidea blandingii).

See notes under Table 5.
It should be noted that four of these species were recorded in or near the study area
within the last 20 years. These include Redside Dace (Clinostomus elongatus), which is
designated as Endangered both provincially and federally, Blanding’s Turtle
(Emydoidea blandingii), which is designated as Endangered federally and Threatened
provincially, and Bobolink (Dolichonyx oryxivorus), Eastern Meadowlark (Sturnella
magna), which are provincially and federally Threatened.
It should be noted that correspondence with agencies (e.g., MNRF, Conservation
Authority, DFO) was not initiated for the portion of Brooklin TMP Study Area located
between Winchester Road and Taunton Road since there are no alternative solutions
proposed in this area. The relevant agencies (MNRF, CLOCA, DFO) should be
contacted for Species at Risk records for any future EA works, both for the purposes of
57
the mid-block arterial roadway as well as to update Species at Risk information for the
Northwest Brooklin EA Study Area and Brooklin TMP Study Area.
3.5.7 Assessment of Natural Environment Constraints
Given that there are no proposed alternative solutions located south of Winchester
Road within the TMP Brooklin Study Area, an assessment of natural environment
constraints for the additional natural heritage features identified in Brooklin TMP Study
Area that were not previously documented in Section 2 as part of the Northwest
Brooklin EA Study Area was not required, with the exception of the Iroquois Beach
Provincially Significant Wetland Complex which is located in close vicinity of the mid-
block arterial corridor. Natural heritage constraints associated within this PSW for the
alignment suggested by the Miller Planning Group are identified in Appendix H.
Essentially, PSWs are protected under several higher and lower-tied Municipal planning
acts and other regulations, including the Provincial Policy Statement, Durham Region
Official Plan, Town of Whitby Official Plan and CLOCA’s Ontario Regulation 42/06
(2006, 2013 Consolidation) which prohibit development within PSWs. However,
development within 120 m of PSWs may be permitted provided that an Environmental
Impact Study is completed.
Several regulatory changes have occurred since completion of the 2014 report prepared
in support of the Northwest Brooklin Bypass Environmental Assessment (EA). These
are summarized below.
3.5.7.1 Fisheries Act Amendment
On November 25, 2013, amendments to the Fisheries Act came into effect whereby the
amendment combined the previous section 32 (killing of fish by means other than
fishing) and section 35 (prohibiting the harmful alteration, disruption or destruction of
fish habitat) to the new prohibition that prohibits ‘serious harm to fish,’ which is defined
as “the death of fish, or any permanent alteration or destruction of fish habitat.” The
2013 amendment focuses the Act on protecting the productivity of recreational,
commercial and Aboriginal fisheries.
Along with the changes to the Fisheries Act, Fisheries and Oceans Canada’s (DFO)
Habitat program was also changed to the Fisheries Protection Program (FPP). Under
this new program, a streamlined approvals process was created where-by applicants
are now able to self-assess their projects to determine if the DFO is required to review
the project. Potential applicants intending to perform work or activities that may affect
58
fish or fish habitat are encouraged to engage a Qualified Environmental Professional to
determine whether the proposed works near water requires a review by DFO. If the
project cannot avoid serious harm to fish and/ or fish habitat and is not included in any
of the types of waterbodies and/ or projects where DFO review is not required, a
Request for Review form must be submitted to DFO. These actions help ensure that no
serious harm to fish or fish habitat occurs and also satisfy all regulatory commitments as
issued under the FPP.
3.5.7.2 Species at Risk Status Updates
Species at Risk in Canada and Ontario are regularly reassessed by COSEWIC and
COSSARO, respectively. Of the species identified in Section 2.5.3, none of the
provincial statuses have changed since completion of the 2014 report. However, the
protection status under the ESA of species not identified in Section 2.5.3 were up listed
since the completion of this report, such as bat Species at Risk. In addition, one of the
species identified have had status changes at the federal level. Redside Dace is now
listed as Endangered under Schedule 1 of the federal Species at Risk Act. Therefore,
relevant agencies (i.e., MNRF, CLOCA, DFO) should be contacted for Species at Risk
records to update Species at Risk information provided below for any future EA study to
inform any permitting requirements under the ESA.

Subject NW Brooklin By-Pass - Preliminary Groundwater Impact Assessment
From Erin Wilson
Date March 28, 2013 60278570
The purpose of this memorandum is to provide details on existing hydrogeological conditions presentwithin the study area for the Northwest Brooklin Transportation Class Environmental Assessment.This phase of investigation includes a preliminary desktop study to characterize existing geologicaland hydrogeological conditions, through a background review of current geological mapping, and todescribe potential groundwater impacts related to the project.
Results of the investigation are summarized in the attached table and the accompanied surficialgeology map. Approximately eleven (11) geological deposits are found at surface within the area ofinvestigation (see surficial geology map attached). Each surficial deposit has been described forimportant hydrogeological properties, such as estimated hydraulic conductivity, aquifer potential, andrecharge/discharge potential and potential impacts to groundwater quality and quantity (refer toattached table). The susceptibility to groundwater impacts from the proposed roadway for each of thesurficial deposit, as it relates to the different hydrogeological properties, is rated as Low-1, Moderate-2 or High-3. An overall impact rating was then calculated for comparison purposes. Surficial depositswith a high overall impact rating (e.g., 13-15) are considered to be more susceptible to groundwaterquality and/or quantity impacts than those rated with a low overall impact rating (e.g., 5-9). Theaccompanied groundwater impact map illustrates the results of the overall impact rating for eachsurficial deposit and highlights areas of potential high groundwater impact related to the constructionand operation of a new roadway.

is used rather than S1S4).
Breeding Status Qualifiers
the aggregating transient population of the species in the province.Note: A breeding status is only used for species that have distinct breeding and/or non-breeding populations in the province. A breeding-status S-rank can be coupled with its complementary non-breeding-status S-rank if the species also winters in the province, and/or a migrant-status S-rank if the species occurs regularly on migration at particular staging areas or concentration spots wherethe species might warrant conservation attention. The two (or rarely, three) status ranks are separated by a comma (e.g., "S2B,S3N" or "SHN,S4B,S1M").
3 ESA Status: The Endangered Species Act 2007 (ESA) protects species listed as Threatened and Endangered on the Species at Risk in Ontario (SARO) List on provincial and private land. TheMinister lists species on the SARO list based on recommendations from the Committee on the Status of Species at Risk in Ontario (COSSARO), which evaluates the conservation status of speciesoccurring in Ontario. The following are the categories of at risk:
factors are not reversed.
2 COSEWIC Status: COSEWIC (Committee on the Status of Endangered Wildlife in Canada) assigns a federal status ranking for all species that it assesses. Rankings include:
END (Endangered) - A species facing imminent extirpation or extinction throughout its range.THR (Threatened) - A species likely to become endangered if nothing is done to reverse the factors leading to its extirpation or extinctionSC (Special Concern) - A species of special concern because of characteristics that make it particularly sensitive to human activities or natural events, but does not include an extirpated, endangeredor threatened species.NAR (Not at Risk) - A species that has been evaluated and found to be not at risk.DD (Data Deficient) - A wildlife species for which there is inadequate information to make a direct, or indirect, assessment of its risk of extinction.

Table created using data from The Ontario Freshwater Fish Life History Database (http://www.fishdb.ca/home.htm) accessed May 20, 2013
GH: Possibly Extinct; missing; known from only historical occurrences but still some hope of rediscovery.
Northwest Brooklin - MNR Fish Records- Lynde Creek Watershed - Dot 172
COSEWIC Status: Species designation assigned by the Committee on the Status of Endangered Wildlife in Canada.Extinct (X): A wildlife species that no longer exists.Extirpated (XT): A wildlife species no longer existing in the wild in Canada, but occurring elsewhere.Endangered (E): A wildlife species facing imminent extirpation or extinction.Threatened (T): A wildlife species likely to become endangered if limiting factors are not reversed.Special Concern (SC): A wildlife species that may become a threatened or an endangered species because of a combination of biological characteristics and identified threatsNot at Risk (NAR): A wildlife species that has been evaluated and found to be not at risk of extinction given the current circumstances.Data Deficient (DD): A wildlife species for which there is inadequate information to make a direct, or indirect, assessment of its risk of extinction.
GRank (Global Rank): Global conservation status ranks are assigned by NatureServe scientists with input from relevant natural heritage member programs and experts on particular taxonomic groups. These ranks reflect an assessment of the condition of the species across its entire range.
GX: Presumed Extinct; not located despite intensive searches and virtually no likelihood of rediscovery.
NX: Presumed Extirpated; species is believed to be extirpated from the nation. Not located despite intensive searches of historical sites and other appropriate habitat, and virtually no likelihood that it will be rediscovered.
G1 : Critically Imperiled; at very high risk of extinction due to extreme rarity (often 5 or fewer populations), very steep declines, or other factors.
G2: Imperiled; at high risk of extinction due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors.
G3 : Vulnerable; at moderate risk of extinction due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors.
G4: Apparently Secure; uncommon but not rare; some cause for long-term concern due to declines or other factors.
G5 : Secure; common, widespread, and abundant.
G#G# : Range Rank; a numeric range rank is used to indicate the range of uncertainty in the status of a species.
GU: Unrankable; currently unrankable due to lack of information or due to substantially conflicting information about status or trends.
GNR : Unranked; global rank not yet assessed.
GNA: Not Applicable; a conservation status rank is not applicable because the species is not a suitable target for conservation activities (i.e., hybrid).
? : Inexact Numeric Rank; denotes inexact numeric rank (e.g., G2?).
NRank (National Rank): National conservation status ranks in Canada are assigned similar to global ranks. The condition of a species can vary from one country to another, and national conservation status ranks document its condition in a particular country.
SRank (Subnational Rank): Subnational conservation status ranks are assigned for Ontario by the Natural Heritage Information Centre (NHIC) to set protection priorities for rare species.
NH : Possibly Extirpated; species occurred historically in the nation, and there is some possibility that it may be rediscovered. Its presence may not have been verified in the past 20-40 years
N1: Critically Imperiled; critically imperiled in the nation because of extreme rarity (often 5 or fewer occurrences) or because of some factor(s) such as very steep declines making it especially vulnerable to extirpation.
N2: Imperiled; imperiled in the nation because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation.
N3: Vulnerable; vulnerable in the nation due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation.
N4: Apparently Secure; uncommon but not rare; some cause for long-term concern due to declines or other factors.
N5 : Secure; common, widespread and abundant in the nation.
NNR: Unranked; national conservation status not yet assessed.
NU: Unrankable; currently unrankable due to lack of information or due to substantially conflicting information about status or trends.
NNA : Not Applicable; a conservation status rank is not applicable because the species is not a suitable target for conservation activities (i.e., exotic or hybrid).
N#N# : Range Rank; a numeric rank is used to indicate the range of uncertainty about the status of the species.
?: Inexact or Uncertain; denotes inexact or uncertain numeric rank.
?: Inexact or Uncertain; denotes inexact or uncertain numeric rank.
SX: Presumed Extirpated; species is believed to be extirpated from the province. Not located despite intensive searches of historical sites and other appropriate habitat, and virtually no likelihood that it will be rediscovered.
SH: Possibly Extirpated; species occurred historically in the province, and there is some possibility that it may be rediscovered. Its presence may not have been verified in the past 20-40 years.
S1 : Critically Imperiled; critically imperiled in the province because of extreme rarity (often 5 or fewer occurrences) or because of some factor(s) such as very steep declines making it especially vulnerable to extirpation.
S2: Imperiled; imperiled in the province because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation.
S3: Vulnerable; vulnerable in the province due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation.
S4: Apparently Secure; uncommon but not rare; some cause for long-term concern due to declines or other factors.
S5 : Secure; common, widespread and abundant in the province.
SNR: Unranked; provincial conservation status not yet assessed.
SU : Unrankable; currently unrankable due to lack of information or due to substantially conflicting information about status or trends.
SNA: Not Applicable; a conservation status rank is not applicable because the species is not a suitable target for conservation activities (i.e., exotic or hybrid).
S#S#: Range Rank; a numeric rank is used to indicate the range of uncertainty about the status of the species.
