3131 Lower Don River West Lower Don River West 4.0 DESCRIPTION
Lower Don River West Environmental Study Report Remedial Flood Protection Project 4.0 DESCRIPTION OF LOWER DON 4.1 The Don River Watershed The Don River is one of more than sixty rivers and streams flowing south from the Oak Ridges Moraine. The River is approximately 38 km long and outlets into the Keating Channel, which then conveys the flows into Toronto Harbour and Lake Historic Watershed Ontario. The entire drainage basin of the Don urbanization of the river's headwaters in York River is 360 km2. Figure 4.1 and Figure 4.2, on the Region began in the early 1980s and continues following pages, describe the existing and future today. land use conditions within the Don River Watershed. Hydrologic changes in the watershed began when settlers converted the forests to agricultural fields; For 200 years, the Don Watershed has been many streams were denuded even of bank side subject to intense pressures from human vegetation. Urban development then intensified settlement. These have fragmented the river the problems of warmer water temperatures, valley's natural branching pattern; degraded and erosion, and water pollution. Over the years often destroyed its once rich aquatic and during the three waves of urban expansion, the terrestrial wildlife habitat; and polluted its waters Don River mouth, originally an extensive delta with raw sewage, industrial/agricultural marsh, was filled in and the lower portion of the chemicals, metals and other assorted river was straightened. contaminants. Small Don River tributaries were piped and Land clearing, settlement, and urbanization have buried, wetlands were "reclaimed," and springs proceeded in three waves in the Don River were lost. -

Environmental Assessment chapter 3. description of the potentially affected environment 3. Description of the Potentially Affected Environment This chapter is divided into four different sections which describe different components of the baseline or existing environmental conditions. The first section describes the river characteristics which will influence the development of alternatives. This information has been separated from the remaining description of the natural environment such that some emphasis can be given to those aspects of the existing environment that are driving the development of alternatives for the DMNP. The second section describes the remaining components of the natural environment: fish and fish habitat, terrestrial vegetation, and wildlife. The third section addresses components related to soils and groundwater contamination. The final section describes socio-economic components: land use, air quality and noise, archaeology, aboriginal interests, and built heritage. 3.1 River Characteristics in the Project and Impact Assessment Study Areas The Don Watershed possesses a dendretic drainage pattern that flows southward for 38 kilometres (as the crow flies) from the Oak Ridges Moraine (ORM) to the Inner Harbour of Toronto. The Don possesses two major branches (the East and West Don), each consisting of many smaller sub-watershed systems, such as but not limited to Taylor Massey Creek, Wilket Creek, Patterson Creek and Pomona Creek. The confluence of the East and West Branches occurs approximately 6 kilometres upstream of the Impact Assessment Study Area. Downstream from the confluence, the sub-watershed is known as the Lower Don and includes all of the Don Narrows until reaching the Keating Channel. The entire watershed area or drainage basin of the Don River is approximately 360 square kilometres (Figure 3−1). -
The Fish Communities of the Toronto Waterfront: Summary and Assessment 1989 - 2005
THE FISH COMMUNITIES OF THE TORONTO WATERFRONT: SUMMARY AND ASSESSMENT 1989 - 2005 SEPTEMBER 2008 ACKNOWLEDGMENTS The authors wish to thank the many technical staff, past and present, of the Toronto and Region Conservation Authority and Ministry of Natural Resources who diligently collected electrofishing data for the past 16 years. The completion of this report was aided by the Canada Ontario Agreement (COA). 1 Jason P. Dietrich, 1 Allison M. Hennyey, 1 Rick Portiss, 1 Gord MacPherson, 1 Kelly Montgomery and 2 Bruce J. Morrison 1 Toronto and Region Conservation Authority, 5 Shoreham Drive, Downsview, ON, M3N 1S4, Canada 2 Ontario Ministry of Natural Resources, Lake Ontario Fisheries Management Unit, Glenora Fisheries Station, Picton, ON, K0K 2T0, Canada © Toronto and Region Conservation 2008 ABSTRACT Fish community metrics collected for 16 years (1989 — 2005), using standardized electrofishing methods, throughout the greater Toronto region waterfront, were analyzed to ascertain the current state of the fish community with respect to past conditions. Results that continue to indicate a degraded or further degrading environment include an overall reduction in fish abundance, a high composition of benthivores, an increase in invasive species, an increase in generalist species biomass, yet a decrease in specialist species biomass, and a decrease in cool water Electrofishing in the Toronto Harbour thermal guild species biomass in embayments. Results that may indicate a change in a positive community health direction include no significant changes to species richness, a marked increase in diversity in embayments, a decline in non-native species in embayments and open coasts (despite the invasion of round goby), a recent increase in native species biomass, fluctuating native piscivore dynamics, increased walleye abundance, and a reduction in the proportion of degradation tolerant species. -
Sec 2-Core Circle
TRANSFORMATIVE IDEA 1. THE CORE CIRCLE Re-imagine the valleys, bluffs and islands encircling the Downtown as a fully interconnected 900-hectare immersive landscape system THE CORE CIRLE 30 THE CORE CIRLE PUBLIC WORK 31 TRANSFORMATIVE IDEA 1. THE CORE CIRCLE N The Core Circle re-imagines the valleys, bluffs and islands E encircling the Downtown as a fully connected 900-hectare immersive landscape system W S The Core Circle seeks to improve and offer opportunities to reconnect the urban fabric of the Downtown to its surrounding natural features using the streets, parks and open spaces found around the natural setting of Downtown Toronto including the Don River Valley and ravines, Lake Ontario, the Toronto Islands, Garrison Creek and the Lake Iroquois shoreline. Connecting these large landscape features North: Davenport Road Bluff, Toronto, Canada will create a continuous circular network of open spaces surrounding the Downtown, accessible from both the core and the broader city. The Core Circle re- imagines the Downtown’s framework of valleys, bluffs and islands as a connected 900-hectare landscape system and immersive experience, building on Toronto’s strong identity as a ‘city within a park’ and providing opportunities to acknowledge our natural setting and connect to the history of our natural landscapes. East: Don River Valley Ravine and Rosedale Valley Ravine, Toronto, Canada Historically, the natural landscape features that form the Core Circle were used by Indigenous peoples as village sites, travelling routes and hunting and gathering lands. They are regarded as sacred landscapes and places for spiritual renewal. The Core Circle seeks to re-establish our connection to these landscapes. -

February 11, 2020 Port Lands Flood Protection Project Background for the Canadian Energy Regulator (CER) Waterfront Toronto All text information and images are confidential and cannot be shared. 1 Existing TNPI Pipeline Locations TNPI Abandonment and Removal Applications TNPI has submitted applications to CER for the removal of one deactivated pipeline (Phase 1) and for the abandonment and removal of another deactivated pipeline (Phase 2). History and Context Insert map from The Port Lands Flood Port Lands 101 Protection Project (PLFP) occupies a 290 acre context board footprint in downtown Toronto and involves the creation of a new mouth of the Don River to alleviate flooding, raising of grades, rebuilding of roads with upgraded utilities to support the redevelopment of this former industrial Brownfield. 5 Infilling of the Don River marshlands to create the Keating Channel 6 The goal was to establish an industrial port in Toronto to support economic development 7 Over time the primary industrial activities in the Port Lands transitioned from coal storage and distribution and foundries to light manufacturing and petroleum hydrocarbon refining, storage and distribution. Currently it is comprised largely of sparsely used, derelict Brownfield land. 8 The area outlined in blue represents the flooding that is modeled to occur during a “regulatory flood event”. The PLFP project eliminates this flooding, protecting existing homes and businesses and unlocking the remaining underutilized lands for development as new mixed use residential communities. The area west of the Don River was removed from the West Don Lands Flood Protection Landform floodplain by the construction of the West Don Lands Flood Protection Landform in 2010-2013. -

Zechner Professional Corporation July 2012 Table of Contents 1.0 Executive Summary 5 2.0 Introduction 6 3.0 Eglinton Crosstown LRT Project Description 7 4.0 Soil and Fill Placement/Disposal Options 8 5.0 Estimated Impacts of the Need to Export Excess Soils from the Eglinton Crosstown LRT Project 9 6.0 Conclusions 11 Appendix A: ReNew Canada Ads 12 Endnotes 14 4 rccao.com 1.0 Executive Summary xpanding vital infrastructure to meet the needs of a growing economy and population, as well as the need to replace aging infrastructure components, indicates that the quantity E of excess construction soil is likely to increase greatly in coming years.* The Residential and Civil Construction Alliance of Ontario (RCCAO) is concerned about the growing costs, liabilities, and administrative burdens associated with managing excess construction soils from Ontario construction sites. As municipalities increase restrictions or introduce bans on the importation of fill and soil from outside of their jurisdictions, higher transport costs and increased greenhouse gas emissions will be experienced as a result of longer distances to transport excess construction soils. Costs will further increase as the number of locations that accept these soils declines. Thus analysis focuses on a major construction project to demonstrate the potential impacts on the management of excess construction soils. -
Restrictions on Dredging Activities
Toronto & Region Remedial Action Plan BUI Status Re-designation Document: Restrictions on Dredging Activities January 30, 2014 Draft For additional copies of this report please contact: Toronto and Region Conservation Authority 5 Shoreham Drive Toronto, ON M3N 1S4 www.trca.on.ca phone: (416) 661-6600 ext. 5576 fax: (416) 661-6898 The Toronto and Region Remedial Action Plan is managed by representatives from Environment Canada (EC), Ontario Ministry of the Environment (MOE), Ontario Ministry of Natural Resources and Toronto and Region Conservation Authority. Introduction In 1985, based on recommendations from U.S. and Canadian federal governments, the Great Lakes states and the Province of Ontario, the International Joint Commission (IJC) identified 42 (later 43) areas in the Great Lakes where contaminant concerns existed. These "Areas of Concern" (AOCs) formed the priority sites for environmental actions. The original listing of AOCs was based on a list of 14 designated beneficial use impairments (BUIs). The BUIs noted the major environmental impairments in each of the AOCs, and identified the issues that would need to be addressed for the area to be delisted as an AOC. In many of these areas, contaminated sediments were identified as one of the causes of the use impairments and a number of the BUIs related directly to contaminated sediment issues: Degradation of benthos; Restrictions on fish and wildlife consumption; Fish tumours or other deformities; Bird or animal deformities or reproduction problems; and Restrictions on dredging activities. This report summarizes the rationale for re-designating the “restrictions on dredging” beneficial use within the Toronto and Region Area of Concern from impaired to not impaired. -
