  • 3. Description of the Potentially Affected Environment
    ENVIRONMENTAL ASSESSMENT 3. Description of the Potentially Affected Environment The purpose of Chapter 3 is to present an overview of the environment potentially affected by the SWP to create familiarity with issues to be addressed and the complexity of the environment likely to be affected by the Project. All aspects of the environment within the Project Study Area (see Figure 2- 1 in Chapter 2) relevant to the Project and its potential effects have been described in this chapter. The chapter is divided into three sections which capture different components of the environment: 1. Physical environment: describes the coastal and geotechnical processes acting on the Project Study Area; 2. Natural environment: describes terrestrial and aquatic habitat and species; and, 3. Socio-economic environment: describes existing and planned land use, land ownership, recreation, archaeology, cultural heritage, and Aboriginal interests. The description of the existing environment is based on the information from a number of studies, which have been referenced in the relevant sections. Additional field surveys were undertaken where appropriate. Where applicable, future environmental conditions are also discussed. For most components of the environment, existing conditions within the Project Area or Project Study Area are described. Where appropriate, conditions within the broader Regional Study Area are also described. 3.1 Physical Environment Structures and property within slopes, valleys and shorelines may be susceptible to damage from natural processes such as erosion, slope failures and dynamic beaches. These processes become natural hazards when people and property locate in areas where they normally occur (MNR, 2001). Therefore, understanding physical natural processes is vital to developing locally-appropriate Alternatives in order to meet Project Objectives.

  • Toronto Has No History!’
    ‘TORONTO HAS NO HISTORY!’ INDIGENEITY, SETTLER COLONIALISM AND HISTORICAL MEMORY IN CANADA’S LARGEST CITY By Victoria Jane Freeman A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of History University of Toronto ©Copyright by Victoria Jane Freeman 2010 ABSTRACT ‘TORONTO HAS NO HISTORY!’ ABSTRACT ‘TORONTO HAS NO HISTORY!’ INDIGENEITY, SETTLER COLONIALISM AND HISTORICAL MEMORY IN CANADA’S LARGEST CITY Doctor of Philosophy 2010 Victoria Jane Freeman Graduate Department of History University of Toronto The Indigenous past is largely absent from settler representations of the history of the city of Toronto, Canada. Nineteenth and twentieth century historical chroniclers often downplayed the historic presence of the Mississaugas and their Indigenous predecessors by drawing on doctrines of terra nullius , ignoring the significance of the Toronto Purchase, and changing the city’s foundational story from the establishment of York in 1793 to the incorporation of the City of Toronto in 1834. These chroniclers usually assumed that “real Indians” and urban life were inimical. Often their representations implied that local Indigenous peoples had no significant history and thus the region had little or no history before the arrival of Europeans. Alternatively, narratives of ethical settler indigenization positioned the Indigenous past as the uncivilized starting point in a monological European theory of historical development. i i iii In many civic discourses, the city stood in for the nation as a symbol of its future, and national history stood in for the region’s local history. The national replaced ‘the Indigenous’ in an ideological process that peaked between the 1880s and the 1930s.

    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).

  • 2020 Year in Review
    2020 Year in Review Ed Hore, Chair, Waterfront for All, February 10, 2021 Waterfront for All is an umbrella group of residents associations and other groups interested in the revitalization of the Toronto waterfront from the Rouge River in the east out to the Etobicoke boundary in the west. We love the waterfront and are interested in what happens to it. Here’s a brief run-down on things that happened in 2020. Water Levels Before the pandemic, a major concern along the waterfront was whether 2020 would bring flooding as happened in 2019 and 2017. There was a well-attended meeting about this at the Brigantine Room at Harbourfront on March 3, 2020, attended by politicians and hundreds of residents. This was the last crowded big meeting I went to before Covid shut-down public meetings. In early 2020, Toronto and Region Conservation Authority (TRCA) carried out some quick projects on Toronto Island to alleviate the effects of future floods. For example, they built “beach curbs” east and west of the Ward’s Island ferry dock. These consist of rectangular stones weighing three to five tonnes laid end to end to provide some protection if the water rises. The beach curbs were in place by the end of March. TRCA also raised some sections of the roadway from Wards to Hanlans Point around six inches, so that emergency vehicles could get through in the event of a flood. But in fact no flood happened; the water level of Lake Ontario peaked on May 5, 2020, around 20 inches lower than the peak level in 2019.

  • Paradise Lost
    PARADISE LOST AFTER THE FLOOD; CAN TORONTO ISLANDS BE SAVED FROM THE NEXT DISASTER? The island flood of 2017 is a clear warning that we must do all we can to ­preserve the closest thing to wilderness that we have in Toronto BY RICHARD LONGLEY SEPTEMBER 13, 2017 IMAGES BY SEAN TAMBLYN NOW MAGAZINE Seneca­Pump The flood waters had only begun to subside, but over the August long weekend, the Ward’s Island Association annual Summer Gala was in full swing beside the Ward’s Island Clubhouse. The band played, and attendees wore T-shirts that read “I Survived the Flood of 2017.” “We laughed, we drank beer on the bowling green,” says long-time Island resident Jay Bascom. “We’d survived adversity in the past and we knew we could survive it again.”A veteran of the floods of 1952, 1973, 1993 and 2017 – as well as the “40 years war” waged by the former Metro Council to evict Island residents – Bascom is a living testament to the resilience of the Toronto Islanders. For the 20,000 people who visit them on sunny summer weekends, the Toronto Islands are a lotus land of meadows, woods, lagoons and sandy beaches (one of them clothing optional). But for the 800 residents, 30 businesses and two schools that call the islands home, it isn’t always paradise. The weather can blast, flood and ice them in from the mainland. The land they live on is nothing more than a bump in a watery sandbox that’s slowly sinking out from under itself.

  • Introduction
    Introduction canadian classical pianist Glenn Gould once said that Toronto was one of the few cities in the world in which he could live because it imposed no “cityness” upon him. This statement may seem somewhat curious, given that at the time of its utterance Toronto was a rapidly growing conurbation of over two million people, with suburbs that radiated out in all directions from a busy central core. Yet perhaps not. Perhaps Gould’s view was, in part, influenced by where he was raised, Toronto’s Beach, where within a short five or ten minute stroll down a hill, or through a leafy ravine, he could reach the limit of the city and stand along the shore of one of North America’s massive inland seas, Lake Ontario. Though Gould’s favourite place in the Beach was the water’s edge, he also roamed Toronto Bay, tracking the freighters from far-off exotic locales that cruised up the St. Lawrence from the Atlantic Ocean into Lake Ontario, finally arriving at Canada’s great interior maritime city, Toronto. Lieutenant Governor John Graves Simcoe, who visited Toronto Bay in May of 1793, was also attracted to the site but for different reasons: the sandy peninsula in front of the mainland made for a natural shel- tering harbour in the event of an anticipated American attack. Toronto also stood at the junction of two ancient aboriginal transpor- tation corridors: the relatively flat Lakeshore Trail and the Toronto Carrying Place, whose two branches, near the mouths of the Rouge and Humber Rivers, served as access points to the Upper Great Lakes and the interior regions of Canada.

    What’s Out There? Toronto - 1 - What’s Out There - Toronto The Guide The Purpose “Cultural Landscapes provide a sense of place and identity; they map our relationship with the land over time; and they are part of our national heritage and each of our lives” (TCLF). These landscapes are important to a city because they reveal the influence that humans have had on the natural environment in addition to how they continue to interact with these land- scapes. It is significant to learn about and understand the cultural landscapes of a city because they are part of the city’s history. The purpose of this What’s Out There Guide-Toronto is to identify and raise public awareness of significant landscapes within the City of Toron- to. This guide sets out the details of a variety of cultural landscapes that are located within the City and offers readers with key information pertaining to landscape types, styles, designers, and the history of landscape, including how it has changed overtime. It will also provide basic information about the different landscape, the location of the sites within the City, colourful pic- tures and maps so that readers can gain a solid understanding of the area. In addition to educating readers about the cultural landscapes that have helped shape the City of Toronto, this guide will encourage residents and visitors of the City to travel to and experience these unique locations. The What’s Out There guide for Toronto also serves as a reminder of the im- portance of the protection, enhancement and conservation of these cultural landscapes so that we can preserve the City’s rich history and diversity and enjoy these landscapes for decades to come.

  • The Islands Were Originally a 9 Kilometer (5.6 Mi) Long Peninsula Or Sand Spit Extending from the Mainland
    1 • The islands were originally a 9 kilometer (5.6 mi) long peninsula or sand spit extending from the mainland. The islands are composed of alluvial deposits from the erosion of the Scarborough Bluffs. • By 1850 these sand bars had grown by 12 ha. A severe storm in April of 1858 separated the peninsula from the mainland forming what is now known as the Eastern Gap. • The channel was widened and made permanent following the 1858 storm. The channel became known as the Eastern Gap.The peninsula to the west became known as the Toronto Islands. • In recent decades, the creation of the Leslie Street Spit as well as other shoreline alterations have resulted in a significant change in the historic transport processes responsible for the creation and maintenance of the Island. 2 • Strong winds, such as those from the south west, generate significant wave action that buffet Gibraltar Point and result in erosion of the shoreline • This eroded material is pulled away from the shoreline via cross‐shore transport, or undertow, and then transported northwestward where they are deposited in and around Hanlan’s Beach. 3 • The effects of erosion have widespread implications for the island. • Recreationally, the south western shore of the islands are home to some of Toronto’s cleanest beaches, which rely on erosion at Gibraltar Point to stay nourished with sand. Changes at Gibraltar point thus will have direct impacts on Hanlan’s Beach. • Some of Lake Ontario’s most diverse and productive fish habitat are found within the Islands inner ponds. If erosion is allowed to continue unabated, these ponds may become exposed directly to Lake Ontario in several decades, which will have profound changes on these fish communities.

  • An Aesthetics for the Leslie Street Spit by Alexander Chan A
    Sympathetic Landscapes: an aesthetics for the Leslie Street Spit by Alexander Chan A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Architecture Waterloo, Ontario, Canada, 2013 © Alexander Chan 2013 I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii ABSTRACT The Leslie Street Spit is a five kilometre rubble breakwater on the eastern waterfront of Toronto. Built during the mid-twentieth-century as an infrastructural add-on to the existing Port Lands Industrial District, the artificial peninsula was a lakefilling project made to realize the city’s ambitious desire for economic prosperity and world-class prestige by expanding its existing harbour facilities. With the decline of Toronto’s shipping industry, the Leslie Spit remained an active dump site for urban clean fill until it was unexpectedly colonized by flora and fauna during the 1970s. The site is now recognized as an important local and international environmental resource. Visitors to the Leslie Spit experience a diverse landscape of ecosystems and industrial rubble helded by the city as a symbol of environmental revival within a former industrial region undergoing another phase of urbanization. While the local aesthetic experience of the headland is pleasurable and aligns with the reinvention of Toronto as am environmentally conscious and sustainable city, human visitors remain psychologically and physically removed from the inhabiting non-human life.
