  • 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.

  • Disrupting Toronto's Urban Space Through the Creative (In)Terventions
    CORE Metadata, citation and similar papers at core.ac.uk Provided by Institutional Repository of the Ibero-American Institute, Berlin Disrupting Toronto’s Urban Space through the Creative (In)terventions of Robert Houle Alterando el espacio urbano de Toronto a través de las (in)tervenciones creativas de Robert Houle Julie Nagam University of Winnipeg and Winnipeg Art Gallery, Canada [email protected] Abstract: is essay addresses the concealed geographies of Indigenous histories in the City of Toronto, Canada, through selected artworks that address history, space, and place. e research is grounded in the idea that the selected artworks narrate Indigenous stories of place to visually demonstrate an alternative cartography that challenges myths of settlement situated in the colonial narratives of archaeology and geography. Indigenous artist Robert Houle has created artworks that narrate Indigenous stories of place using the memories and wisdom of Indigenous people in areas of art, archaeology, and geography (land). is visual map is grounded in the premise that the history of the land is embodied in Indigenous knowledge of concealed geographies and oral histories. It relies upon concepts of Native space and place to demonstrate the signicance of the embodied knowledges of Indigenous people and highlights the importance of reading the land as a valuable archive of memory and history. Keywords: Indigenous; art; geographies; space; urban; Toronto; Canada; 20th-21st centuries. Resumen: Este ensayo aborda las geografías ocultas de las historias indígenas en la ciudad de Toronto, Canadá, a través de obras de arte seleccionadas que abordan la historia, el espacio y el lugar. La investigación se basa en la idea de que las obras seleccionadas narran historias de lugar indígenas para mostrar visualmente una cartografía alternativa que desafía los mitos de asentamiento situados en las narrativas coloniales de la arqueología y la geografía.

  • 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.

  • AECOM Report 1.Dot
    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).

These shared concerns include the environment, land use, housing, social services, and much more, and modern municipalities do make attempts to address Indigenous-specific needs in these areas; but Indigenous-municipal relationships have implications that far exceed the technocratic and siloed ways in which Canadian systems generally approach these broad areas of concern - implications not only with regard for Indigenous people, but for all people.

  • 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.
