  • Historical Settlement
    HISTORICAL SETTLEMENT CHAPTER 3 The period of historical settlement in the Highland Creek watershed began in about 1650 when aboriginal populations first made contact with European explorers and settlers. A major landmark on the north shore of Lake Ontario, the Scarborough Highlands lent their name to the creek immediately below them from the beginning. Its Mississauga name of “Yat.qui.I.be.no.nick”, recorded in 1796, and all subsequent names reflect its geographical position as the first creek below the high land. Travellers going westward on the lake would often camp at the mouth of the Highland Creek rather than attempt a passage along the base of the Bluffs in darkness or bad weather. The following sections provide an overview of the historical period including contact between aboriginal and Euro-Canadian peoples, key characteristics of the successive periods of settlement, the impact of this settlement on the environment, and a summary of heritage resources found in the watershed. 3.1 CONTACT 1650 TO 1800 Following the decimation and ultimate dispersal of the Petun and Huron by the Iroquois in 1650, southern Ontario was uninhabited for a few years before the Iroquois moved into the area to establish a number of large villages along the north shore of Lake Ontario for the exploitation of the local fur resources. One such village was Ganatsekiagon, located on the Rouge River. No villages of this size and importance have been found in the Highland Creek watershed, but evidence shows that the resources of Highland Creek were used by the native peoples of these villages.

  • 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.

    Humber River FFiisshheerriieess MMaannaaggeemmeenntt PPllaann A cooperative resource management plan developed by the Ontario Ministry of Natural Resources and the Toronto and Region Conservation Authority October 2004 Correct citation for this publication: Clayton, J., Hayes K., Heaton, M. G. and, Lawrie, D. 2004. Humber River Fisheries Management Plan. Published by the Ontario Ministry of Natural Resources and the Toronto and Region Conservation Authority. i PREFACE A number of federal, provincial and regional strategies exist to guide watershed management and habitat protection and rehabilitation. At a federal level, the Toronto and Region Remedial Action Plan (RAP) was established in accordance with the Canada-United States Great Lakes Water Quality Agreement and identified the Toronto and Region Area of Concern (AOCs) as one of 43 AOCs around the Great Lakes. The Stage I RAP document identifies types and sources of water pollution problems, and outlines goals, remedial actions, agencies, costs, timetables and monitoring programs. Stage II provides a framework for guiding more local initiatives, such as fisheries rehabilitation. The Humber River Fisheries Management Plan (FMP) provides direction on three RAP goals and actions: Goal 2a) a self sustaining fishery Goal 2b) rehabilitation of fish and wildlife habitat Action 21) protect and restore fish and wildlife habitat Implementation of RAP recommendations, in conjunction with the recommendations of watershed based rehabilitation plans, will eventually lead to the delisting of watersheds within the Toronto and Region Area of Concern. Provincial fisheries management plans that set the context for the Humber River Fisheries Management Plan include the Strategic Plan for Ontario Fisheries (SPO F II) and the Maple District Fisheries Management Plan.

  • Humber River State of the Watershed Report – Surface Water Quantity
    Humber River State of the Watershed Report – Surface Water Quantity 2008 Humber River State of the Watershed Report – Surface Water Quantity EXECUTIVE SUMMARY • As of 2002, only one quarter (25%) of the total urban area in the Humber River watershed had stormwater management controls in place to treat urban run-off prior to it being released to receiving watercourses. • The majority of annual stream flow in both the Main and East Humber subwatersheds is generated by groundwater discharge (baseflow) due to the permeable soils and hummocky terrain of the Oak Ridges Moraine area, predominantly rural land uses and presence of aquifers. • The Oak Ridges Moraine, particularly its southernmost extent, and the Iroquois Sand Plain are major influences on the distribution of baseflow in the watershed. Both of these physiographic regions are characterized by highly permeable soils and underlying geology (sand and gravel) which produce high rates of infiltration and groundwater discharge to streams. • Half (50%) of the total stream flow in the Humber River during baseflow conditions originates from within the Main Humber and East Humber subwatersheds. Secondary subwatersheds observed to be major contributors to baseflow are Upper Main, Centreville Creek and Purpleville Creek. • Baseflows in the West Humber subwatershed are low with large tributaries becoming dry during summer months. The majority of stream flow is generated by surface run-off due to low permeability soils, impervious surfaces, and in some areas no aquifers being present. • The majority of baseflow in the West Humber originates from the west branch. • Seasonal variations in baseflow and minimum sustained baseflow rates at long term stream gauge sites have not changed significantly since continuous monitoring began in the late 1950s.

  • Highland Creek Village Transportation Master Plan
    REPORT FOR ACTION Highland Creek Village Transportation Master Plan Date: April 14, 2021 To: Infrastructure and Environment Committee From: General Manager, Transportation Services Wards: Ward 25 - Scarborough-Rouge Park SUMMARY Highland Creek Village is located in south-east Scarborough. The Village was one of the first neighbourhoods established in Scarborough. Today there is a mix of commercial, residential and institutional uses in the Village. There are a number of active development applications in the area, primarily along Old Kingston/Kingston Road and Military Trail presenting opportunities to secure some transportation improvements in the area through the development review process. The area’s transportation network consists of highway, arterial, collector and local roads, bounded on the south and north by Highway 2A and Kingston Road/ Old Kingston Road, and between Military Trail in the west and Meadowvale Road in the east. Key issues with the transportation network include: • poor active transportation options; • angled and minimal on-street parking; and • unconventional road network connections to support future development. In 2012, City Council directed Transportation Services to undertake an Environmental Assessment (EA) in the area as part of its decision on the Highland Creek Village Area Study (Area Study) - Final Report to review the feasibility of changes to the area’s road network. This report summarizes the outcomes of the Transportation Master Plan (TMP) process undertaken under the Municipal Class EA (MCEA) process to consider transportation and servicing infrastructure needs in the Highland Creek Village area to support current and longer-term redevelopment of the area. Additional objectives for the TMP are to attract investment to the community and improve the area’s various streetscapes, consistent with the vision for the area.
