Supplemental Information

Funding for this study was provided in part by the Government of Canada’s Great Lakes Action Plan (GLAP) and in support to Toronto and Region Area of Concern.

In 1987 under the revised Great Lakes Water Quality Agreement, 43 areas of concern (AOC), 12 of which are located in Canada, were identified as having severely impaired beneficial uses and water quality. As funded by the Great Lakes Action Plan, a Remedial Action Plan was formed for each area of concern bringing together experts from government, industry, municipalities and environmental non-government organizations to address these impacts. Today over 900 restoration projects have been successfully completed by Environment and Climate Change Canada and partners including Wastewater Treatment Plant upgrades, fish and wildlife habitat restoration, and water quality improvements
