Toronto and Region Conservation Authority (TRCA) has jurisdiction over 72 kilometres of Lake Ontario waterfront. We are committed to preserving and enhancing the health and beauty of this entire shoreline.
TRCA’s area of jurisdiction on the waterfront extends from the City of Toronto/City of Mississauga border in the west to the Town of Ajax/Town of Whitby border in the east.
Across this shoreline, nine watersheds drain into Lake Ontario: Etobicoke Creek, Mimico Creek, Humber River, Don River, Highland Creek, Rouge River, Duffins Creek, Petticoat Creek, and Carruthers Creek.
The sediment that makes up the Toronto Region shoreline is generally a mixture of sands, silts, clays, tills, and gravels, all of which are highly erodible. As a result, the shoreline has been — and continues to be — modified by wave action, ground water conditions, wind erosion and numerous other factors. Serious loss of property and threats to homes, roads and services can and have occurred as a result of these processes.
TRCA works to maintain shoreline protection and restore terrestrial and aquatic habit along the shoreline, while providing recreational opportunities through the design and construction of waterfront parks. Integrated shoreline management is essential to efforts to achieve a waterfront that is clean, green, accessible, diverse and attractive.
