Lake Ontario Waterfront

SHORELINE HAZARD WARNING IS IN EFFECT

Updated: May 6, 2019

Toronto and Region Conservation Authority (TRCA) is warning of shoreline erosion along the waterfront in its jurisdiction.

This erosion activity can create washout on the lakeside edge of the trail, potentially compromising the edges of the paths and posing a risk to users. This washout is not always visible to users standing on the trail if water levels or waves are high.

TRCA cautions members of the public who walk along the shoreline and waterfront trail. Signs have been posted in areas where access is temporarily being prohibited for your safety and due to construction activity.

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.
