Regulated Area Search
PLEASE NOTE:
We are currently updating our mapping to more accurately reflect the areas that are regulated by TRCA. Use the button below to view the draft updated mapping.
In accordance with Ontario Regulation 166/06, TRCA regulates areas where development could be subject to flooding, erosion or dynamic beaches, and where interference with wetlands and alterations to shorelines and watercourses might adversely affect those environmental features. Any of these activities within the Regulated Area may require a permit from TRCA.
Please use the search tool below to determine if your property is within TRCA’s Regulated Area. Note that mapping is updated on a periodic basis and not all regulated areas may be mapped.
If you would like written confirmation and a more detailed review of how your property may be affected by our regulation and other TRCA policies and programs, consider using TRCA’s property inquiry or other services.
