TRCA Regulated Area
The data depicts regulated areas within the Toronto and Region Conservation Authority (TRCA) area of jurisdiction and is governed by paragraph 2 of subsection 28 (1) of the Conservation Authorities Act and section 4 of Ontario Regulation 41/24: Prohibited Activities, Exemptions and Permits. Some regulated features may not appear in the data. In the case of a conflict, the description of regulated areas in the Act and the Regulation prevails over the depiction of the areas. For more information, please contact TRCA at [email protected]
Last Update Date: April 28, 2026
Not all regulated areas may be mapped. Boundary lines are a conceptual representation of TRCA's Regulation limit and should not be relied upon as a precise delineation. A feature or hazard does not have to be mapped to be regulated. See text of the Conservation Authorities Act and Ontario Regulation 41/24 for details.
