Toronto and Region Conservation Authority (TRCA) is one of Ontario’s 36 conservation authorities with the mandate to ensure the conservation, restoration and responsible management of Ontario’s water, land and natural habitats through programs that balance human, environmental and economic needs.

TRCA has six participating municipalities:

  • City of Toronto
  • Regional Municipality of Durham
  • Regional Municipality of Peel
  • Regional Municipality of York
  • Township of Adjala-Tosorontio
  • Town of Mono

TRCA works with its six member municipalities and other partners to further the conservation, restoration, development, and management of natural resources within its jurisdiction which is comprised of nine watersheds in the Toronto Region and the Lake Ontario shoreline. TRCA’s lands (almost 18,000 hectares) are made available to the public for outdoor and conservation education and recreational uses.

Key services and programs developed and delivered by TRCA include flood and erosion risk management, stormwater and watershed management, greenspace management and regulation of planning and development (review and permit approvals) on lands within its jurisdiction.

All six member municipalities contribute to TRCA’s operating and capital budgets. Read TRCA’s 2019 Budget for detailed budget information on TRCA’s service activities.
