Mandate and Responsibilities

The mission of the Toronto and Region Conservation Authority (TRCA) is to work with its partners to ensure that The Living CityTM is built upon a natural foundation of healthy rivers and shorelines, greenspace and biodiversity, and sustainable communities.

Its area of jurisdiction is comprised of nine watersheds and includes the region’s river valleys, Lake Ontario shoreline, headwater areas of the Oak Ridges Moraine, and the Niagara Escarpment, as the major resources to which its programs are applied. Since its formation in 1957, the Conservation Authority has developed and delivered programs to further the conservation, restoration, development and management of the natural resources within its watersheds.

The TRCA is the largest landowner (15,000 hectares) in the GTA region, and it makes its lands available to the community for outdoor and conservation education, recreation and historic site purposes.

TRCA is governed by the Ontario Conservation Authorities Act and the Ontario Clean Water Act.

The TRCA is responsible for setting strategic policy and for overseeing the business and affairs of the TRCA. To carry out its responsibilities, the TRCA elects an Executive Committee and a Budget/Advisory Board to make recommendations on specific matters.  The TRCA has delegated some of the day-to-day management decisions to its Executive Committee, including the administration of TRCA’s Fill, Construction and Alteration to Waterways Regulation.
