WHO WE ARE
Since 1957, Toronto and Region Conservation Authority (TRCA), as enabled through the provincial Conservation Authorities Act, has taken action to enhance our region’s natural environment and protect our land, water and communities from the impacts of flooding and increasingly extreme weather events — Ontario’s leading cause of public emergencies.
As the region’s first line of defence against natural hazards, TRCA maintains vital infrastructure and provides programs and services that promote public health and safety, protecting people and property.
TRCA mobilizes a science-based approach to provide sound policy advice, leveraging its position as a not-for-profit operating in the broader public sector to achieve collective impacts within our communities and across all levels of government.
TRCA’s jurisdiction includes nine watersheds and their Lake Ontario shorelines:
- Carruthers Creek
- Don River
- Duffins Creek
- Etobicoke Creek
- Highland Creek
- Humber River
- Mimico Creek
- Petticoat Creek
- Rouge River
The jurisdiction spans the following six upper-tier and 15 lower-tier municipalities, representing almost five million people (approximately 10% of Canada’s population):
