About Us

The Lake Simcoe Region Conservation Authority

The Lake Simcoe Region Conservation Authority (LSRCA) is a local watershed management organization, incorporated under the Conservation Authorities Act (1946).

Since 1951, we have been dedicated to conserving, restoring and managing the Lake Simcoe watershed​.

Our jurisdiction, which began in the East Holland River with five municipalities, has grown to include the entire Lak​e Simcoe watershed with the exception of the City of Orillia and the Upper Talbot River subwatershed.

We are governed by an 18-member Board of Directors, appointed within a four-year cycle by its 9 member municipalities. Each year, the Board of Directors elects a Chair and Vice Chair from among its 18 members.



Healthy lake, healthy land, healthy life… for generations to come.


We collaborate to protect and restore the Lake Simcoe watershed with innovative research, policy and action.
