Welcome to LSRCA

The Lake Simcoe Region Conservation Authority (LSRCA) has been dedicated to conserving, restoring and managing the Lake Simcoe watershed since 1951.

Thanks to our generous federal, provincial, municipal and community partners, we build on a tradition of success and provide the leadership needed to protect what is natural and restore what has degraded in our watershed.

Our mission is to work with our community to protect and restore the Lake Simcoe watershed by leading research, policy and action.
