Welcome to the Ganaraska Region Conservation Authority

The Ganaraska Region Conservation Authority's overall goal is the conservation, restoration, development and management of natural resources on a watershed basis while providing for the public enjoyment of the lands it oversees.

The Ganaraska Region Conservation Authority (GRCA) was formed in October 1946 under the Conservation Authorities Act and is one of the oldest conservation authorities in Ontario.

The watersheds of the GRCA covers an area of 361 square miles from Wilmot Creek in Clarington to east of Cobourg from the south shore of Rice Lake down to Lake Ontario. This area includes seven municipalities in whole or in part: Township of Cavan-Monaghan, Town of Cobourg, Township of Alnwick-Haldimand, Township of Hamilton, Municipality of Port Hope, City of Kawartha Lakes, Municipality of Clarington.

The Ganaraska Region Conservation Authority (GRCA) and Ganaraska Forest Centre (GFC) will be closed on Thanksgiving Monday. Both locations will reopen on Tuesday, October 9th at 8:30 a.m.

Planning a visit to the Ganaraska Forest? All recreational users must obtain a day pass or membership. Please visit one of our remote locations or use the self-serve option at the GFC Gatehouse.

Happy Thanksgiving!
