June 24, 2022 - Update on the Ganaraska Forest Closure

GRCA staff continued to clear primary and secondary Forest roads within the West and Central Forest. Downed trees along with dangerous spring poles and cracked trees do slow efforts.

The Ganaraska Forest remains closed. Trees and hangers continue to come down as addition storm systems occur in the area. The GRCA thanks everyone for their patience and understanding.

Please note: Existing memberships will be extended to reflect the closure period.

The GRCA is asking for people to PLEASE stay away from the area.

Updates will be provided as they become available. Your understanding and patience is appreciated!


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.
