Most provinces have a riding federation. Under the umbrella of this organization you will find the local riding clubs. Joining a club is a great way to get started off road. Many of the clubs have orientation days to teach you the rules of riding, to introduce you to new friends and to show where you can legally ride. The list of the organizations are as follows;
Motorcyclists Confederation of Canada
British Columbia Off-Road Motorcycle Association
Alberta Off-Highway Vehicle Association
Ontario Federation of Trail Riders
Fédération Québécoise des Motos Hors Route
