Contrary to general public belief you currently need a Motorcycle License or a minimum of an M-1 License to operate any motorized 2 wheel vehicle that does not have pedals regardless of the size of engine or motor.

New Regulations are now in place for owners and drivers of Mopeds, Limited Speed Motorcycles and Motorscooters in Ontario.
