"It’s worth noting that any watercraft that is fitted with a motor is considered to be a motorized vessel and you need an operator’s card if you plan to be on the water in one. This includes canoes with electric trolling motors or small gasoline engines, sailboats that have auxiliary engines (whether the engine is in use or not), personal watercraft, boats powered solely by electric motors and others. In short, if it floats and has a motor on it, you need a card in order to legally operate it."
