If you are under 21, do not drink alcohol in Canada and attempt to return to the United States. You will be apprehended at the border. Canadian Police may legally require proof of automobile insurance written in French as well as English. You can avoid the risk of having your car impounded by purchasing a Canadian rider through your automobile insurance carrier. A Canadian rider is merely proof of insurance card written in French and on the reverse side written in English.
Most insurance carriers provide a Canadian rider for free or at minimal cost.
