You don't want to get caught on by the Canadian border patrol, unless you called in to the
Canadian customs to register your boat and people in the boat. You must also have a navigational map of the waters your boating on, no mater it you have a couple GPS's on the boat. A friend of mine did not do any of the above, his boat was confiscated and had to pay a 2500.00 fine in order to get his boat and equipment back.
