>>303494It is an American National Park, I would imagine just canoeing over would probably get you in a bit of a bind with customs, since you essentially hopped the boarder. You could call and see if it's even feasible to do so. If not you may need to legally enter the USA and leave from Grand Portage... However IDK if you could even canoe out there and be allowed on the island, either way that'd be one risky canoe trip in the big lake especially if the weather turned on you...
