I agree with KF. You can't just willy-nilly go back & forth crossing borders. You could however, start in Canucks at PP, figure how many nights you will be In Canucks, then have a remote entry (from Canada) permit for the remainder of your trip in MN. You will need an RABC and Canadian fishing liscence, pay the rent for using their land, as well as the BWCAW permit and MN fishing liscence. Don't forget to stop and see Barney in Ely...at end of trip.

As others have said, your canoe will need a current liscence.
