Considering how inconvenient it is in some geographies and how small the patches of land are, I'm always surprised the State Department doesn't negotiate a land exchange treaty with Canada to fix what are essentially cartography bugs.
Both sides would spend a few tens of millions compensating people for land seizures and dealing with the administrative overhead of negotiating and ratifying the deal but would gain it back over time with simplified border stations.
