Google Maps shows about 90 miles, on a direct line, between Copper Harbor and Thunder bay. About 180 miles to Sault Ste. Marie. Having been in the area many times, Canada does not feel -- and is not, barring I guess an expensive and international sea plane flight -- a day trip. (And yeah, there's one controversial local magnate I'm aware of who would make that trip -- in his own plane.)

It may not be Canada-level wilderness, but it's pretty empty -- or "thin". IIRC, I was told that the large Ontonagon County, towards the west end of the UP, has one of the lowest county population densities in the entire country.
