Yes, but they're not majorities in the region. Population has become rather diluted.
Says here there are over 14,000 people of Finnish descent in Thunder Bay, and in some counties in the UP, the largest ancestry group are Finns. Plus in Chile up to 20% of the population has Basque origins, and they form a noted part of the (at least historic) social elite, so there's likely some very "pure" strains of Basque ancestry there.
