Usually there are a lot of Canadians here in the winter. This year, Covid regulations in their own country don’t allow them to cross the border to their less-responsible neighbors to the south though. They want to keep the brakes on their outbreaks.
So we were surprised when Canadians showed up here this winter. We were glad to see them, but curious. We asked. Turns out, Canadians can’t cross the border from their country to ours. They can’t walk, drive, or take a bus. They can, however, fly, so they’re here. Does that make sense? You can’t cross the border on the ground, but you can fly. I hope the rules work in reverse for them; that flying back to Canada from the U.S. is not a problem either.
