US and Canada

The video referenced likely comes from an educational or trivia source discussing Canada-U.S. border geography. It claims 70-72% of Canadians live south of the 49th parallel, Canada's southernmost point (Middle Island, 41.68°N) is south of parts of 27 U.S. states, and traveling south from Detroit enters Canada. These points are mostly accurate, though the video may misstate the number of states (27, not 16). I couldn't pinpoint the exact source, but it aligns with geographical facts from sources like The Globe and Mail and WorldAtlas.
