One of the oddities of the Detroit area is that part of the city of Detroit is actually north of the Canadian city of Windsor.
There is another small area of Canada that has an island south of the northern-most point in Washington. That's because when the 49th parallel was selected for the western part of the border, it just happened to include the lower part of this piece of land that put a few square miles in the U.S.
Point Roberts is a little piece of land that can only be reached by boat directly from another point in the U.S. Otherwise, you have to drive through Canada to get there.
Then there is one little strip of land between Lake Ontario and Lake Erie where Canada meanders a little south of U.S. territory.
So, this little bit of esoteric geography is brought to you with the hope that someday you can find the opportunity to bet someone that Canada is south of the U.S. (excluding Alaska) and win [yeah, it's a technicality, but so what?].
