Canada is actually south of what U.S. city?

Canada is actually south of Detroit, Michigan. The surprising fact comes from Windsor, Ontario, which sits across the Detroit River and slightly south of Detroit’s downtown.

Windsor is Canada’s southernmost major city and occupies the southwestern tip of Ontario. Its position is shaped by the Great Lakes: the Detroit River runs roughly north–south between the two cities, while Lake Erie lies south of both. On a typical north-up map, Windsor appears below Detroit, even though it is in Canada.

The border’s unusual shape often causes confusion. Many people assume Canada must be north of every part of the United States, but the international boundary follows rivers, lakes, and surveyed lines—not a perfect east–west latitude. Windsor and Detroit form one of North America’s most prominent cross-border urban areas, linked by the Ambassador Bridge and the Detroit–Windsor Tunnel.

A related pop-culture mix-up comes from the phrase “South Detroit” in Journey’s song “Don’t Stop Believin’.” There is no official city or neighborhood called South Detroit in the usual sense; the lyric is commonly joked about because Windsor, Canada, is geographically south of Detroit.
