Good Neighbours

While the 49th parallel is often thought of as the border between the US and Canada, the vast majority of Canadians (roughly 72%) live below it, with 50% of Canadians living south of 45°42′ (45.7 degrees) north or the red line above.

Toronto (43°42′N) and Montreal (45°30′N), Canada’s biggest and second biggest cities respectively, both lie just below the line as does Ottawa (45°25′N), the capital and 4th largest city.
