OK, good at North American history, how are you at North American geography?
According to
Wikipedia:
"Although parts of Vancouver Island and parts of Eastern Canada are located south of the 49th parallel, and parts of the United States (Alaska, Northwest Angle) are located north of it, the term 49th parallel is sometimes used metonymically to refer to the entire Canada-U.S. border. This can be misleading, since many of Canada's most populated regions (and about 72% of the national population) are located south of the 49th parallel, including the two largest cities Toronto (43°42' north) and Montreal (45°30' north), the federal capital Ottawa (45.25° north) and the capital cities of all provinces except the Prairie provinces (Alberta, Saskatchewan and Manitoba), these being the only three provinces entirely north of the 49th parallel. The three Maritime provinces are each located entirely south of the parallel; however, the vast majority of Canadian territory lies north of it."
But never mind, I knew what you meant.
