Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver.

The Italian city of Campobasso was known as "Canada City" or in a minor way "Maple Leaf City", since during the Second World War, Canadian troops invaded the city and freed it from the Germans. Moreover, the city has a huge variety of maples which can be found even in the streets.

The U.S. city of Carthage, Missouri is nicknamed "America's Maple Leaf City."
