Ottawa, the capital of Canada, uses the Canadian dollar (CAD) as its official currency. Its symbol is "$" or "C$" to distinguish it from other dollar-denominated currencies. It is issued in the form of coins and banknotes. Coins come in denominations of five, ten, and twenty-five cents, as well as one- and two-dollar coins known as "loonies" and "toonies." Banknotes are issued in denominations of five, ten, twenty, fifty, and one hundred dollars.
