Ontario is Canada's second-largest province, and the most populous, with more than 14 million inhabitants. It is home to the Canadian capital city of Ottawa, and Toronto, which is Ontario's capital and Canada's largest city. Stretching from the shores of Hudson Bay (an arm of the Arctic Ocean) in the north to four of the five Great Lakes in the South and from Manitoba in the west to Quebec in the east, Ontario is truly massive at over a million square kilometres (almost half a million square miles).
