Toronto, Ontario, the provincial capital of Ontario and one of the largest cities in Canada. It is the chief commercial, industrial, and cultural center in the English-speaking part of Canada.
Toronto is situated on the northwestern shore of Lake Ontario, across from New York State, in one of the most densely populated parts of Canada. Near the lakefront is the central business district, facing a harbor virtually enclosed by islands. Greater Toronto—the city and its suburban area—is the most populous metropolitan area in Canada.
