About Toronto

Toronto is Canada’s largest city, and the fourth-largest in North America. Toronto is a global business, entertainment and tourism hub, famous for its progressiveness and diversity. Toronto may be the world’s most global city, with 50 per cent of the population born outside of Canada, and more than 200 languages and dialects are spoken in Toronto.

Toronto sits on the northern shore of Lake Ontario (the easternmost of the Great Lakes) and has a shoreline stretching 43 kilometres featuring sandy beaches, marinas and working ports.

Two major rivers flow through Toronto into Lake Ontario: The Humber River on the west side of the city and the Don River on the east side. Each has tributaries that create a vast ravine system of forests and trails to explore throughout the city.
