Toronto is the most populous city in Canada and the provincial capital of Ontario. It is located in Southern Ontario on the northwestern shore of Lake Ontario. As Canada's economic capital, Toronto is considered a global city and is one of the top financial centres in the world. Toronto's population is cosmopolitan and international, and the many residential communities of the city express a character distinct from that of the skyscrapers in the commercial core. It is a major scene for theatre and other performing arts, and is home to the CN tower, the tallest free-standing land structure in the world at 553 metres (1,810 ft), The Royal Ontario Museum (ROM);a major museum for world culture and natural history, and The Toronto Zoo, one of the largest in the world.
