Toronto is an international centre for business and finance. Generally considered the financial capital of Canada, Toronto has a high concentration of banks and brokerage firms on Bay Street, in the Financial District. The Toronto Stock Exchange is the world’s seventh-largest stock exchange by market capitalization. The five largest financial institutions of Canada, collectively known as the Big Five, have national offices in Toronto. The city is an important centre for the media, publishing, telecommunication, information technology and film production industries; it is home to Bell Media, Rogers Communications, and Torstar. Other prominent Canadian corporations in the Greater Toronto Area include Magna International, Celestica, Manulife Financial, Sun Life Financial, the Hudson’s Bay Company, and major hotel companies and operators, such as Four Seasons Hotels and Fairmont Hotels and Resorts. Although much of the region’s manufacturing activities take place outside the city limits, Toronto continues to be a wholesale and distribution point for the industrial sector. The city’s strategic position along the Quebec City – Windsor Corridor and its road and rail connections help support the nearby production of motor vehicles, iron, steel, food, machinery, chemicals and paper. The completion of the Saint Lawrence Seaway gave ships access to the Great Lakes from the Atlantic Ocean.
