Toronto has one of the largest transit systems in all of North America; the only cities with higher daily ridership are Mexico City and New York City. Today, service within Toronto is operated by the Toronto Transit Commission (TTC), which was established in 1954.
Toronto’s transit network is quite diverse, consisting of heavy rail, rapid transit, streetcars, and buses. The subway system has 69 stations on three lines, with extensions under construction at this time. There is also a “rapid transit” line to Scarborough that uses Intermediate Capacity Transit System, similar to the rolling stock on the SkyTrain in Vancouver. Service is very frequent, even outside of peak hours, as most buses just feed the subway and passengers must change to continue downtown.
The streetcar network is the largest in North America. Eleven routes are served by over 200 vehicles, mostly in central Toronto. All of the streetcar routes have at least one connection to the subway. As a result of the good coverage provided by the streetcars in the downtown area, there are very few standard buses that operate in central Toronto.
The bus network is also one of the largest in North America, with over 2000 buses serving over 150 routes (only Los Angeles and New York have larger systems). Almost every route has a connection to a subway station. The fleet is now entirely handicapped accessible and many buses have bike racks on the front. A network of night buses means that buses are in operation 24 hours a day, 7 days each week.
Outside of Toronto itself, bus service in the York Region is provided by York Region Transit (YRT). YRT also operates the Viva Rapid Transit system, a very successful bus rapid transit connecting the York Region to Toronto.
The Toronto Streetcar network is the largest streetcar network in North and South America in terms of track miles, fleet size, and ridership. The current system has 51 miles of track and a fleet of 248 vehicles. In downtown Toronto, the streetcars provide most of the TTC's service on the street surface.
York Region Transit (YRT) was founded in 2001 through the merger of five municipally managed transit agencies. Today, it is the operator of bus services in the York Region of Ontario. YRT operates 65 bus routes, including 5 "Viva Rapid Transit" routes. YRT services are provided by private operators under contract
