Toronto Transit Commission
public transport agency

The Toronto Transit Commission (TTC) is the primary public transit agency in Toronto, Ontario, Canada, operating the majority of the city's bus and rail services. It is the oldest and largest of the urban transit service providers in Canada and has numerous connections to systems serving its surrounding municipalities.
Established as the Toronto Transportation Commission in 1921, the TTC operates 5 rapid transit lines, 74 subway stations, 43 light rail transit stops, approximately 167 bus routes, and 11 streetcar lines. The TTC is the most heavily used urban transit system in Canada; in 2025, the system had a total of 800,212,000 boardings.
History
Public transit in Toronto started in 1849 with a privately operated transit service. In later years, the city operated some routes, but in 1921, assumed control over all routes and formed the Toronto Transportation Commission to operate them. During this period, streetcars provided the bulk of the service. In 1954, the TTC adopted its present name, opened the first subway line from Union to Eglinton, and greatly expanded its service area to cover the newly formed municipality of Metropolitan Toronto (which eventually amalgamated into the present City of Toronto). The system has evolved to feature a wide network of surface routes, with the subway lines as the backbone. On February 17, 2008, the TTC made many service improvements, reversing more than a decade of service reductions and only minor improvements.
