Toronto subway

The Toronto subway is a rapid transit system serving Toronto and the neighbouring city of Vaughan in Ontario, Canada. It is operated by the Toronto Transit Commission (TTC), an agency of the City of Toronto. The system is a rail network consisting of five lines: Line 1 Yonge–University, Line 2 Bloor–Danforth, Line 4 Sheppard, Line 5 Eglinton, and Line 6 Finch West. In 1954, the TTC opened Canada's first subway line, then known as the "Yonge subway" and now part of Line 1, under Yonge Street between Union Station and Eglinton Avenue with 12 stations. As of 2026, the network encompasses 109 stations and 99.4 kilometres (61.8 mi) of route. In 2025, the system had a ridership of 331,789,000, or about 1,087,000 per weekday as of the second quarter of 2026, making it the busiest rapid transit system in Canada in terms of daily ridership. As of May 2026, there are 26 stations under construction as part of the Ontario Line and three extensions to existing lines.
