The Toronto subway is a rapid transit system serving Toronto and the neighbouring city of Vaughan in Ontario, Canada, operated by the Toronto Transit Commission (TTC). It is a multimodal rail network consisting of three heavy-capacity rail lines operating predominantly underground, and one elevated medium-capacity rail line. As of December 2022, three new lines are under construction: two light rail lines and one light metro line.
In 1954, the TTC opened Canada's first underground rail line, then known as the "Yonge subway", under Yonge Street between Union Station and Eglinton Avenue with 12 stations. As of 2018, the network encompasses 75 stations and 76.9 kilometres (47.8 mi) of route. In 2022, the system had a ridership of 235,740,000, or about 880,200 per weekday as of the first quarter of 2023, making it the  second busiest rapid transit system in Canada in terms of ridership.
