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). As of September 2023, the subway system is a rail network consisting of three heavy-capacity rail lines operating predominantly underground. 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 2023, the network encompasses 70 stations and 70.1 kilometres (43.6 mi) of route.
