Toronto subway owned by Toronto Transit Commission
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.Line 6 Finch West
Line 6 Finch West, also known as the "Finch West LRT", is an under-construction line being built by Mosaic Transit Group along Finch Avenue. It is to be operated by the Toronto Transit Commission and was also part of the Transit City proposal announced on March 16, 2007. The 11-kilometre (6.8 mi), 18-stop line is to extend from Finch West station on Line 1 Yonge–University to the north campus of Humber College. The line is forecast to carry about 14.6 million rides a year or 40,000 a day by 2031. It is scheduled for completion in 2023, with an estimated cost of $1.2 billion. Construction on this line began in 2019.
