Line 6 Finch West

Line 6 Finch West, also known as Finch West LRT, is a light rail transit line in Toronto, Ontario, Canada. Operated by the Toronto Transit Commission (TTC) as part of the Toronto subway, the 10.3-kilometre (6.4 mi), 18-stop line extends from Finch West station on Line 1 Yonge–University at Keele Street to Humber College station at the North Campus of Humber Polytechnic in the district of Etobicoke. The line operates in a dedicated at-grade right-of-way segregated from street traffic, much of it within the median of Finch Avenue West. It uses standard gauge rather than the broad Toronto gauge used by the three older heavy rail subway lines.

The line is forecast to carry about 14.6 million rides a year or 40,000 a day by 2031. It replaced the 36C Finch West bus route (west from Finch West station) branch, which was one of the three busiest bus routes in Toronto. In the 2010s, the route had approximately 42,600 passengers per weekday, with forecast demand in 2031 that would have resulted in 32 to 39 articulated buses or 45 to 55 standard buses being required to serve the route.

The provincial agency Metrolinx announced in October 2025 that the line had achieved substantial completion, and the TTC officially opened the line on December 7, 2025.
