People on subway

Ontario Line

A new 15.6-km subway line in Toronto that will run from Exhibition Place, through downtown, all the way to the Ontario Science Centre.

Overview

The Ontario Line will be a 15.6-kilometre subway line that will make it faster and easier to travel within Toronto and beyond.

The line will bring 15 new stations to the city and will run from Exhibition Place, through the heart of downtown, all the way to the Ontario Science Centre. It will give people more time back in their days, with a trip from one end to the other taking less than 30 minutes compared to the 70 minutes it takes on transit today. There will also be significant relief from crowding throughout the existing transit network thanks to connections to more than 40 other travel options along the way, including the TTC’s Line 1 and Line 2, three GO Transit rail lines, and the Eglinton Crosstown LRT.

Construction is now underway.
