The Ontario Line is a rapid transit line under construction in Toronto, Ontario, Canada. Its northern terminus will be at Eglinton Avenue and Don Mills Road, at Don Valley station, where it will connect with Line 5 Eglinton. Its southern terminus will be at the existing Exhibition GO Station on the Lakeshore West line. The Ontario Line was announced by the Government of Ontario on April 10, 2019. As of August 2024, the estimated cost for the 15.6-kilometre (9.7 mi) line is CA$27 billion with an estimated completion in 2031. Originally, the cost was estimated at $10.9 billion with completion by 2027. A groundbreaking ceremony for the project took place on March 27, 2022. Upon opening, the plan is for the line to be numbered as "Line 3". This number was used by Line 3 Scarborough until its closure in July 2023.
