Led by Metrolinx, the Hurontario-Main Light Rail Transit line will have 26 stops, including three in downtown Mississauga and two in Brampton. The line will run from the Port Credit GO station north to the Brampton GO station.
The line will also connect to many of the region's existing transit lines including GO Transit's Kitchener, Milton and Lakeshore West rail lines, Brampton Züm, and the Mississauga Transitway.
Brampton Mayor Linda Jeffrey said the new line will "transform Peel Region" while Mississauga Mayor Bonnie Crombie called the new line a "game changer."
Construction on the line is expected to begin in 2018 and completed by 2022.
