SmartTrack is all-day, two-way, frequent Regional Express Rail (RER) service across the city.

SmartTrack uses underutilized, existing GO rail lines to connect all 4 corners of the city in just 7 years.

SmartTrack will run from Unionville (Markham) in the east to Union Station to Mount Dennis, where it will link with the Crosstown LRT which will in turn run to the Airport Corporate Centre (Mississauga) in the west. More than 90 per cent of its length will be on existing GO tracks, which will be retrofitted for use by electric multiple unit vehicles (EMUs)..

SmartTrack will bring much-needed transit and congestion relief to the whole city. Currently, hundreds of thousands of commuters ride buses into the northern stations of the Yonge-University-Spadina line, leading to serious crowding on trains, and inevitable delays. When these commuters head south to Bloor/Yonge and St. George stations, it results in a critical overload to the system.

A University of Toronto study commissioned by the city estimated that, with five minute service and the same fare as the TTC, SmartTrack would attract 315,000 riders in 2031—more than the entire GO network. With 10 minute service, ridership would be 154,000 and with 15-minute service: 77,000.

SmartTrack will draw commuters to alternate entry points along the east-west transit corridor, which will dramatically reduce passenger use on the Yonge-University-Spadina line.

Furthermore, SmartTrack will reduce car congestion in and around the areas it services

It will provide city-wide relief from traffic and transit congestion.
SmartTrack will also bring rapid transit to corners of the city that have never had it, including northwest Etobicoke and northeast Scarborough. Current transportation and transit infrastructure is not allowing the GTHA to reach its full economic potential. SmartTrack actually responds to the current economic and geographic reality of the GTHA by connecting major employment centres in downtown with the suburbs. It will enable transit users to connect with employers and jobs in other parts of the city, not just downtown. Linking employers to employees will result in productivity gains, enhanced labour market allocation and commercial real estate development.



Approximately 90% of SmartTrack would run along corridors that are already in public hands, so it will not displace any existing roadways.
