Proposed frequencies

In 2022, Metrolinx estimated that with GO Expansion, GO Transit would have the ability to run up to three times more trains than the 3,500 trains per week it ran in 2019. The busiest routes could operate between 8 and 18 trains per hour. Trains at GO stations such as Exhibition, Bloor and East Harbour could have a frequency of every 3 minutes and a 5-minute frequency at stations such as Burlington and Pickering. Evening and weekend service could be as frequent as every 6 to 15 minutes. The following more modest frequencies were projected in 2015.

Two-way all-day service

GO Expansion will see many sections of GO train lines receiving two-way all-day service. Sections proposed to get two-way all-day 15-minute or better are: * Lakeshore West line between Burlington and Union Station * Lakeshore East line between Oshawa and Union Station * Kitchener line between Bramalea and Union Station * Barrie line between

SmartTrack

SmartTrack started out as a proposed Regional Express Rail surface service to run mostly within the City of Toronto. It was proposed by John Tory during his successful mayoral campaign in 2014. The SmartTrack proposal depends on electrification of the Stouffville and Kitchener corridors where SmartTrack service would run. As a part of the agreement reached between Metrolinx and the City of Toronto, five stations will be built within the City of Toronto and are expected to open by 2026; these are , , (Liberty Village), East Harbour, and .
