Starting June 7

The following platform changes will be made as of Wednesday, June 7, 2017:

  • Milton Line: All afternoon trains leaving Union Station will depart from platforms 7 and 8
  • Lakeshore West Line: most afternoon trains departing Union Station, except the 17:15 express train, will board on platforms 9 and 10. The 17:15 Lakeshore West express train will continue to depart on platforms 11 and 12

Always check the departures boards before heading up to the platform – platform changes can happen at any time.

All of the platform changes are to facilitate the next phase of the Union Station Revitalization Project, which involves refurbishing the steel train shed structure and installing a new roof on top of it. To do this work, we’ll be closing platforms 4 to 6 and the tracks that serve them, meaning we have to find different locations for our trains to line up in the station. We will be re-opening platforms 7 to 10 the same day.

Platform Map


The best commute is a safe one. We anticipate crowding on our platforms so please spread along the platform, be aware of your surroundings and leave yourself with extra travel time. And always remember to stand behind that yellow line, as it puts you at a safe distance from oncoming trains. For your safety, please do not block stairwells or doorways, and do not stop at the bottom or top of escalators. Most importantly, you should never cross the tracks. Thank you for your patience as we work to improve Union Station.

Union Station Revitalization


The revitalized structure and new roof will result in a safer, more comfortable experience for our customers by protecting them and our infrastructure from the elements. The train shed space that extends beyond the recently completed glass atrium totals 30,000 square metres, all of which is being renovated and restored. The nearly 90-year-old structure is designated as a National Historic Site of Canada.

Construction and related platform and schedule adjustments will continue until the project is complete.

Our commitment

More than 200,000 GO Train customers travel to and from Union Station on a given weekday, and we know it can be difficult to adjust to these changes. Union Station is our country’s busiest transportation hub, and maintaining and increasing service for our customers as we carry out this work is a big undertaking. We are committed to continually looking at ways to improve our service as we complete this project, and we encourage customers to share their feedback so we can make improvements wherever possible.

Continuing improvements

Revitalizing Union Station is critical in ensuring our country’s busiest transportation hub can continue to meet our needs. The construction of the train shed roof builds upon the completion of the new glass atrium within the train shed in 2015, the opening of the new GO York Concourse in 2015, and the ongoing renovation of the Bay Concourse, which is well underway and set to open in 2018.
