Construction at Union Station

Construction Updates

Union Station Enhancement Project

We’re upgrading Union Station today to enable two-way, all-day service every 15 minutes or better along core segments of the GO rail network. Improvements to Union Station are being completed in phases, and will allow for 100 trains per hour, more than twice the current level to serve the station. Here’s what we have planned and impacts you could experience while at the station:

  • Construction is underway to complete a new south passenger concourse spanning from Bay to York Streets and offering convenient open concept connections into the York, VIA, and Bay Concourses, Union Square and Scotiabank Arena. The VIA-Telus connection (ramp) between Union Station and 25 York Street has closed permanently to make space for new south passenger concourse construction. Directional signs and onsite staff will guide you to the alternate routes to Union Station Bus Terminal, Scotiabank Arena and other destinations south of the station.
  • Platforms 24 and 25 and 26 and 27 were demolished, to make way for new, wider platforms with more room for passengers to efficiently move through or wait for trains. Platform 21 is open for GO Transit service with the addition of three new stairways to get you to the platform, located at the indoor walkway on the west side of York Street (York West Teamway), at the York Concourse near Uncle Tetsu’s Japanese Cheesecake, and at the indoor walkway on the east side of Bay Street (Bay East Teamway).

Construction for the new south passenger concourse, as well as new wider platforms is expected to be complete in the next few years. This is the Union Station of tomorrow. The heart of the GO network, connecting Toronto to every part of the Greater Golden Horseshoe.

New pedestrian bridge construction

There is no direct access to train platforms from the Bay West Teamway (the indoor walkway on the west side of Bay Street). All platforms can be accessed from inside Union Station. Please follow directional signs in the area. We need this space while important construction takes place for the new pedestrian bridge over Bay Street.

The Bay West Teamway is expected to remain partially closed until later this summer. Once complete, the new pedestrian bridge will connect Union Station to 141 Bay Street, the Bay East Teamway (the indoor walkway on the east side of Bay Street) and Union Station Bus Terminal.
