Union Station Improvements

We're Transforming Union Station!

Tripling the size of Canada’s busiest transportation hub is an enormous and sometimes messy undertaking. We’re building the infrastructure for two-way, all day transit with 15-minute service or better within the most heavily travelled Metrolinx-owned rail corridors, twice the train trips during rush hour and four times the number of train trips outside of rush hour and on weekends. To support this massive expansion, we’re also adding signalling systems and larger platforms at the station, while improving the tracks and corridors feeding into it.

We’re making these improvements in a 100-year-old building while keeping transit services moving every single day. We’re putting you first by trying to minimize service disruptions during the renovation by tackling the construction in phases.

What's Changing

Bay Concourse is now open!

Reopening on July 27, the newly revitalized Bay Concourse will make it easier for you to spread out, giving you a safer and more comfortable transit experience at Union Station.

New access points will reduce crowding, making your commute even safer and more comfortable. Customers can now access the full length of the platform from the concourse level.

The reopening of Bay Concourse will help support physical distancing while you wait, by providing additional space, PRESTO and ticket vending machines, and more departure boards.

Updated signs have been installed throughout Union Station to help you get to the Bay Concourse, the Union Station Bus Terminal and to help you find accessible and barrier-free paths. Union Station Bus Terminal, which is located on Lakeshore West Boulevard, just east of Bay Street, now offers Megabus and Coach Canada bus service, along with GO bus service.

Improvements at the platform and concourse levels

We’re making improvements at the platform and concourse levels to give you more efficient, frequent and comfortable GO service. This means there are some changes to how you make your way around the station:

  • The doors between the south west side of the York Concourse and the stairs to platforms 24-27 are blocked for construction
  • To get to platforms 24-27 from the south west side of York Concourse, please follow directional signs in the area. 
    • From the south west side of York Concourse, please proceed to York Street, and head south (turn left) and after about 10 metres head east (turn left).
  • To get to the south side of York Concourse from platforms 24-27, please follow directional signs in the area. 
    • From the bottom of the stairs to platforms 24-27, please proceed to York Street, and head north (turn right) and after about 10 metres head east (turn right).
  • Sections of fencing will also be in parts of the walkways on the west side of York Street, and the walkway on the east side of Bay Street once it opens later this year. Please be careful around construction equipment and fencing.  

We need to close off portions of station pathways to make space to convert two heritage freight elevators and a heritage freight elevator enclosure into stairs. Once open, the three new stairways will make it easier and more efficient for you to get to and from platform 20/21.

Platform 20/21, currently used almost exclusively for VIA Rail service, will become a shared platform for VIA and GO Transit customers once construction is complete towards the end of this year.


To access the Union Station Bus Terminal (USBT):

The walkway on the east side of Bay Street has been renovated for easier access into the Union Station Bus Terminal (USBT).

  • The south end of the walkway on the east side of Bay Street connects directly to the Union Station Bus Terminal.
  • The entrance to the Union Station Bus Terminal from the south side of Bay Street is closed until later this summer due to construction in the area.
  • To access the Union Station Bus Terminal from Bay Street, you must enter from the north end of the walkway and walk through to get to the bus terminal.
  • Follow signs in the walkway to get to the bus terminal.
  • Elevators and escalator are available to get to L2 of the bus terminal.
  • You can still enter the Union Station Bus Terminal via the main entrance on Lake Shore Boulevard., just east of Bay Street.
  • Customers coming from Union Station can get to the bus terminal by heading to the Bay Concourse and accessing the Bay Street Bridge from the Scotiabank Arena exit. The Bay Street Bridge connects Scotiabank Arena and Union Station to the second floor of the Union Station Bus Terminal. This is an accessible path.

A future commercial tower at 141 Bay Street is still under construction. For information on the Union Station Bus Terminal, click here.


Other Works

The stairs from the walkway on the west side of Bay Street (Bay West Teamway) to Platform 3 are closed for construction on the façade of the Bay Street Bridge.

The City of Toronto is also working to revitalize the portions of Union Station it owns, including the Bay Concourse, Great Hall and VIA Concourse. Learn more on the City of Toronto's website.

How You Will Benefit

Now that the Bay Concourse is complete, both Union Station concourses combined are triple their original size and feature:

  • Better platform access, including the ability to access the full length of the platform from the concourse level.
  • Connections to a new retail level under the Bay Concourse, including the Fresh Market.
  • An improved, accessible connection to downtown Toronto's PATH system through the TTC Union Subway Station.
  • A new customer service counter, new PRESTO and ticket vending machines, more departure boards and new entrances to the street level.

To make trips even faster and easier while improving passenger accessibility, we also continue to build more stairs and elevators to train platforms, and repair existing ones.

What's Next

Once we’ve finished converting Platform 20/21 to a shared platform for VIA Rail and GO Transit services, improvements will include:

  • A new shared platform for VIA and GO Transit customers to board and exit trains.
  • Three new stairways to make it easier and more convenient for VIA and GO Transit customers to get to and from platforms 20/21.
  • New customer communications systems with trip information.
  • Several new PRESTO devices at the bottom of the escalators and stairs to platform 20/21.

The Union Station Enhancement Project (USEP) will begin once construction work for platform 20/21 is complete towards the end of this year. The project will be delivered in various packages of work and includes removing heritage steel, installing overhead lighting, a new south concourse, widening platforms, increasing vertical access, upgrades to passenger communications systems, train storage expansion in Wilson Yard and east track enhancements.

This work will require future boarding adjustments that may affect how you get to your train. We’ll keep you informed about any impacts to your journey. To get updates sent directly to your inbox or phone, sign up for On the GO alerts at onthegoalerts.gotransit.com.
