Union Station Revitalization

We're Transforming Union Station!

Map showing completed and upcoming work at 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.

Closure of walkway on the east side of Bay Street

The walkway on the east side of Bay Street (Bay East Teamway) is closed for construction until later in 2021. This includes the closure of all stairs leading to train platforms in the walkway. However, the entrance to the new Union Station Bus Terminal from Bay Street will be open beginning December 5, 2020.

If you use the walkway on the east side of Bay Street to access train platforms, here are your options during the closure.

When boarding your train at Union Station:

  • You can access platforms 4 to 13 and platforms 24 to 27 from the walkway on the west side of Bay Street (Bay West Teamway).
  • Plan your new route in advance and give yourself extra time.

When exiting your train at Union Station:

  • The exits at the east end of the platform will be closed for construction.
  • Please follow signs to safely exit the platform and don’t enter construction areas.
  • Remember to stay behind the yellow line and do not cross train tracks.

Your safety is our top priority. We’re committed to closely monitoring the number of customers on our vehicles and in our stations and we will re-open the walkway on the east side of Bay Street early if needed.

We’re renovating the walkway for you and replacing the ceiling, flooring, windows and doors and improving digital signs.

This walkway will connect the new Union Station Bus Terminal with a future commercial tower at 141 Bay Street.

Other Works

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

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

Once the Bay Concourse is complete, both Union Station concourses combined will be triple their original size and will 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

When the City wraps up that work later next year, they’ll hand the area over to us to customize. That work will take several months to complete.

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

Starting this year, we’re making improvements at the platform level to give you more efficient, frequent and comfortable GO service. These include:

  • Building a new platform to reduce overcrowding during peak hours and add more train capacity to the station
  • Widening existing platforms
  • Constructing a roof structure over the new platform to protect you and GO equipment from the weather
  • Constructing a pedestrian concourse area below the new platform to improve circulation through the station
  • Installing an improved emergency power system to keep our services running during a power outage

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.

Guided by the Regional Transportation plan, Metrolinx is expanding our network to ensure connections across the Greater Golden Horseshoe. We’re building to increase GO service to four times the number of trains across the network per day. So, when it comes to building transit, it’s time to get moving. That’s why Metrolinx is delivering the largest transit infrastructure program in Canadian history to keep the Greater Golden Horseshoe moving today and tomorrow. Learn more.
