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.

The ramp between Union Station and 25 York Street is closed

The VIA-Telus connection (ramp) between Union Station and 25 York Street has closed permanently. 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. This connection has closed to build the new south concourse at Union Station.

Here's what you need to know:

Alternative routes once the VIA-Telus connection has closed

From Union Station to the south side:

  • Follow signs in the south hallway connecting all three concourses, to the newly built stairs and accessible ramp (located just in front of the entrance to Bay Concourse), which will bring you to the hallway leading to Scotiabank Arena (Bay-Scotiabank connection) as well as Union Station Bus Terminal, Bremner Boulevard, Union Plaza, and 25 York Street (Telus Harbour).

From the south side to Union Station:

  • Inside Scotiabank Arena follow signs to Union Station. Inside Scotiabank Arena follow signs to Union Station.
  • Make your way to the Scotiabank Arena hallway (Bay-Scotiabank connection), near Real Sports Apparel. You can then head straight to the Bay Concourse or to the newly built stairs and accessible ramp (near the Foodie Aisle), which will connect you to Bay, VIA and York Concourses, where you can access all train platforms.  

From Union Station to Gates and the Premium Entrance at Scotiabank Arena:

  • To get to Gate 1 at Scotiabank Arena, follow signs in the south hallway connecting all three concourses, to the newly built stairs and accessible ramp (located just in front of the entrance to Bay Concourse), which will bring you to the hallway leading to Gate 1.
  • To get to Gates 3, 4 and the Premium Entrance, follow signs to Bay Concourse and then to the Bay Street exit.
  • To get to Gates 5 and 6, follow signs to York Concourse and then to the York Street exit. 

Please plan ahead and give yourself extra time. Union Station is busier than normal due to multiple construction projects.

New south concourse construction may cause noise and vibrations

To increase the capacity of our south platforms, construction crews are demolishing platforms 24 to 27 to build two new, wider platforms and a new south concourse. While demolition is taking place, you may hear loud construction noise and experience frequent vibrations in the southernmost part of Union Station (Bay and York Concourses) during daytime hours.

Construction work includes:

  • Drilling the deep foundations to support the new south concourse floor.
  • Demolition of the track slab for existing platforms 24 to 27.

This work is taking place at track level and will progress from west (York Street) to the east side (Bay Street).

Construction resulting in noise and vibrations at the southernmost part of Union Station is expected to continue into spring 2023.

Once complete in the next few years two new wide platforms with canopies and two new tracks, will increase safety and capacity to serve more trains and get you where you need to go faster.

Bay Street West Teamway is partially closed

There is no direct access to train platforms from the Bay West Teamway (the indoor walkway on the west side of Bay Street). You can access platforms 3 to 13 from the Bay and York Concourses. Please plan ahead and give yourself extra time.

Accessing train platforms:

  • All platforms can be accessed from inside Union Station.
  • Platforms 4–13 and 20–21 can also be accessed from the Bay East Teamway (the indoor walkway on the east side of Bay Street).

From Union Station to Bay Street:

  • North: Use the Bay Street Promenade doors (near Sephora, just south of the TTC).
  • South: Use the doors at the south end of the Bay Concourse (just north of Scotiabank Arena).
  • The elevator in the Bay West Teamway is out of service. Alternate elevators are available in the Great Hall on the north side of the station or in the Scotiabank Arena on the south side of the station.

Pedestrians on Bay Street:

  • We’ve opened a previously closed portion of the Bay West Teamway and you can now use it to get from the south side (Scotiabank Arena area) to Front Street.
  • The sidewalk along Bay Street between Front Street and Lake Shore Boulevard West remains fully open.

The Bay West Teamway is expected to remain partially closed until spring 2023. 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.

We are building a temporary stairway

At Union Station we are building a temporary stairway to get you to the retail level below the VIA Concourse.

Here's what you need to know:

      • Two sets of doors to the VIA Concourse from the south hallway connecting York, Bay and VIA Concourses are unavailable during construction. We are building temporary stairs in this area to provide access to the retail level below in the near future. Please use the remaining sets of doors on either side to enter and exit the VIA Concourse.
      • There is a blocked off area for construction at the south entrance to the VIA Concourse.
      • Please be careful around construction and walk around fenced-off areas.

New temporary stairs are expected to be complete later this winter.
