Tripling the size of Canada’s busiest transportation hub is an enormous and sometimes messy undertaking. We’re putting you first by trying to minimize service disruptions during the renovation by tackling the construction in phases.

What’s Changing?

With the York Concourse complete and Bay Concourse construction well underway, there is still work to be done at Union Station. 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. New signalling systems and larger platforms are just some of the many improvements planned for Union Station to accommodate this massive GO expansion. Learn more about how Metrolinx is building connections across the Greater Golden Horseshoe.

Meanwhile, the City of Toronto is working to revitalize the portions of Union Station it owns, including the Great Hall, VIA Concourse and station concourses. For more information on those projects, please visit the City’s website.

We’ve been able to make all of these improvements in a 100-year-old building while keeping transit services moving every single day — which is no easy task. The multi-year project to improve your experience at Union Station will mean some future boarding adjustments and other changes as we make it easier to access your train and widen some platforms, create better connections to transit and local attractions and add more amenities, including a retail level and new food options.

Thank you for your patience as we continue to upgrade and improve Union Station.


Bay Concourse

Bay and York Concourses

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
  • 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

The City of Toronto is renovating the Bay Concourse for us and is planning on handing it over later this year. We’ll then take several months to customize the area – to add to your easy and convenient travel experience with us.

Bay Concourse
More Stairs and Elevators


To make trips even faster and easier while improving passenger accessibility, we continue to build more stairs and elevators to train platforms. Our improvements include:

  • Adding stairs and elevators between concourses and platforms, with elevator access to all GO platforms
  • Better access to the concourse and platforms from York East
  • Direct stair and elevator access to the Great Hall from the York Concourse
  • Escalators to the new retail level
  • Renovating existing stairs and elevators
More Stairs and Elevators
South Platform Grand Canopy


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 to make your commute safer and more comfortable
  • Installing new lighting, CCTV and PA systems
  • Constructing a roof structure over the new platform to protect you and GO equipment from the weather
  • Constructing an additional 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
Train Shed Roof

Platform Coverage

The train shed – the roof covering the platforms and tracks – is an essential part of Union Station's renewal. The east and west portions of the roof have been renovated and restored, and the centre portion has been replaced with a large glass atrium, providing sunlight to the platform level. Because the train shed is a designated heritage structure, we worked closely with Parks Canada on its renovation and construction.

New Train Signals

Signal Improvements

Modernizing our signal system will reduce signal disruptions, improve reliability and allow trains to move faster to get you where you need to go, easily and safely. This project will include work on the cable network, retaining walls, maintenance access roads that run parallel to the tracks, and the gas lines that supply heat for snow blowers on rail switches.
