Union Station

Union Station Enhancement Project

We’re upgrading Union Station to support the creation of a network that has the capacity to deliver two-way, all-day service every 15 minutes or better along core segments of the GO rail network. 

  • New reconfigured platforms and more convenient access to and from the concourse levels below, as well as increased service levels across the network as trains move through the station faster and more efficiently. 
  • Improvements to Union Station are being completed in phases as part of GO Expansion and is anticipated to allow for approximately 80 trains per hour – quadruple the current level – to move through the station.  
  • The multiple projects taking place in and around Union Station must be completed prior to the implementation of the major GO service increases planned as part of GO Expansion.  
  • GO Expansion will offer more service with faster trains, more stations, and seamless connections to a regional rapid transit network.   

Union Station is the gateway to the region and is undergoing much needed modernization while preserving heritage features to meet transit needs now, and in the future. 

  • A new south passenger concourse spanning from Bay to York Streets will have convenient open concept connections into the York, VIA, and Bay Concourses, Union Square and Scotiabank Arena. 
  • New improved platforms and more convenient access to and from the concourse levels below will allow more room for customers to efficiently move through the station.

Project overview


Here are some of the improvements we’re making today to allow for more trips, more often across the network:

  • Improved GO train platforms with canopies
  • More stairs and elevators to access platforms
  • A continuous concourse between Bay and York streets

The final track and platform configurations for Union Station are being refined through a collaborative effort between OnTrack Alliance (Union Station Enhancement Project) and ONxpress Transportation Partners (OnCorridor Works) teams to ensure future service levels at Union Station planned as part of the GO Expansion Program can be achieved. As part of future phases of work, ONxpress will redesign and widen Union Station’s platforms, and add more stairs and elevators to improve the passenger experience at this critical transit hub. 

With this expansion, GO will better serve the thousands of passengers who move through Union Station each day and will make the station less crowded, more convenient and comfortable for customers.
