Union Station Enhancement Project

There are multiple projects underway at Union Station - all working toward the same goal - preparing the Union Station Rail Corridor for GO Expansion service levels. The Union Station Enhancement Project (USEP) is being completed in phases to deliver the required infrastructure needed to enable two-way, all-day service every 15 minutes or better along core segments of the GO rail network. The USEP includes the design and construction of transit infrastructure and upgrades at the southernmost part of Union Station.

Project overview


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

  • Two new wider GO train platforms with canopies, which will increase safety and capacity to serve more customers
  • New stairs and elevators
  • A new south passenger concourse spanning from Bay to York Streets, with convenient open concept connections into existing Bay, VIA, and York concourses, Union Square and Scotiabank Arena
  • Creation of two new south tracks


  • 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.
  • A more modernized and convenient open concept south passenger concourse will provide smoother, easier customer connections.
