Union Station

Union Station Enhancement Project

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. 

We’re upgrading the 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.

With these enhancements, 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.

Multiple projects taking place in and around Union Station – including track enhancements and signalling upgrades – must be completed prior to the implementation of the major service increases planned as part of GO Expansion

Once these upgrades are complete, we’ll have the capacity to run up to 80 trains per hour through Union Station during peak periods – four times the current level.

The Union Station Enhancement Project is currently in construction. For more information on project phases, please check out our project lifecycle page.

Project overview

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

  • Improved GO train platforms with canopies
  • More stairs and elevators to access platforms and reduce crowding
  • A new concourse between Bay and York streets that will provide connections into the York, VIA, and Bay concourses, Union Square and Scotiabank Arena
