More Union Station construction projects get under way

In January 2010, GO Transit officially launched its multi-year, multi-million dollar project to rehabilitate Union Station for train passengers.

The GO project includes:

  • renovating the train-shed roof;
  • building a new south platform;
  • improving passenger access to the platforms;
  • upgrading signals;
  • improving the tracks;
  • replacing switches; and
  • building a new yard to store trains in the middle of the day.

(Some of this work actually started as early as 2006.)

Meanwhile, the TTC and City of Toronto are starting work on separate projects in and around the station.


On Wednesday, February 23, TTC contractors started working on the project to build a second platform for subway passengers at Union subway Station. For the first phase of this project, they’ll remove the centre median on Front Street West between Yonge and York Streets and on Bay Street from Front West to the railway bridge.

The TTC expects work on Front Street to last five weeks, while work on Bay Street would likely last one week. At least one lane of traffic in each direction will be open at all times. The work proceeds Mondays to Saturdays between 7 a.m. and 11 p.m. and Sundays and holidays between 9 a.m. and 11 p.m. Two lanes of traffic in each direction will be open at all other times of the week.

By adding a second subway platform and expanding the concourse to include a single TTC fare-paid area and pedestrian by-pass routes, the TTC hopes to reduce overcrowding and improve passenger circulation through the station.

How the work affects transit service: Starting Monday, February 14, the TTC revised service along the 6 Bay route to accommodate the construction,


While GO works on renewing the train shed and rail components of the station, the City has its own project to renovate and upgrade the building, which it owns.

The City plans to:

  • triple the size of the GO Transit concourse to accommodate more than twice the current number of GO passengers at Union Station by 2030;
  • restore heritage aspects of the main building;
  • refurbish the west wing for Metrolinx’s head office;
  • build a new northwest connection to the underground PATH network;
  • enhancing pedestrian concourses to improve traffic flow; and
  • creating a new lower retail level below the station.

Tomorrow, Wednesday, March 16, City contractors start construction in the York Street Concourse.

How the work affects transit service: The construction blocks the stairwells from platforms 10 and 11 that lead to the concourse. GO Transit passengers can continue to use all other stairwells from platforms 10-11 to York and Bay Streets.
