Starting 1:30 a.m. Saturday, September 24, the TTC is shutting down most of Line 1 Yonge - University subway as it tests the Automatic Train Control (ATC) system.

  • No service - After 1 a.m., the TTC is closing all service to stations on the downtown “U” — between St George and Bloor stations. Use Line 2 Bloor - Danforth to travel between the Yonge and University branches of Line 1.
  • No northbound service - After 1 a.m., it’s closing the northbound tracks between Bloor and Finch stations. Trains continue to operate southward between Finch and Bloor.
  • No northbound service — After 1 a.m., it’s also closing the northbound tracks between St George and Vaughan Metropolitan stations. Trains continue to operate southward between Vaughan and St George.

The TTC says that “Shuttle buses and alternate routes will be available. TTC staff will be on hand to direct [passengers] to shuttle boarding and offloading locations.”

All stations remain open so you can pay for fares or connect to TTC buses and streetcars and Line 2 Bloor - Danforth and Line 4 Sheppard subway trains — or Brampton Transit, GO Transit and York Region Transit buses.

Subway service on Line 1 resumes as usually Saturday, September 24 at about 6 a.m. — except the TTC is also closing all service between Finch and St Clair Stations as part of the ATC upgrade project.

The TTC says that “The existing signals, relays, wiring and cabling equipment, much of which is over 60 years old, need replacing as their failure significantly impacts service. Once Automatic Train Control is fully installed and operational, [passengers] will see improved frequency of subway service, less crowding and greater reliability of the signal system.”

According to a TTC news release, “While the TTC does most subway maintenance at the conclusion of service each night, it continues to require weekend and early weeknight closures to complete critical infrastructure and state of good repair work as well as ATC signal upgrades.”
