No subway service, St Clair West to Union:
April 21, 22

TTC crews continue installing the automatic train control signal system (ATC) on its Line 1 Yonge - University subway this weekend. To allow crews to complete this work, the TTC is closing the University branch of the line between St Clair West and Union stations Saturday, April 21 and Sunday, April 22.

Line 1 trains operate only between Finch and Union stations and between Vaughan Metropolitan Centre and St Clair West stations.


Express shuttle buses replace subway service — but only between St Clair West and Spadina stations. The buses operate on streets near or parallel to the subway line, stopping only on Spadina Road at Dupont Street, near Dupont Station. Buses don’t operate south of Bloor Street.

Wheel-Trans vehicles are available during the closure for passengers who use wheelchairs, scooters or other mobility devices or who require more accessible service. Ask any TTC employee for Wheel-Trans service.

As alternatives to the closed part of the line, the TTC encourages passengers to consider boarding:

  • trains operating along Line 2 Bloor-Danforth;
  • trains operating along the Yonge branch of Line 1 Yonge - University;
  • north-south buses operating along the 6 Bay route; and
  • east-west streetcars operating along the 501 Queen, 504 King, 505 Dundas, 506 Carlton,512 St Clair and 514 Cherry routes.

St Clair West, Spadina, St George and Union stations are open for passengers to buy fares or connect to buses and streetcars. Dupont, Museum, Queen’s Park, St Patrick, Osgoode and St Andrew stations are closed.

According to a TTC news release, “When ATC is fully implemented in 2020, it will provide a more modern and reliable signal system that will allow for an increase in the number of trains operating on Line 1. While the TTC does most subway maintenance at the conclusion of service each night, it continues to require weekend closures to complete ATC and state-of-good-repair work. One weekend of work during a closure is equivalent to about five weeks of nightly work.”

This is the last time this year that the TTC plans to close this section of the line. It previously closed this part of the subway system Saturday February 3 and Sunday, February 4 and Saturday, March 10 and Sunday, March 11.

The TTC has not announced the path for the shuttle buses during this closure.

eastward along St. Clair Avenue West;
southward along Spadina Road;
westward along Austin Terrace;
southward along Walmer Road and Kendal Avenue;
eastward along Macpherson Avenue;
southward along Spadina Road; and then
eastward into Spadina Station bus terminal,
ending their trips.

Northbound buses start their trips in Spadina Station bus terminal, then proceed:

northward along Spadina Road;
westward along Davenport Road;
northward along Walmer Road;
eastward along Austin Terrace;
northward along Spadina Road;
westward along St. Clair Avenue West; and then
northward into St. Clair West terminal,
ending their trips.
