No subway service, St Clair West to Union:
March 10, 11



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, March 10 and Sunday, March 11.

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 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.”

To keep shuttle buses and all traffic flowing as smoothly as possible, the City of Toronto is temporarily prohibiting parking on Spadina Road between Dupont Street and Bloor Street West from 7 a.m. until 9 p.m. Saturday and from 9 a.m. until 9 p.m. Sunday.

This is the second time this year that the TTC has closed this section of the line. It previously closed this part of the subway system Saturday February 3 and Sunday, February 4.

It expects to close it once more for ATC work in 2018 — the next time is Saturday, April 21 and Sunday,April 22.
