No subway service, St Clair West to Union,
March 30, 31


This Saturday, March 30 and Sunday, March 31, the TTC is closing the Line 1 Yonge - University subway between St Clair West and Union stations, as crews continue installing the automated train-control (ATC) signal system. Line 1 subway trains operate only between Vaughan Metropolitan and Spadina stations and between Finch and Union stations this weekend.

Shuttle buses operate, stopping on the street near each station along the closed section of the line. Most stations along this part of the line remain open to passengers so you can buy fares or access connecting buses, streetcars and subway trains. However, Museum and Dupont stations are closed.

The TTC says it’s also adding extra streetcars along the 510 Spadina and 512 St Clair routes to help passengers get around while part of the subway system is closed.

Wheel-Trans is available at each station along the closed section of the line throughout the weekend. You can speak with a TTC staff member to ask about the accessible service and its frequency.

According to a TTC news release, “When ATC is fully installed on Line 1, it will provide a more modern and reliable signal system that will help the TTC improve capacity by allowing for increased trips on the line. While the TTC does most subway maintenance at the conclusion of service each night, it continues to require weekend closures to complete critical infrastructure and ATC upgrades… [and] work on the Eglinton Crosstown” light rail transit project.

Full subway service along Line 1 resumes by 6 a.m. Monday, April 1.

The TTC has already closed this section of Line 1 several times earlier this year:
