To start off the month of February, commuters can expect a weekend full of subway closures. 

This time around, there will be no subway service on Line 1 between Spadina and Union stations on February 2 and no subway service on Line 1 between St Clair West and Union stations on February 3. This is due to installation of the new Automatic Train Control (ATC) signalling system.

If that's not rough enough, subway service on Line 1 between Union and King stations will end early on February 3 at 10 p.m.

Line 1: Weekend closure update. To lessen the impact to customers, St Clair West & Dupont stations will remain open on Saturday. The closure for ATC signal upgrades will only be from Spadina – Union. The Sunday closure will remain unchanged. See https://t.co/EGLgVxpzbi for more. pic.twitter.com/5aZSqUJhab

As always, shuttle buses will operate between these stations for the duration of the closure.

Regular scheduled subway service will resume on Monday morning. The next scheduled closure will halt weekend subway service on Line 1 between St. Clair and Lawrence stations on February 9 and 10 to accommodate work by Metrolinx on the Eglinton Crosstown Light Rail Transit project.
