Maintaining subway infrastructure in a state-of-good-repair is critical to ensuring a safe, reliable transit system. While the TTC does much of its maintenance work on the subway at the conclusion of service each night, it will continue to require weekend closures to complete improvements to infrastructure and signals, such as automatic train control. One weekend of work during a subway closure equals about five weeks of nightly work.

Please note that 24 of the weekend closures scheduled for 2018 were initiated by Metrolinx to accommodate Eglinton Crosstown LRT construction at Yonge Street and Eglinton Avenue. The TTC will take advantage of those closures for maintenance and upgrades in the affected areas.

The TTC appreciates your patience and understanding.
