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.

The TTC thanks you for your patience and understanding during our subway closures.
