The Toronto Transit Commission (TTC) is shutting down eight consecutive subway stops this weekend, meaning your commute might be a bit slower than usual.

On Saturday, April 1, and Sunday, April 2, there will be no subway service on Line 1 between Bloor-Yonge and York Mills Station.

You can thank the work being done on the Automatic Train Control (ATC) signal system for this closure, a necessary system that allows the TTC to safely run more trains closer together.

Shuttle buses will transport commuters through these eight stops until regular subway service resumes on Monday, April 3, at 6 a.m.

Summerhill Station will be closed; however, all other stations will remain open for customers to load their PRESTO cards and connect to surface routes.

The closure for ATC work comes just a few months after the system's completion, ending a construction schedule responsible for years of rolling weekend subway outages.
