Toronto commuters will have to plan around a major service disruption this weekend, when the TTC shuts down eight stations on the Line 1 Yonge-University route on Saturday, November 4 and Sunday, November 5.

An almost 10.5-kilometre stretch of Line 1 between St Clair and Finch stations will be closed for the duration of the weekend to accommodate track work.

The closure will also give crews a window to accelerate ongoing construction work on the Lawrence Station Easier Access plan, which is adding two new elevators to the station to improve accessibility.

Service on the northern portion of Line 1's Yonge branch (roughly one-quarter of the entire route length) will be replaced with shuttle buses throughout the duration of the closure.

Riders trying to navigate the extensive closure can also transfer via surface routes and connect with subway stations on the unaffected University-Spadina-York branch of Line 1.

Regular service on Line 1 will resume on Monday, November 6, by 6 a.m.

Throughout the closure, Lawrence Station and North York Centre Station will be inaccessible to commuters. Other stations affected by the closure will still be open for PRESTO card purchases and reloads, as well as connections to surface routes.

Planned outages have become increasingly common this fall, and the TTC has regularly cut service through a mix of late openings, early closures, as well as single-day and full-weekend service interruptions as the transit agency advances several repair and improvement projects.
