Track repairs, signal testing and HVAC installments. TTC Subway service is being interrupted for all sorts of reasons this weekend. The good news is, most of the work is being confined to off-hours so, unless you rely on Line 3, this weekend's closures shouldn't have too much of an impact on you.

How To Navigate The Service Disruptions

Shuttle buses will operate along the normal subway route. Buses will stop at all the regular subway station stops, just outside the typical zone. Wheel-Trans will also be available to TTC riders requiring accessible service.

Since Wilson station is not yet an accessible station, customers travelling north on Line 1 should exit at Lawrence West station and see a TTC employee for Wheel-Trans assistance.

Normal service will resume on Monday morning.
