Part of the Bloor subway will be closed this weekend for track work.
Service between Keele and Kipling stations was shut down at midnight on Friday so crews could replace the crossover track at Jane.
The TTC is running shuttle buses stopping in Keele, Islington and Kipling stations and outside High Park, Runnymede, Jane, Old Mill and Royal York.
A Wheel-Trans vehicle will be available at Dundas West.
Normal subway service will resume on Monday at 6 a.m.
