What we are doing and why?

This Spring, the TTC will be conducting roof rehabilitation at Dundas West Station as part of it’s state of good repair program. Some preliminary work may begin as early as March 27, 2019. The project is scheduled for completion by the end of Summer 2019.

During this project, the station will remain open and transit service will be maintained. Some routes may board at different locations.

At the start of the project, crews will create a safe work zone and install guard rails along the perimeter of the roof in preparation of roof work. Although the majority of the work will take place during the daytime, some activities will occur overnight for safety when there is less transit activity at the station.


The traditional method of liquid asphalt application (asphalt kettle) is not being used. The roofing system used is a membrane applied with heat, which should reduce the overall odour for our neighbours and customers using the station.

Dust and debris disposal

Crews will access and store material/equipment in two areas - at the north-east and south-west corners of the station platform/roadway. Material disposal bins will be placed near the north-east side of the station behind the elevator, surrounded by dust-tight and standard hoarding.

Efforts will be made to keep noise and dust to a minimum.

Work hours

Work will typically take place during regular daytime hours of 7 a.m. to 7 p.m., Monday to Friday, and Saturdays as required. Some overnight work including delivery of materials/supplies or working on the roofs edge may occur between 2:30 a.m. and 5 a.m.

TTC service

Subway, bus and streetcar service will be maintained at Dundas West Station. Some routes may board at different locations during this project. Signs will be installed at the station prior to any boarding location changes.

Thank you for your patience as we work to improve transit in Toronto.
