What we are doing and why

The TTC will be conducting roof repairs at the main entrance building of Broadview substation. The main station entrance and TTC service will not be impacted by these work activities.

What to expect

Starting the week of June 14, work crews will create a safe work zone and start installing protective scaffolding around the entrance of the substation. Work is scheduled for completion by the end of October.

Once safe work is established, work activities will include the removal and installation of new roof flashings along the roof wall, removal of the old roof material and application of new roof material.

Materials deliveries from TTC’s roof supplier will be conducted between 5 a.m. and 7 a.m. multiple times during the course of the project. Some supplies will be stored on the roof.


The traditional method of liquid asphalt application (asphalt kettle) is not being used. The roofing system used is a 3-ply membrane applied with heat and produces less odour.

Dust and debris disposal

Dust will be controlled as much as possible. A fenced off area will be erected around material storage and disposal bins.

Work hours

Work will typically take place during regular daytime hours of 7 a.m. to 4 p.m., and may extend to 8 p.m. if needed. Safety sensitive activities and delivery of materials/supplies will occur outside of these hours.
