Impact on customer trips

There are no additional impact on customer trips apart from modifications to the bus commute already in place for the duration of the project.

Impact on local residents

In spring 2025, construction of a new auxiliary building began at the intersection of Jean-Talon and Provencher streets. In order to complete the various stages of the project, the work will be spread out over several years.

 
  • The sidewalk on the west side of Provencher Boulevard as well as the north sidewalk of Jean-Talon Street facing the worksite remain accessible.
  • Flaggers are present at the site entrance and exit to ensure pedestrian safety.
  • Be vigilant and make sure you cross at the traffic signals, use pedestrian crossings and comply with all instructions issued by traffic controllers.

Join your local good neighbour committee!

Do you live near the future Vertières station or Provencher auxiliary building and want to have your say in how the Blueline project worksites will fit into your neighbourhood?

A good neighbor committee has been set up as a space for dialogue between the Blue line extension project team and the local community. We’re currently looking for people who live in the area to complete the committee and represent local residents at a few meetings per year.

Write to us to apply or to find out more.


Microblasting (completed)

Controlled microblasting excavation was used at the future Provencher auxiliary site between fall 2025 and summer 2026. Now that the vertical excavation at the construction site has been completed, controlled micro-blasting will no longer be required for the remaining phases of the work.
