Impact on local residents
Controlled microblasting excavation work
Microblasting excavation work will begin on September 15, 2025, at the site. For more information, see the Microblasting section further down this page.
Excavation work - Starting in mid-May and ongoing for 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 entrances and exits 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 at the corner of Pie-IX and Jean-Talon this fall?
A good neighbor committee will be set up in the coming weeks as a space for dialogue between the STM and the local community. We’re currently looking for people who live in the area to join the committee and represent local residents at a few meetings per year.
For now, discussions will focus on the Pie-IX station worksite, but the Provencher auxiliary building worksite will also be addressed when it’s set up in 2025.
The committee’s purpose is to:
- Provide information and outline the different phases of the project.
- Start a dialogue between residents and project representatives that will continue throughout the work.
- Discuss how the impact of the work will be managed so that resident members can share this information with their local community.
- Understand the concerns residents have about the work and find solutions together.
- Allow local residents to make suggestions on specific topics chosen by the project office.

Microblasting
Controlled microblasting excavation at the future Provencher auxiliary building will begin on September 15 and continue until the end of 2025. Occasional vibrations may be felt by residents near the worksite.
An independent consulting firm carried out surveys (especially photographs) on all buildings around the work site. These inspections document the condition of the buildings before and after construction. In the unlikely event that any damage is reported, an expert opinion will help to determine whether the damage is the result of the vibrations produced by the work site. Property owners affected by this measure have been contacted before the start of microblasting work.
Carbon monoxide detectors were distributed to properties within a 100-meter radius of the worksite.
- The site has already been partitioned off, and the microblasting will take place within the construction zone.
- Safety instructions will be posted around the site.
- Blasting mats will be installed over the rock to contain the micro-blasts.
- No explosives will be stored on site.
- We’ve hired a specialized firm to monitor the vibrations and ensure compliance with the City of Montréal’s standards.
- 12 whistle or siren sounds
- 30-second wait
- Microblast
- 1 long whistle or siren sound
- End of microblasting
The controlled microblasting excavation work will begin on September 15 and continue until the end of 2025. There will be an average of 1 to 2 microblasts per week.
For safety reasons, during each microblasting operation, a restricted area around the site will be temporarily closed to traffic, for a period of about 10 minutes. Employees will be present to coordinate this maneuver.
