Impact on local residents

In the coming months, two former gas station buildings will be removed to prepare the site for the excavation and construction of the future Langelier station.

What to expect

  • The dismantling will take place in the area outlined on the map above
  • The work will take place during the day, from Monday to Friday.
  • The building dismantling may cause noise, vibrations and dust.

Once the buildings are removed, the site will be fully cleaned and secured to prepare for the excavation.

To reduce the negative impact on residents, we will implement mitigation measures specific to the worksite and to each stage of the work.

Each stage will be carried out in accordance with all municipal by-laws.

The work involved relocating urban public utilities, giving us free rein to begin the massive excavation that will be needed to build the new métro station. The utilities that needed to be relocated included water pipes, sewers and underground conduits and cabling.

Before the preparatory work, the project team prepared informative video clips. Watch these clips to learn more about the project:
