Renovations at Saint-Michel métro station

Renovation work will be carried out at Saint-Michel station starting on Monday, March 11. The work will involve modernizing and refurbishing certain parts of the station and is not related to the Blue line extension. These types of asset maintenance projects are essential to the smooth operation and long‑term viability of our network.

If you have any questions, please visit the project web page.

Construction on the new Saint-Michel power station for the Blue line extension will begin in late 2025.

Next step

Get involved

A power station is an operational infrastructure that houses equipment needed to supply power to the métro network. There are currently 7 power stations located across the STM métro network. The Blue line extension to the east requires that we update our electrical equipment to meet new energy demands.

We will also use the Saint-Michel power station building to house offices that will be used by métro operations employees.

No, this type of infrastructure does not generally generate noise or fumes. However, it houses diesel generators, which are very rarely operated. In addition, there will be a few STM service vehicles parked behind the building.

Keeping the existing building, located at 7355 Saint-Michel Boulevard, was not feasible, as it does not meet all our specific requirements. Métro operational infrastructures must comply with a variety of internationally recognized standards.It is also important to know that the new equipment will be particularly massive and voluminous, which requires custom construction.

Yes, that is our intention. Renovation work are planned for the coming years inside the station, but it will remain functional despite certain constraints.
