Latest update - March 2022

As announced last fall, upgrades to the Richelieu rectifier station have been taking place in the last few months. This work was carried out to ensure the durability of the rectifier for years to come and the reliability of the métro service.

We have completed most of the work at the rectifier station. Landscaping will be done when the weather permits, and it will mainly involve planting vegetation and installing a fence around the building. Landscaping activities will have limited impact on nearby residents and are expected to last about one week.

It should also be noted that the work at the Richelieu rectifier station is unrelated to the future work planned in 2022 at the Richelieu mechanical ventilation station, located on the same site.

Impacts on local residents

Part of the work will take place inside the Richelieu rectifier station. However, the noise generated on the worksite during the exterior work could carry to the nearby residences.

Trucks will need to be present on the worksite. This will not, however, impact local traffic or cause closures on De Richelieu Street.

The work will take place from Monday to Friday starting at 7 a.m., in accordance with municipal by-laws.

Work may occasionally be done on nights and weekends inside the rectifier station, but this will not create noise or inconvenience for nearby residents.

This work aims to ensure that the rectifier station remains operational for years to come and that the métro service is reliable.

Although the upgrade to the rectifier station will occur on the same site as the Richelieu mechanical ventilation station, the work being done is unrelated to the mechanical ventilation station. 

We care about the quality of life of residents living close to our facilities. Rest assured that we will take all measures necessary to minimize the work’s impact on your activities.

What is a rectifier station?

A rectifier station holds equipment that is necessary to supply electrical power to the tracks in the métro. There are several rectifier stations spread out throughout the STM’s métro network.
