Chabanel mechanical ventilation station

Construction project : future Chabanel mechanical ventilation station

Project summary

The rectifier station on Berri Street houses a mechanical ventilation station (MVS). This MVS has reached the end of its useful life and needs to be replaced with a new dedicated building, the Chabanel MVS. The new equipment is necessary for us to meet metro ventilation standards between Sauvé and Crémazie stations.

The existing rectifier station will also be updated with a refurbished building envelope. Once completed, the exterior will be more visually appealing.


Duration of the work: October 11, 2022 to summer 2025 

Description of the work: Expansion of existing rectifier station to integrate a new mechanical ventilation station

Métro impacts: No

Bus impacts: No

Impact on customer trips

This project has no impact on customer trips.

Impact on local residents

Impact on traffic

Berri Street:

There will be a worksite on Berri Street near Chabanel Street, but it will not require any lane closures.

Two lanes of traffic will still be open during peak hours, as well as one lane during off-peak hours.

Chabanel Street:

During the work, Chabanel Street will be a one-way street going west between Lajeunesse and Berri.

At the Berri and Chabanel intersection, a portion of the northeast sidewalk will be blocked during the work. Pedestrians can use the west sidewalk in this area.

Please note that the work will at no time block pedestrian access to homes.

This type of construction work requires major excavation. This may cause noise, vibrations and dust. The worksite will partially block Berri Street near the intersection with Chabanel Street. The alleyway between Lajeunesse and Berri will remain open.

To reduce the negative impact on residents, we will implement mitigation measures that are specific to the worksite and to each stage of the work. For example, we will favour the use of electric equipment, which generally emits less dust and noise than other types. Construction work will be limited to the times of day allowed by municipal by-laws, and local access to Berri Street will be maintained at all times. Work will begin in October 2022 and will take about three years to complete.

Once the work is complete, the mechanical ventilation station will comply with all City of Montréal noise by-laws. Huge noise suppressors will mitigate the noise from the fans, installed below ground level, to ensure quiet for residents living nearby. The noise will not exceed 50 decibels, a level comparable to that of a household dishwasher.

The contractor is responsible for removing the snow from the right-of-way of the worksite and from the sidewalk on the east side of Berri Street, which faces the worksite. The borough oversees the snow removal for the sidewalks and streets, and we will contact them to ensure that our worksite does not interfere with these activities. As for the alleyway, we will ensure that it will be cleared of snow as usual.

The alleyway is not part of the worksite. It will remain accessible to residents and cars at all times.

For now, blasting isn’t planned. Should the contractor decide to use this method in the next phase of the work, additional information will be sent to inform residents.

Work will mainly be carried out during the week, within the hours authorized by the borough, from 7 a.m. to approximately 4 p.m. From time to time, we could work outside the usual hours, if necessary. For example, this could be the case for concrete pouring, which cannot be paused halfway. Weekend work might also be performed to make up for delays.

The contractor is responsible for the waste collection of residences near the worksite. They will return your containers to the front of your home after collection. Remember to properly label your container with your address.

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

Learn more about the project

A mechanical ventilation station is an infrastructure located between two métro stations that is equipped with two fans designed to extract hot air from the métro network through inlets fitted with air vents. Ventilation stations built for the original métro network extract around 60,000 cubic feet of air per minute, while the new ventilation systems extract around 240,000 cubic feet per minute. Huge noise suppressors mitigate the noise from these fans to ensure quiet for residents living close to a ventilation station.

Mechanical ventilation stations serve three essential purposes:

Comfort ventilation
Regulates the ambient temperature and supplies fresh air for transit users by exchanging air from the outside with air inside the métro network.

Night-time ventilation
Ensures a supply of fresh air for night workers carrying out routine maintenance.

Emergency ventilation
In the event of an incident, controls smoke and provides a safe evacuation route for passengers via the nearest métro station and ensures unobstructed access for emergency first responders.
