Work underway at McGill station

Project summary

Since March 2020, major work has begun both inside and outside McGill station.

Duration of the work: March 2020 to spring 2022

Description of the work: Replacement of the waterproofing membrane covering the station’s underground roof, installation of two elevators, construction of a new entrance building, and renovation of three of the station’s six entrance buildings.

Texte important

Since May 25, the worksite on De Maisonneuve Boulevard has moved east, between Robert-Bourassa and Aylmer.

Métro impacts: Several partitions will be installed on the western side of the station. They will temporarily close off two entrance buildings and one of the two accesses to the Centre Eaton de Montréal.

Bus impacts: All bus lines serving the station will have to be rerouted. Some lines will finish their service at Square-Victoria-OACI station.

Progress of repair work around McGill station

The replacement work being done on the waterproofing membrane covering the station’s underground roof is well underway, and nearly 65% of the work is done. This project that involves multiple steps, including soil excavation, removal of the old membrane, surface cleaning and installation of a multi-layer waterproofing system to prevent leaks.

This worksite is also an opportunity for us to continue the construction work on an elevator shaft in the western portion of the station on De Maisonneuve Boulevard.

Increased service: 12 Île-des-Sœurs

Due to ongoing work at McGill station, many residents of Île-des-Sœurs who used to take line 168 Cité-du-Havre downtown are now opting for line 12 Île-des-Sœurs to get to the Green line at De l’Église station. We have increased service frequency with an extra departure in the morning (northbound) and one in the afternoon (southbound).

The frequency of line 12 Île-des-Sœurs will increase from every 20 minutes to every 15 minutes between 7 a.m. and 9 a.m. and between 4 p.m. and 6 p.m.

The following stops must be relocated due to the closure of De Maisonneuve and the numerous construction projects in the area:

  • 15 Sainte-Catherine
  • 35 Griffintown
  • 61 Wellington
  • 125 Ontario
  • 168 Cité-du-Havre
  • 420 Express Notre-Dame-de-Grâce

Lines 35, 61 and 168 will end their service on René-Lévesque Boulevard at the corner of Union Avenue, while boarding will take place at Square-Victoria–OACI station.

The STM isn’t in the habit of cancelling a number of consecutive stops on one or more bus lines. When we decide to do so, it is as a last resort, after we have analysed all other solutions.

In planning the detours for the lines serving McGill station, we considered the numerous construction sites planned for the area this year. A number of streets will be closed, blocked or reconfigured, and serving McGill station would have required a major, several-minute detour, often through streets clogged with traffic. When we implement this type of detour, the route soon becomes inefficient, and our buses are stuck in traffic for long periods of time. The delay experienced along the detour has an impact on the entire route, and it becomes almost impossible to stay on schedule.

On top of that, riders realize that it is faster to cover the distance on foot. That creates situations where riders ask the driver to let them get off at unplanned locations along the detour. These locations are often not very safe. In addition, we found that it would be impossible to pick up passengers on René-Lévesque Boulevard, as that would block the reserved lane and hinder several other bus lines. We therefore have to go to Square-Victoria–OACI station.

It is also worth noting that last year, during similar work, the same detour was deployed. We implemented a shuttle service to make it easier for people to go to McGill station. However, only a few dozen customers made use of this service. This year, we are adding a stop on the 36 Monk line (eastbound) at the corner of Côte du Beaver Hall and Avenue Viger (stop 52626), as well as a stop on the 75 De la Commune line (southbound) on René-Lévesque Boulevard, at the corner of Côte du Beaver Hall (stop 61657), so that customers do not have to walk down the hill to Square-Victoria–OACI station.

Since March 2, 2020

The entrance hall located at 811 De Maisonneuve Ouest is closed.You will be able to access the station through the entrance building at 2055 Robert-Bourassa.

Since May 11, 2020

Work as started inside the station. The turnstiles on the west side of the station have been completely redesigned to facilitate passenger movements during the work. And the west side of the station is completely closed off.

Since May 24, 2020

The Centre Eaton de Montréal is no longer accessible from the station.

The Espace client located on the west side of the station is closed. Our station agents are offering our full range of services at the fare booth located near La Baie store.

Starting June 28, 2021

The entrance building at 640 De Maisonneuve West will be closed from June 28, 2021 until December 2021. The station will remain accessible via the entrance building at 690 De Maisonneuve West, since it will have reopened.

Plan your trips when leaving the station:

  • Take the Eaton Centre exit to go west on De Maisonneuve Boulevard
  • Take the Union exit to go east on De Maisonneuve Boulevard

Impact on people in the area

The worksite has moved further east since May 25, 2021. This results in the closure of De Maisonneuve Boulevard West between Robert-Bourassa Boulevard and Aylmer Street.

The worksite will intersect Union Street, which will be closed to traffic between Sainte-Catherine Street and Président-Kennedy Avenue.

A westbound lane will be open on De Maisonneuve Boulevard, between Robert-Bourassa Boulevard and McGill College Avenue.

Businesses and office towers will remain accessible for the duration of the work.

The waterproofing membrane protects the station from water infiltrations. It covers the station’s underground roof and is therefore located underground. McGill station’s membrane dates back to its initial construction and has reached the end of its useful life.

Underground, the station is as wide as De Maisonneuve Boulevard and 150 metres long. It’s impossible to keep the road open given the scope and complexity of the work. Major work like this also requires lots of space for moving machinery around. We will also have to deal with massive conduits (electrical power and others), which are particularly dense and complex downtown. Once again, we will need a lot of space to do the work around them.

Different criteria influence the order in which elevators are installed at métro stations, such as ridership, proximity to certain services or institutions and technical complexity. This work is part of the STM’s goal to have 41 universally accessible stations by 2025.

Coordinating with the other projects in the area is very important to us. We have coordinated with the Réseau express métropolitain (REM) project and the Ville de Montréal’s projects on Sainte-Catherine. The traffic plan was developed with all stakeholders in the area.

Yes. Once the membrane is replaced, we will begin the major renovation of the station’s mezzanine.

Did you know?

When the station was built in the 1960s, McGill station was known as a prestigious station. This was why it has escalators that go right down to the platforms and walls covered with travertine tile, a high-end product imported from Italy.
