Past and Upcoming Major Projects

The city is continuing its efforts to offer the public a high-quality road network, lasting infrastructures and a pleasant living environment. In addition to periodic work, a number of major projects take place each year across the territory. Here is a list of upcoming major projects and a summary of those that have just been completed.

Ongoing and upcoming major projects

A variety of projects are currently under study. As soon as the details are known, they will be unveiled here.

  • Archaeological inventory work underway and rehabilitation work temporarily suspended

    The City is temporarily suspending the repair work on the heritage components of île Saint-Bernard to assess the impact of the work and determine whether further archaeological interventions are necessary. The current excavations will be visually inspected.

    See the press release

    Archaeological inventory work

    Archaeological inventory work is planned according to the following schedule. Two archaeologists from Archéotec and two archaeological technicians from Kahnawake will be on site.

    Work will resume afterwards, probably around mid-August. When work resumes, the excavations will be completed and the archaeologists will return to ensure that the archaeological heritage is preserved.

    Mobilisation, trench marking and work planning

    June 15 and 16, 2021

    Excavation of trenches with machinery and start of archaeological work

    June 17, 18 and 21, 2021

    Archaeological work with manual excavations. This work could be extended if necessary in the event of significant finds.


    Au terme de ce projet, le moulin, l’escalier, la grotte, la croix et le cimetière seront remis en état afin d’en assurer la pérennité et d’améliorer l’expérience des visiteurs. Ces cinq vestiges seront également illuminés et constitueront un parcours historique à découvrir. Grâce à la participation d’archivistes des Sœurs Grises de Montréal et à la Société du Musée du Grand Châteauguay (SMGC), cinq panneaux d’interprétation mettront en valeur les attraits et
    relateront leur histoire.

    Awarded to Construction Valrive, the contract to repair the heritage elements should be completed by mid-July. The operations will begin with masonry work in the grotto and with the complete reconstruction of the grand staircase, which will be brought back to current standards while retaining its original cachet. The cemetery will then be embellished with landscaping, including paths and more vegetation. The cross’s base will be solidified, and the mill will be the last element to undergo a beautiful rejuvenation, particularly with the repair of its masonry.

    This $1.5 million project is being carried out in part thanks to the Fonds d’appui au rayonnement des régions from the Ministère des Affaires municipales et de l’Habitation, as well as the financial participation of the Grey Nuns of Montréal. Ville de Châteauguay, for its part, assumes nearly half of the costs. Héritage Saint-Bernard, acting as site manager, is collaborating on the project, as is the Société du Musée de Grand Châteauguay.

    Impact on the public

    Ville de Châteauguay will try to minimize the impact of the work on visitors to Île Saint-Bernard. Access to the site will still be possible. The work will take place during the week, between 7 a.m. and 6 p.m. The asphalt path and green spaces will be accessible, but the site’s tranquillity will be disturbed during the work. A portion of the grassy area behind the mound will be reserved for workers and their equipment, and access will be restricted. Also, the areas under construction will be barricaded.The public will be requested to keep a distance to ensure everyone’s safety. Information panels will indicate the duration of the work and the safety instructions to be observed.


    Note: dates will be revised due to the suspension of the rehabilitation work. The resumption of work is expected to take place around mid-August.
