    This project represents an investment of $9.8 million in 2022 to upgrade the underground and surface infrastructure, improve pedestrian safety and facilitate bicycle travel.

    An information meeting was held in 2021 during which a full project presentation was given to area residents.

  • The Ville de Châteauguay will begin the demolition and reconstruction of the low wall along the école Marguerite-Bourgeois parking lot located in the area of the boulevard D’Youville and rue Principale. This work will be carried out from Monday, August 8, until September 2022.

    The project includes:

    • The relocation of the flower bed;
    • The removal and replacement of the staircase with a sidewalk along the parking lot for universal access;
    • Removing and replacing the low wall with a vegetated berm;
    • The addition of bushes and trees.

    Pedestrian access to City Hall will be affected during the construction period. We invite citizens to follow the proposed detour route and to use the sidewalk on the side of église Saint-Joachim, located on boulevard D’Youville.

    During this period, the traffic lanes will remain open. However, the lane along the construction site will be slightly reduced in order to install a temporary concrete wall. Slowdowns are to be expected in this area.

  • Expansion of the École de formation professionnelle and école Louis-Philippe-Paré

    Total investment: $340MM

    Schedule: May 2021 to September 2024

    The phase one of the reconstruction and expansion work at the École de formation professionnelle and École Louis-Philippe-Paré began in May 2021 with the construction of a new synthetic field, scheduled for completion in December 2021. In July 2021, work began on the redevelopment and expansion of the building, which will increase capacity to 2,512 students from Secondary 1 to Secondary 5. The school will eventually benefit from several collaborative and collective spaces, 12 science laboratories, 14 arts spaces, as well as 10 sports facilities, two palestres and a multisport field outside. In addition, a multipurpose auditorium with a capacity of 750 seats will be added and will allow the Châteauguay citizens to benefit from an additional performance hall on the territory.

    Yellow:  perimeter of the site. Green: site of the future synthetic field. Blue: parking of the Sportplex to use in case of overflow. Red: temporarily reduced parking spaces. Purple: a path to safely travel between cars parked at Sportplex and schools.

    Impact of the work

    For the safety of the public, the worksite safety measures may sometimes result in hindrances on roads, bicycle paths, parking lots and properties located within the power line right-of-way. These intermittent hindrances may last anywhere from ten minutes to three days.

    The work is not ever expected to lead to a power outage. If such a situation were to occur, however, the affected residents would be informed by an automated telephone messaging system.

    Mitigation measures

    A traffic plan has been established, in cooperation with the municipal authorities, to facilitate the movement of cars, cyclists and pedestrians.

    The work will be carried out during off-peak hours.

    When detours are required, appropriate signage will be in place.

    With few exceptions, access to homes will be maintained

    The work will comply with the environmental standards in effect.

  • New Water Parks

    New water parks were built in four city parks between April and June 2021. This investment of nearly $2 million will increase the number of water parks available in the territory for the enjoyment of residents in several neighbourhoods.

    Parks slated for new water parks:

    More information on this major project is forthcoming. You will soon find this information on the Past and Upcoming Major Projects.

    New Play Equipment

    These new facilities in three of our parks added for the enjoyment of children, represents an investment of $150,000.

    Parks slated for these improvements:

    For more information about this major project, go to Past and Upcoming Major Projects.

    Naturalization of Parks

    The naturalization of our parks consists of reducing maintenance interventions to a minimum to give free rein to natural vegetation. The horticultural teams will sow new species of flowers and plant trees and shrubs all summer long to maximize the vegetation of the banks.

    Parcs slated for these measures:

  • From July 18 to August 12, 2022, the Ville de Châteauguay carried out repair work on boulevard D’Anjou, between boulevard Saint-Jean-Baptiste and rue Thibert.

    The project involves:

    • Sawing work of storm sewer services and water mains;
    • Maintenance work on sewer manholes, catch basin grates and aqueduct covers;
    • Plane work for roadway levelling, which could temporarily limit access to residences and businesses during the day;
    • Paving work of the roadway.

    Final section of boulevard D’Anjou: Preliminary work in 2023

    The portion of boulevard D’Anjou between rue Normand and the Arthur-Laberge Bridge has undergone minor repairs as the City will be replacing the sewer lines in 2024. Preliminary work will begin in 2023. To avoid repaving the same section in a short period of time and for cost reasons, only the damaged areas were repaired on a spot basis.

    The second phase of this project including the complete paving of the section will begin in spring 2024.

  • Street resurfacing

    Resurfacing work will be carried out from June to October 2021. The schedule may change depending on the weather. The completion of this street rejuvenation plan will cost $3.5 million.

  • During the months of April to November 2021, vegetation control work will be carried out on the easement located on the City’s lands. The objective of these interventions is to promote compatible vegetation by eliminating vegetation that is incompatible with the operation of the system, which could represent a feasibility and safety issue. The purpose of this program is to promote low and sparse vegetation in line rights-of-way.

    The work to be carried out includes:

    • Cutting of mature trees within the right-of-way.
