    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.

    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.

    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:

  • 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.

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