The Contractor will be on site until Friday, April 2, 2021 inclusively to carry out the corrective work requested by the City. Please consider that traffic in this area (Edward Sud and boulevard St-Francis intersection) will be slowed down due to the work in progress.

  • 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.

    To find out more: Hydro-Québec/vegetation

    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.
