Built in the mid-1970s, the wharf at the Jacques-Cartier marina, in Hull, is an important access to the Ottawa River from Jacques-Cartier Park, in Gatineau (Hull sector).

Within the next two years, the NCC will undertake repairs to address some structural issues at the wharf.

About the project

In 2018, emergency repairs were completed on the north side of the wharf to address large underwater voids below the wharf that were creating sinkholes. Recently, a new sinkhole was observed under the wharf, prompting further investigation. Following the 2020 investigation, similar voids below a section of the wharf were observed.

The goal of this project is to address the issues related the existing sinkhole under the lower portion of the wharf, and to undertake repairs on the upper portion of the wharf. This rehabilitation will improve overall safety for the wharf’s tenants and users.

Process and Timeline

Phase 1

Winter 2021

Repair work is needed to address the existing sinkhole problem under the lower portion of the wharf, which will involve closing the area. The work, which is expected to take about two weeks, includes the following:

  • excavation
  • concrete work
  • asphalt (in early spring 2021)

Phase 2

Summer 2021 / winter 2022

Work on the upper portion of the wharf will include the following:

  • repair of the existing voids in the wall and under the ground
  • excavation and concrete work
  • asphalt

For security reasons, the upper portion of the wharf will be closed to the public.

This project is part of the NCC’s major infrastructure projects made possible with the Government of Canada’s $52.4-million investment from the 2020 federal budget.
