Ten-Year Dredging Program

To ensure the port’s accessibility, the basin has to be routinely dredged to reach safe depths for navigation and to ensure the port’s economic activities can continue, i.e. the navigation of commercial vessels.
The ten-year program aims to maintain the depths required through regular dredging over the period of ten years.

The Port


The Port of Gros-Cacouna plays a strategic role in the region’s commercial and economic development.

It’s a deep-water port, open year-round whose primary activity is transshipping goods for companies in the peat, wind turbine parts, wood products, special projects for Northern Quebec and bulk goods (including de-icing salt for roads) sectors. Cacouna’s industrial park is opposite the port.

This strategic location is a huge asset for companies whose activities require proximity to a deep-water seaport that is operational year-round.

Social and Economic Impacts


2,000 people employed directly through the offloading of perlite.


Supports 3,000 jobs in the timber industry.


Three wind farm projects in the Bas-Saint-Laurent region.
The port is a future hub for incoming wind turbine parts.



Protection of beluga whales.


The territory is shared with the Wolastoqiyik Wahsipekuk First Nation.


 The port is susceptible to natural sedimentation which is common in this section of the St. Lawrence.



Remove a portion of accumulated sediment and maintain safe water depths to ensure the continuation of the port’s economic activities

Carry out maintenance dredges over a period of 10 years

Update the port’s infrastructure to ensure its longevity and development

The Consultation Process

Gros-Cacouna’s port infrastructure is located in close proximity to a populated area and sensitive areas for marine wildlife and flora. The SPBSG is committed to maintaining harmony with coastal communities and the wildlife and flora habitats around the port.
Furthermore, the SPBSG would like to establish a structured approach to maintaining a positive relationship with the community throughout the project.
This will involve consulting with the project’s stakeholders in order to notify them of the issues with the current infrastructure, the proposed solutions, the anticipated impact and the planned mitigative actions. The consultations will also be an opportunity to hear and take into account the stakeholders’ concerns in order to adapt the project to Cacouna’s social, economic and environmental context.
