Redevelopment of Rimouski’s Port Infrastructure

The project aims to consolidate part of the port infrastructure, which is in an advanced stage of deterioration, limit environmental damage and protect ecosystems.

The planned work will play a major role in protecting the east wharf and ensuring the longevity of the port’s commercial, fishing and scientific research activities.

Furthermore, the project will create a unique space for the population of Rimouski, giving them access to the St. Lawrence.

The port


The Port of Rimouski is a commercial, scientific and tourist port. Its main activities include:

  • Commercial port of call for transshipping goods.
  • Ferry and supply ship services to the North Shore and Lower North Shore.
  • Commercial fishing.
  • Home harbour and port of call for research vessels.
  • Tourist attraction area due to its proximity to downtown Rimouski and recreational fishing on the fishers’ wharf.

Social and Economic Impacts


The research vessel welcomes close to 200 researchers from around the world every year.


Over $100 million in annual economic benefits


Close to 1,000 people employed directly and indirectly through port activities



Major deterioration of the west causeway and transverse causeway, making them unusable.


High risk of fracture and collapse of the above-mentioned causeways, which poses a significant environmental challenge but could also affect operations on the east causeway.


Recurring dredging required at the port of Rimouski to reach safe depths for navigation and thus ensure the continuation of the port’s economic activities.


The port has a recreational and tourist attraction, due to its proximity to the city center and the history of recreational fishing, which creates conflicts of use between the population and commercial port activities.


The potential for commercial development is limited.



Maintain safe port operations

Improve relations between users

Consolidate the west and transverse wharves.

Develop the scientific vocation of the port

Establish a ten-year dredging program to allow maintenance dredging for the safety of port operations.

Create a space for the population of Rimouski, giving them access to the St. Lawrence from the port.

Anticipated Timeline


Development of a concept for the development of a citizen space

The Société portuaire du Bas-Saint-Laurent et de la Gaspésie hereby gives notice that an application has been made to the Minister of Transport, pursuant to the Canadian Navigable Waters Act for approval of the work described herein and its site and plans.

The Consultation Process​

Rimouski’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 Rimouski’s social, economic and environmental context.
