Volunteers across Quebec have been invited to take part in a province‑wide cleanup of the Saint Lawrence River and its watershed from August 6 through August 21, 2026. The effort, organized by the group Expédition Saint‑Laurent, marks the third edition of its riverbank cleaning campaign and will span locations from Montreal in the west to Baie‑Comeau in the east.
Expédition Saint‑Laurent is coordinating the initiative to address litter accumulation along the river’s banks and tributaries. Participants are asked to gather in designated areas, collect debris, and remove waste that threatens the water quality and surrounding ecosystems. The organization emphasizes that removing litter is essential for improving the environmental health of the river system, which supports both wildlife and local communities.
The campaign’s timeframe of two weeks provides a structured window for coordinated action. Cleanup sites will be set up in multiple municipalities along the river’s course, allowing residents, students, and other community members to join local teams. While the exact number of volunteers has not been disclosed, the program’s third iteration suggests a growing public interest in river stewardship.
Authorities and environmental groups have highlighted the Saint Lawrence River’s significance as a major waterway for commerce, recreation, and biodiversity. By targeting both the main channel and its tributaries, the cleanup aims to reduce pollution sources that can affect downstream water quality and habitat conditions. The initiative also aligns with broader provincial efforts to protect natural resources and promote sustainable land‑use practices.
Organizers encourage participants to bring appropriate gear, such as gloves, sturdy shoes, and reusable bags, to safely collect and transport waste. Safety guidelines will be provided on-site, and volunteers will be asked to follow local regulations regarding waste disposal. The cleanup concludes on August 21, after which collected material will be sorted for recycling or proper disposal.
The third Expédition Saint‑Laurent cleanup reflects an ongoing commitment to preserve the Saint Lawrence River’s ecological integrity, inviting Quebecers to contribute directly to the health of one of the province’s most vital natural assets.
