Take part in the shoreline cleanup

On Saturday, September 9, Rosemerites are invited to participate in a massive shoreline cleanup operation known as the Grand nettoyage riverain, taking place along the Mille Îles and Du Chêne Rivers and Lake of Two Mountains. The goal of these efforts, which will involve the administrations and residents of Blainville, Boisbriand, Deux-Montagnes, Laval, Lorraine, Pointe-Calumet, Rosemère, Sainte-Marthe-sur-le-Lac, Sainte-Thérèse and Saint-Eustache, as well as the Conseil des bassins versants des Mille-Îles (COBAMIL) and the Parc de la Rivière-des-Mille-Îles, is to protect aquatic ecosystems by picking up litter from the banks of local waterways. 

“Preserving our green spaces is an ongoing priority for Rosemère,” said Mayor Eric Westram. “This shoreline cleanup is an opportunity to drive home the need to safeguard the precious resource that is the Mille Îles River. By working together, we can have a real impact on the environment — something that unites us all.”

How to sign up and take part

Anyone interested in joining Rosemère’s shoreline cleanup is asked to register by email at, indicating the names and ages of all the people in their party. Participants will rendezvous at the Sainte-Thérèse water treatment plant at 111 Labelle Boulevard at 9 a.m. The operation will wrap up at noon. 

The event will be held rain or shine. Participants should come wearing long pants and closed-toe shoes or rubber boots to reduce the risk of coming into direct contact with harmful plants or animals.

“Our organization strives to protect, conserve and showcase the Mille Îles River and its tributaries, so we are proud to be participating in this wonderful event and showing our support for this natural treasure and those who live nearby,” said Christine Métayer, Executive Director of Éco-Nature, Parc de la Rivière-des-Mille-Îles. “We’d also like to take this opportunity to thank all our partners for their invaluable help.”

“Holding and taking part in shoreline cleanups on the North Shore is part of who we are here at COBAMIL,” said Executive Director Raphaël Goulet. “It’s so gratifying to watch our communities coming together to restore our aquatic ecosystems and learn how it important it is to lessen our impact on nature. We look forward to doing it again in the years to come!”
