Sitting at the junction of Châteauguay and Léry, the area around the Ruisseau Saint-Jean (stream) is an extremely diverse natural site. To begin, it is partly composed of a major multispecies spawning ground in a floodplain, one of the last natural spawning grounds of Saint-Louis lake. As such, it is an ideal breeding site for many fish species. The site is also home to several species of rare plants. It is actually one of the only protected areas, with the Marguerite-D’Youville wildlife sanctuary and the Fernand-Seguin ecology centre where you can find cockspur hawthorn, a rare plant found almost exclusively in the Châteauguay area. Lastly, birds also flock to the area in great numbers to nest and feed, as do various mammals, reptiles and amphibians. Close to 70 hectares of land surrounding the Ruisseau Saint-Jean are now protected in perpetuity because of a notarized conservation agreement.
The Parc de la Commune extends along the western branch of the Châteauguay river and faces Île Saint-Bernard. It features a one-kilometre multipurpose path, a grassy area and a playground for children. During the fishing season, the spot is especially popular with recreational anglers. The Parc de la Commune is part of Châteauguay’s municipal parks.
