The Parc Marcel‑Laurin wooded area is an exceptional natural site located in the borough of Saint‑Laurent, protected and enhanced for more than fifteen years.

Covering an area of 15.97 hectares, the Parc Marcel‑Laurin wooded area represents a remarkable natural environment bordering residential and industrial sectors.

It offers visitors privileged access to diverse flora and fauna, as well as a 2.1‑km pedestrian trail, including the pathway leading to the Brunante basin. The total area, including Parc Marcel‑Laurin, reaches 37.4 hectares, making this ensemble a key green space for the borough of Saint‑Laurent and the Montréal agglomeration.

Since 2005, the borough of Saint‑Laurent has ensured the protection, conservation, and enhancement of the wooded area, in collaboration with the Comité écologique du Grand Montréal (CEGM) and with the support of partners from the environmental, institutional, and corporate sectors.

A protected natural site of metropolitan significance

The Parc Marcel-Laurin woodland is the first municipal natural site classified as Category A to be listed in the Register of Protected Natural Areas of the Montréal Agglomeration. This designation, granted in December 2010, highlights the site’s ecological value and biological richness, as well as the borough’s strong commitment to the protection of natural environments.

A key link in Saint‑Laurent’s biodiversity corridor

The Parc Marcel-Laurin woodland is an integral component of the corridor de biodiversité de Saint‑Laurent, which connects several ecological hubs across the territory, including the Cavendish — Raymond‑Lasnier — Beaulac — Poirier wooded area, the Bois‑de‑Liesse and Bois‑de‑Saraguay nature parks, as well as Brook Creek. This corridor promotes ecological connectivity for flora, fauna, and residents alike.

Flora and natural environments

The wooland supports a rich plant biodiversity comprising more than 191 species, including trees, shrubs, and herbaceous plants. Its forests, wetlands, and fallow lands play an essential role in sustaining local biodiversity, particularly for pollinators and numerous wildlife species.

A site recognized for birdwatching

Thanks to the diversity of its habitats, the wooded area and the Brunante basin are recognized as sites of ornithological interest. Numerous bird species can be observed throughout the seasons. Amateur birdwatchers are encouraged to record their observations in the eBird Québec database, thereby contributing to scientific monitoring efforts.

Educational activities and site enhancement

Tree plantings, community clean‑up activities, and nature discovery programs are offered throughout the year, fostering public awareness and encouraging community engagement.

Partners and Donors

The enhancement of the Parc Marcel-Laurin woodland is made possible through the collaboration of the Éco‑quartier de Saint‑Laurent and the Comité écologique du Grand Montréal (CEGM). Its preservation and ongoing development also rely on the commitment of valued partners and donors, whose support plays an essential role in protecting this exceptional natural environment.
