Brossard is a suburb in the Montérégie region, adjacent to Longueuil. There’s nice running on a dedicated multi-use path of nearly 8km passing through a linear park, along a lake, and several small parks along the Saint Lawrence River. Bonus: linear park section is lit at night!

Start in central Brossard at Parc de la Terre. There’s a paved multi-use path running through several narrow parks, forming a linear park through this residential area. It’s 3.5 km south to Parc Radisson. From there, continue south. There’s a nice ~1 km along the Lac de La Citière (lake), and then another ~1 km to Centennial Plaza. These are parks on the south side of Highway 15. You can add another ~1.5 km of very scenic paths along the St. Lawrence River by crossing over the pedestrian bridge at Centennial Plaza, featuring some great views at the Point at Bassin scenic spot.

For a shorter run, do just the lake & riverfront sections.
