The South Shore (Rive-Sud) refers to a large suburban region located south of Montreal, across the St. Lawrence River. It includes many cities and towns such as Longueuil, Brossard, Saint-Lambert, and Boucherville. The area is known for its family-friendly neighbourhoods, more spacious housing, and growing commercial developments. With easy access to Montreal through several bridges and the REM light-rail network, the South Shore offers a convenient suburban lifestyle while staying closely connected to the metropolitan core.
