That's according to the Quebec Professional Association of Real Estate Brokers (QPAREB), which released its first report of 2023 on January 5. The association gave a snapshot of home price trends in the five zones that comprise the metro area: Montreal Island, the North and South Shore, Vaudreuil-Soulanges and Saint-Jean-sur-Richelieu.
