As it is the case with neighboring municipalities, metallurgy plays a significant role in the town's economy. The Sorel-Tracy based QIT et Titane has a facility which occupies the western part of the town, while the eastern part of the town is essentially home to the Les Forges de Sorel company. This leaves the central part as the only portion of the town that is fully residential.
The population of Saint-Joseph-de-Sorel was 1,677 as of the Canada 2011 Census.
