Successively owned by the Canadian British Aluminum Company, the Reynolds Metals Company and Alcoa (since 2000), the smelter was built and then expanded on four different occasions between 1957 and 1991.


Today, the Baie-Comeau Smelter 480 cells have a production capacity of 295,000 metric tons of aluminum. To better take advantage of the demand for aluminum in the automotive sector, an investment of almost $30 million is now underway in the Foundry and Casting sectors of the plant.


The smelter is Baie-Comeau’s largest employer and its employees are highly involved in the community. It supports a number of organizations, including the Manicouagan-Uapishka World Biosphere Reserve. The plant was recognized as part of the St. Lawrence Action Plan for its work in industrial wastewater treatment. It also received the Mérite québécois de la sécurité civile Award for helping create a stakeholder emergency readiness training program for the Manicouagan regional county municipality.


The Baie-Comeau Smelter is a Distinction member, the highest level, of Hydro-Québec’s Energy Saver’s Circle, a network of energy efficiency leaders.
