Located on a rocky promontory overlooking the majestic St. Lawrence River, the Baie-Comeau Smelter has an annual production capacity of 295,000 metric tons of aluminum. 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. In addition, the Söderberg cells were upgraded in the early 1980s. 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 on 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 an Elite member of Hydro-Québec’s Écolectrique network.
