Canada’s Industry Minister Mélanie Joly confirmed discussions with Rio Tinto to support domestic aluminium production after the US imposed 50% tariffs on steel and aluminium imports. Prime Minister Mark Carney warned that Ottawa will adjust its counter-tariffs by July 21 if no agreement is reached. Rio Tinto’s Saguenay–Lac-Saint-Jean operations include five smelters, an alumina refinery, six hydropower plants and a research centre; it holds 40% of Aluminerie Alouette. Alouette’s recent Hydro-Québec deal commits CAD 1.5 billion ($1.6 billion) to modernizing its operations, securing flexible electricity pricing to weather low aluminium prices and share gains when markets strengthen—enhancing both power certainty and cost competitiveness for Rio Tinto.
