Algoma Steel Group Inc. is a Canadian steel producer headquartered in Sault Ste. Marie, Ontario, with approximately 2.8 million tons of annual liquid steel production capacity. The company produces hot-rolled and cold-rolled steel products and is Canada's only producer of discrete plate. Algoma is transitioning from traditional blast furnace operations to electric arc furnace steelmaking, with its second EAF unit nearing completion in 2026. The company's large industrial site and substantial electricity infrastructure have also made it relevant to emerging data center development in the Sault Ste. Marie region, including a proposed large-scale AI data center project involving Red Jar Energy Partners.
