Algoma Steel's Next Chapter

Commissioned in 1975, Blast Furnace No. 7 was once the largest blast furnace in the British Commonwealth. For five decades, it has supplied the steel behind critical projects and applications across North America.

Today, we began the decommissioning of Blast Furnace No. 7, continuing the work which began last week to sunset our cokemaking operations. This includes Coke Battery No. 7, built in 1959; Coke Battery No. 8, built in 1967; and Coke Battery No. 9, built in 1978.

Together, these facilities formed the backbone of Algoma Steel’s integrated steelmaking operations for generations. Their decommissioning marks the end of an era in our history as an integrated steel producer and the beginning of a new chapter.

Algoma Steel is now producing steel exclusively through Electric Arc Furnace (EAF) steelmaking, reflecting a fundamental shift in how we make steel and the future we are building.

To everyone who contributed to Algoma Steel’s integrated steelmaking history—thank you.
