Sault Ste. Marie, Ontario

Algoma Steel is laying off 300 employees beginning Monday, March 24, 2026. The layoffs are partially attributed to tariffs impacting the steelmaking operation in Sault Ste. Marie, Ontario.

Algoma Steel laid off approximately 1,000 steelworkers in March 2026 due to U.S. tariffs and the company's transition to electric steelmaking. The layoffs significantly impacted the Sault Ste. Marie region and eliminated potential job creation opportunities tied to a failed South Korean submarine contract bid.

Algoma Steel is laying off 1,000 workers at its Sault Ste. Marie facility in March 2026. The United Steelworkers Union and Canadian Skills Training and Employment Coalition have launched the POWER Action Centre to provide employment support, training advice, and peer-to-peer assistance to affected employees.
