Stelco Holdings Inc. is a Canadian steel company based in Hamilton, Ontario. Stelco was founded in 1910 from the amalgamation of several smaller firms. It continued on for almost 100 years, until it filed for bankruptcy in 2007 and was bought by U.S. Steel. In 2016, the company was sold to Bedrock Industries of the United States, which took the company public. The company made its debut on the Toronto Stock Exchange on Nov. 3, 2017. The Hamilton plant has not produced steel since 2011, but its coke ovens and cold rolling finishing works remain in operation. The company employs about 750 people in the Hamilton plant and 1,400 in Nanticoke, Ontario at its greenfield facility Stelco Lake Erie Works. Wikipedia
