ArcelorMittal Dofasco, also known as ArcelorMittal Hamilton or ArcelorMittal Flat Carbon Steel Canada, is a 4700 TTPA steel plant in Ontario, Canada.[1] ArcelorMittal Dofasco operates a blast furnace (BF), a basic oxygen furnace (BOF), and an electric arc furnace (EAF).

The ArcelorMittal Dofasco plant began operating in 1912. The plant was purchased by ArcelorMittal in 2006 (the largest steel company in the world), who outbid a German steelmaker rival, ThyssenKrupp.

Environmental Concerns

In 2014, the company paid around half a million CAD after pleading guilty to violating air quality standards in 2012.[2] In 2015, an instrument failure released a large amount of iron oxide dust into the atmosphere.[3] In 2018, another large black plume of dust was released from the plant. The company was fined more than $268,750 CAD in 2021 for this incident.[4]


In July 2021, an 2400-thousand tonne expansion to the ArcelorMittal Dofasco plant was proposed, with an anticipated completion date of 2028. The expansion represents a 1.756 billion CAD investment (with 400 million CAD coming from federal government support).[5] The new extension is meant to be a transition away from BF-BOF furnace steelmaking to the greener DRI-EAF production; it should reduce emissions at the plant by 60%.[6] According to Newswire, this project, along with the Algoma Steel project announced on July 5, 2021, will reduce Canada's greenhouse gas emissions by up to 6 million tonnes per year.[5]
