  • Location: 800, Montée de la Pomme d'Or, Contrecœur (Quebec), J0L 1C0, Canada
  • Coordinates (WGS 84): 45.835148, -73.254957 (exact)

Background

ArcelorMittal Montreal consists of two steel plants, ArcelorMittal Contrecoeur East and ArcelorMittal Contrecoeur West, a DRI plant, a bar mill, wire rod mill, and steel recycling center at the the Quebec location. Two additional wire mills in Montreal (St. Patrick wire mill) and Ontario (Hamilton-East wire mill) are also operated under the ArcelorMittal Long Products Canada company.[1]

ArcelorMittal has committed to net-zero emissions by 2050 and is developing its “XCarb™” branded initiatives as part of its decarbonisation strategy.[2] In 2022, the plant successfully tested the use of green hydrogen in the DRI process[3].

In April, 2025, a fire broke out on the grounds of the ArcelorMittal site in Contrecoeur, raising concerns for air pollution.[4]

In May, 2025, the Environment and Climate Change Canada (ECCC) laid 200 charges under the Canadian Fisheries Act against ArcelorMittal Canada Inc., for alleged illegal deposits of “deleterious substances” into fish-bearing waterways (in the Fermont/Fire Lake region of Québec) between 2014 and 2022.[5]
