Class Action Lawsuit Against Horne Smelter and Quebec Government Authorized by Superior Court

The lawsuit alleges Glencore's emissions exceeded provincial limits by up to 33 times, with claims focusing on damages since 2020 and government regulatory failures since 1979.

  • A Quebec Superior Court judge authorized a class-action lawsuit against Glencore's Horne smelter and the Quebec government for emissions affecting residents in Rouyn-Noranda.
  • Plaintiffs allege that the smelter's arsenic emissions exceeded provincial standards, putting residents at higher cancer risk, according to a 2022 report by Quebec's public health institute.
  • The lawsuit includes claims for damages potentially exceeding $315,000 for each affected member and criticizes government actions since 1979.
  • Justice Daniel Dumais acknowledged evidence of contaminants exceeding norms and cited the 2022 report linking exposure to arsenic and cadmium to increased cancer risk.
