A Quebec mining company, ArcelorMittal, is fined $100 million under Canada’s Fisheries Act for polluting fish-bearing waters, according to reports from Canadian outlets. The penalty is described as the harshest ever imposed under the Fisheries Act, based on statements cited from the Public Prosecution Service of Canada. The charges relate to impacts on waterways that support fish, and the case centers on alleged pollution associated with the company’s activities in Quebec. While the outlets provide the same overall outcome and the size of the fine, they frame the decision in terms of the federal prosecution’s position that the penalty sets a record under the fisheries enforcement regime. The reports do not indicate any alternative amounts or competing explanations for the court’s decision, and they present the fine as the result of enforcement action by the federal legal authorities. The coverage collectively treats the $100-million sanction as the core development, emphasizing its record-setting character within Fisheries Act prosecutions.
