Québec Passes Bill Supporting Horne Smelter Operations, Allowing Glencore to Resume Environmental Investments

Published: Jun 15, 2026 10:03
Glencore Canada has welcomed the Québec government's passage of Bill 11, which establishes a stable regulatory framework for the Horne Smelter through 2033. The legislation extends the timeline for compliance with stricter arsenic emission standards, providing greater certainty for ongoing operations and investment planning. As a result, Glencore plans to gradually resume approximately C$300 million in environmental improvement projects that had previously been placed on hold due to regulatory uncertainty. The company said these projects are expected to position the Horne Smelter among the world's leading copper smelters in terms of environmental performance. Horne remains Canada's only operating copper smelter and plays a strategic role in the country's critical minerals and refining supply chain.
