Glencore Halts Major Investment at Horne Smelter Over Emissions Dispute

On February 3, 2026, Glencore announced the suspension of nearly $1 billion in planned investments at the Horne Smelter, Canada’s largest copper metal-producing facility located in Rouyn-Noranda, Quebec. This decision follows the company's inability to secure regulatory certainty from the provincial government regarding emissions reduction requirements. Glencore had aimed to modernize the smelter to comply with Quebec's stringent arsenic emission targets, which mandate an annual average of 15 nanograms of arsenic per cubic meter (ng/m³) in ambient air.

The company indicated that it would also scale back investments at its Montreal facility in the medium term. Glencore's Chief Operating Officer, Marc Bédard, stated that the firm had "worked in good faith" to reach an agreement but found that the necessary conditions for proceeding with the investment were not met. The smelter is currently operating under its existing authorization, but without planned upgrades, it risks failing to meet emissions targets set to take effect in March 2027.

The Horne Smelter has been operational since 1927 and has faced scrutiny over its emissions in recent years. Between March 16, 2023, and March 15, 2024, the facility averaged 45 ng/m³ of arsenic, a significant reduction from previous levels. However, the smelter's emissions have led to legal challenges, including a class-action lawsuit authorized by the Quebec Superior Court. Residents of Rouyn-Noranda allege that the smelter has violated environmental standards and caused disturbances in the community, holding both Glencore and the provincial government accountable for inadequate oversight.

In its announcement, Glencore emphasized the importance of stable regulatory conditions for its operations. The company described it as "irresponsible" to authorize investments without assurances regarding the smelter's long-term operational viability. Bédard expressed concerns about the potential closure of the facility, asserting that the operations are safe for the local population and that protecting jobs is a priority for Glencore.

Critics, including local residents and environmental advocates, have raised concerns about Glencore's emissions and the provincial government's regulatory oversight. The class-action lawsuit reflects broader community dissatisfaction with how emissions from the Horne Smelter have been managed and the perceived failure of the government to enforce environmental standards effectively.

While Glencore has stated that it has taken steps to ensure the sustainability of its operations since the summer of 2025, the Quebec government has not publicly commented on the specifics of the negotiations or the reasons for the lack of agreement. The absence of detailed responses from provincial authorities leaves gaps in understanding the regulatory landscape surrounding the Horne Smelter.
