Another Canadian Industry Down: Glencore Could Close Horne Smelter

Another Canadian industry at risk.

Mining giant Glencore is reportedly considering shutting down the Horne Smelter and the Canadian Copper Refinery in Quebec — Canada’s largest copper-metal operation.

Upgrades would cost over $200 million, and new environmental rules make it nearly impossible to stay competitive.

If this closure happens, it won’t just hit jobs — it may strike at the heart of Canada’s resource economy.

From furniture to rail, and now copper — how much more can Canada afford to lose?
