Strike at Highland Valley Copper halts operations, raises questions about Canada copper supply and clean energy plans
More than 1,200 unionized workers at Teck Resources’ Highland Valley Copper mine began strike action on October 24, 2026, forcing the mine to operate at reduced capacity. The stoppage threatens near-term copper output from Canada’s largest open pit copper operation, with implications for regional employment, Teck’s near-term production guidance, and supply for industries tied to the energy transition.
