Workers at the Highland Valley Copper mine in British Columbia began a strike on Saturday after contract negotiations with Teck Resources Ltd. reached an impasse. Operations at the mine, one of Canada’s largest copper producers, are continuing but at a reduced capacity.

The strike was initiated following the expiration of a 72-hour notice served by United Steelworkers (USW) Local 7619. The union, which represents about 1,200 employees at the mine, has been negotiating a new collective agreement with Teck. According to the union’s strike notice, the workers are seeking higher wages and improved pension benefits. The USW also cited ongoing challenges related to staffing shortages and difficulties in attracting and retaining skilled workers at the site.

Teck acknowledged the impact of the strike on production will largely depend on how long the work stoppage continues. The company said it remains committed to reaching a new agreement through negotiations.

The USW did not immediately respond to requests for comment on the strike’s progress or next steps. The situation at Highland Valley Copper is closely watched given its significance in the mining sector and its role in the regional economy of British Columbia.
