The Highland Valley strike has reduced operating capacity at Teck Resources’ copper operation in British Columbia. Teck said on October 24, 2026, that United Steelworkers Local 7619 had begun strike action, but the operation was continuing to run. The company said the overall production impact would depend on how long the labour action lasts.
Key Takeaways
- Highland Valley Copper remained operational at reduced capacity as of October 24.
- Teck did not quantify lost production or announce revised production guidance.
- Contingency plans prioritize safety and environmental management during the strike.

Highland Valley strike leaves production impact uncertain
Teck’s October 24 operational update described a partial disruption rather than a complete shutdown. The company did not disclose the level of capacity being maintained, an estimate of lost copper output or an expected end date for the strike.
That distinction limits what can be concluded about the production effect: reduced capacity is confirmed, but the scale of the eventual shortfall remains unknown. Teck identified the duration of the labour action as the determining factor.
The company also flagged potential effects on previously issued guidance in its forward-looking disclosures. Those cautions are not an announcement that guidance has been changed.

Contingency plans and collective bargaining
Teck said contingency arrangements were in place to maintain safety and environmental management during the disruption. Its ability to continue operating and implement those plans remains subject to uncertainty.
The company said it was committed to a collective agreement that is fair and reasonable for employees while supporting the operation’s ongoing viability. The announcement did not detail bargaining proposals or provide a timetable for reaching an agreement.
Conclusion
The immediate issue is how long reduced-capacity operations continue. A quantified production impact or a collective agreement would clarify the consequences of the Highland Valley strike; neither was announced in the October 24 update.
