Strike Notice at Highland Valley Copper
USW Local 7619 served strike notice at HVC Operations, entitling the union to begin strike action on October 24, 2026, at 8:00 a.m. PT at the earliest.
-
No Collective Agreement in Place
The HVC collective agreement reached the end of its term on September 30, 2026; Teck says it is committed to reaching a fair and reasonable agreement.
-
Production Impact Not Quantified
Teck states operations continue and contingency plans are in place to maintain safety and environmental management, but the filing gives no estimate of any production or financial impact.
-
Timing Relative to Merger Mechanics
The notice comes after Teck's September 1, 2026 disclosure of final timing mechanics for the Anglo American merger, adding labour risk during the combination process.
Analysis · TECK · Energy & Transportation
A strike at Highland Valley Copper would cut into Teck's copper output just as record copper prices are driving results — Q2 2026 adjusted EBITDA was $2.2 billion, up 204% year-over-year. With the collective agreement already expired September 30, 2026, there is no contract in place, and the union can walk out as early as October 24, 2026. Teck says operations continue and contingency plans are set, but the filing gives no estimate of production impact, so the size of the hit is unknown. This lands three weeks before the Anglo American merger combination mechanics play out, adding operational noise to an already complex transaction timeline.
