BC Port Seeks Injunction Against Striking Steelworkers Union
Trigon Pacific Terminals sued United Steelworkers for illegal interference at Port of Prince Rupert.
Why it matters: Labor disputes involving separate unions at a major Canadian port affect critical supply chains and present legal challenges relevant to corporate counsels and legal operations overseeing risk and compliance in logistics and infrastructure sectors.
- Strike began October 2, 2026, involving about 110 workers from ILWU Local 523, a different union from United Steelworkers.
- Canada Industrial Relations Board ordered Trigon Pacific Terminals on October 27, 2026, to stop using contractors for union jobs to comply with labor laws.
- Trigon filed for an injunction on November 11, 2026, alleging illegal interference by striking United Steelworkers at the port.
- The strike has disrupted coal and liquefied natural gas shipments, reducing train movements at the port by nearly 50%.
On November 11, 2026, Trigon Pacific Terminals filed a legal injunction against striking workers represented by the United Steelworkers, alleging illegal interference with port operations at the Port of Prince Rupert in British Columbia.
The ongoing strike began October 2, 2026, involving approximately 110 employees from the International Longshore and Warehouse Union (ILWU) Local 523. Notably, the ILWU and United Steelworkers represent different worker groups, reflecting complex union dynamics in the dispute.
On October 27, 2026, the Canada Industrial Relations Board issued an order directing Trigon Pacific Terminals to halt the use of contractors for tasks typically performed by the unionized workforce, aiming to adhere to labor regulations during the strike.
Trigon alleges that members of the United Steelworkers engaged in conduct amounting to illegal interference with port operations, although court documents have not detailed specific actions. The injunction seeks to restrain such activities given their impact on critical infrastructure and trade flow.
The Port of Prince Rupert is a vital logistics hub, handling key commodities including coal and liquefied natural gas (LNG). The strike has led to nearly a 50% decrease in train movements for coal shipments, intensifying pressure on regional supply chains.
ILWU Local 523 has publicly underscored the importance of protecting workers' rights amid collective bargaining, cautioning against disregarding labor concerns during ongoing negotiations.
This multifaceted labor dispute underscores legal complexities faced by corporations and legal teams managing union relations, compliance with labor laws, and operational risks within strategic trade infrastructure.
By the numbers:
- 110 workers — involved in strike at Port of Prince Rupert from ILWU Local 523
- October 2, 2026 — strike commencement date
- 50% — reported drop in train movements for coal shipments during strike period
Yes, but: The injunction allegations focus on illegal interference without public details on specific conduct, and union officials emphasize labor rights, highlighting a legal tension between operational control and collective bargaining protections.
What's next: Pending court review of Trigon’s injunction request will shape legal precedent on permissible strike conduct at critical Canadian ports amid labor disputes.
