Canada Post rejects union’s request for binding arbitration to end labour dispute
- On June 1, 2025, Canada Post declined a proposal from the union representing approximately 55,000 postal workers to resolve their ongoing labour dispute through binding arbitration.
- The union made the request to resolve months of stalled negotiations that have not produced a new collective agreement.
- Canada Post argues that binding arbitration would prolong instability, add complexity, and worsen its significant financial challenges.
- The company offered a 14 per cent cumulative wage increase over four years, a signing bonus up to $1,000, and an end to compulsory overtime.
- The rejection suggests ongoing labour unrest may continue, as the union banned overtime and is in legal strike position since May 23, 2025.

Canada Post rejects union’s offer of binding arbitration to end contract struggle
The union responded to Canada Post’s provocative call for the government to force a vote on its “final” contract offer, by proposing to surrender workers’ rights to strike and to determine, through collective bargaining, their terms of employment.
Canada Post strike update: Union’s binding arbitration request is rejected
During arbitration, employees cannot strike, and the employer cannot lock-out workers, CUPW added. If Canada Post’s final offers are rejected by employees, CUPW added the dispute could further divide the parties and harm Canada Post’s business and the public.
Canada Post submits that arbitration would be lengthy and complicated and would probably last more than a year.


The disagreement persists between the Union des travailleurs des travailleurs des postes (STTP) and the management of Canada Post.
