Canada Post is resuming operations after a month-long strike by more than 55,000 postal workers left letters and parcels in limbo.
The Canada Industrial Relations Board (CIRB) ordered postal workers back on the job after holding hearings over the weekend to determine whether the two sides were too far apart to reach a deal by the end of 2024.
The hearings followed a directive from Labour Minister Steven MacKinnon, who said Friday he was giving the two sides a “timeout” as negotiations appeared to have stalled.
However, the Canadian Union of Postal Workers (CUPW) is challenging the intervention into the strike. The union maintains that the directive undermines collective bargaining rights and has already filed a formal appeal. The CIRB is set to hear the union’s challenges in mid-January.
The government’s involvement has sparked debate, with legal challenges already underway against similar interventions in other recent high-profile labour disputes. Critics argue that the federal government’s approach risks setting a precedent that could weaken labour movements across the country.
Canada Post, meanwhile, is working to clear the significant backlog of letters and parcels accumulated during the strike. The Crown corporation has warned customers to expect delays, noting that disruptions may persist well into the new year as they stabilize operations.
For now, Canadians can expect mail and parcel delivery to resume, but the lingering effects of the strike and unresolved tensions between Canada Post management and CUPW suggest that further disruptions remain a possibility.
