Air Canada suspended its plan to resume flights after a strike by cabin crew continued despite a government order requiring workers to return to duty and enter binding arbitration.
The airline had already canceled hundreds of flights and shut down operations in response to the walkout by about 10,000 flight attendants. The labor dispute quickly became a major travel disruption because Air Canada carries around 130,000 passengers a day and flies to 180 cities worldwide. In other words, this was not a contained corporate dispute. It was a nationwide transportation problem.
The immediate trigger was the workers’ decision to strike after rejecting an updated contract proposal. Hours later, Canada’s labor policy minister, Patty Hajdu, invoked a legal provision under section 107 of the Canada Labour Code to end the strike and force both sides into arbitration. The Canada Industrial Relations Board then ordered Air Canada and its flight attendants back to work by 14:00 EDT on August 17, 2025.
Even so, the union said the strike would continue. CUPE’s Air Canada unit told passengers not to go to the airport if they held tickets on Air Canada or its lower-cost Rouge subsidiary. That instruction made clear the dispute had not been resolved just because the government had intervened. The workers were still resisting the return-to-work order, and the airline could not simply restart operations as planned.
The issue at the center of the conflict was compensation for ground work. The union was seeking wage increases and relief for unpaid tasks, including duties performed during boarding. Air Canada said it had offered terms under which a senior flight attendant would average CAN$87,000 by 2027, but CUPE said the proposals were below inflation and below market value. Those competing claims show the distance between management’s and labor’s view of what fair compensation looks like.
The federal intervention also raised questions about the role of the state in a private-sector labor dispute. CUPE criticized the government for effectively rewarding Air Canada’s refusal to negotiate fairly. The union also pointed to the chair of the Canada Industrial Relations Board, Maryse Tremblay, whose past work as legal counsel for Air Canada became part of the dispute over legitimacy and fairness.
For travelers, the practical effect was confusion and delay. A flight schedule cannot be restored cleanly when the union and the airline are still fighting over whether the return-to-work order should be obeyed. The result was another day of uncertainty for passengers trying to move through one of Canada’s busiest carriers.
The Business Council of Canada had warned before the strike that a work stoppage at Air Canada would worsen economic pressures already being felt from U.S. tariffs. That forecast now looks more relevant because the shutdown hit an airline with a huge daily passenger load and broad international reach.
The article should not speculate on the final settlement because the packet does not provide one. What it does show is that the conflict escalated from a contract dispute to a labor showdown involving the airline, the union, the government and the regulator. Air Canada suspended its resumption plan because the strike still had force.
For now, the verified facts are stark: the airline shut down, the union kept striking, the government ordered a return to work, and flights remained suspended while the dispute played out.
