Air Canada says it has suspended plans to resume limited operations after the union representing the airline’s flight attendants said Sunday it will defy a federal back-to-work order for binding arbitration to end the work stoppage.”Approximately 240 flights scheduled to operate beginning this afternoon have now been cancelled,” the airline said in a statement.Air Canada said it will instead resume flights as of Monday evening, but with more than 10,000 flight attendants remaining on strike, it is unclear how Air Canada plans to operate these flights.CBC News has reached out to the airline for clarification.Employees and union members protest outside Air Canada headquarters in Montreal Sunday after the federal government intervened in the labour dispute between the airline and the union representing its flight attendants.

But just hours later, the Canadian Union of Public Employees (CUPE) said in a statement that members would remain on strike and invited Air Canada back to the table to “negotiate a fair deal.””We will be challenging this blatantly unconstitutional order that violates the Charter rights of 10,000 flight attendants, 70 per cent of whom are women, and 100 per cent of whom are forced to do hours of unpaid work by their employer every time they come to work,” it said in a statement.

The carrier also said it will offer to rebook customers on other carriers, “although capacity is currently limited due to the peak summer travel season.”WATCH | Federal government steps in to resolve Air Canada labour dispute: Binding arbitration ordered to resolve Air Canada labour dispute: Minister HajduThe federal government is stepping in to resolve a labour dispute between Air Canada and the union representing flight attendants, Jobs Minister Patty Hajdu revealed on Saturday. Hajdu told journalists she is ordering binding arbitration and operations to resume.Air Canada had said earlier in the day it had been directed by the Canada Industrial Relations Board (CIRB) to resume operations and have flight attendants return to their duties by 2 p.m. ET.It said the CIRB had ordered the terms of the collective agreement between the union and the airline that expired on March 31 be extended until a new agreement is reached.Air Canada relies on government help: labour expertSteven Tufts, an associate professor and labour geographer at York University, says Air Canada has become dependent on the federal government to solve its labour-relations issues.He mentioned last year’s dispute between the airline and the pilots’ union; Air Canada asked for the government to be ready to step in before the two sides reached a tentative agreement in September 2024.”[Air Canada] tried to get the government to intervene with pilots last year,” Tufts told CBC News Network.”Air Canada has to learn not to call mommy and daddy every time they reach an impasse at the bargaining table.
