WestJet cancelled a total of 276 flights across Canada by 3 p.m. Mountain Time on August 1, 2026, as part of an organized wind-down in anticipation of a possible flight attendant strike. Flight cancellations began on the evening of July 31, with 80 flights cancelled, followed by 32 early morning, 86 mid-morning, and 78 mid-afternoon cancellations on August 1.
These cancellations respond to a 72-hour strike notice issued by the Canadian Union of Public Employees (CUPE), representing WestJet flight attendants, with the earliest possible strike or lockout start time set for 12:01 a.m. MT (2:01 a.m. ET) on August 2,
2026. Negotiations between WestJet and CUPE have not yielded a tentative agreement to avert the strike.
Routes Most Affected and Flight Operations
The route from Calgary International Airport (YYC) to Vancouver International Airport (YVR) experienced the highest cancellations, with seven flights cancelled. Other routes with three cancellations each include Calgary–Toronto, Vancouver–Calgary, Edmonton–Calgary, Calgary–Victoria, and Toronto–Calgary. Additionally, the Cancun–Toronto, Toronto–Vancouver, Toronto–Edmonton, and Calgary–Kelowna routes each recorded two cancellations.
WestJet’s mainline network is affected by these disruptions, while WestJet Encore Q400 flights and codeshare flights operated by partners remain unaffected. Sunwing Vacations, part of the WestJet Group, reported that most of its flights continue operating as scheduled amid
the cancellations.
Labour Negotiations and Federal Mediation
WestJet offered a “transformative, industry-leading” labour agreement to CUPE, including double-digit wage increases, additional compensation before and after flights, and scheduling improvements aimed at enhancing cabin crew flexibility and quality of life. The airline stated the proposal would have set a new benchmark for crew compensation and was structured to support long-term sustainability.
CUPE rejected the offer, maintaining their stance as negotiations with federal mediators have been ongoing since May 2026. Minister Patty Hajdu of the federal government emphasized the importance of reaching an agreement at the bargaining table, stating that both parties can and should reach a
deal. Minister Hajdu has indicated possible government intervention under Section 107 of the Canada Labour Code to maintain industrial peace if a strike occurs.
Official Statements on Flight Cancellations and Labour Dispute
WestJet explained that cancellations were initiated “to ensure the integrity of WestJet’s network, and to minimize the risk of stranding guests and aircraft.” The airline added that this approach allows it to maintain complete control over operations and communication with guests and crew. They reaffirmed commitment to reaching a negotiated agreement and expressed belief that a deal is within reach.
CUPE urged the federal government not to interfere, calling for respect of the collective bargaining process.
Minister Patty Hajdu remarked, “Both parties are working hard to renew their collective agreement. Our government has always maintained that the best deals are reached at the bargaining table. With federal mediators supporting negotiations since May, the parties can and should reach a deal. Canadians are counting on it.”
Passenger Impact and Travel Updates
Passengers affected by cancellations have been notified individually. Sunwing Vacations advised that notifications will be sent only to those whose flights are cancelled and urged customers to monitor their email for options. Travellers are directed to check WestJet’s Travel Advisory page for ongoing guest and travel information.
WestJet has encouraged passengers
to verify flight status before travelling to avoid unexpected disruptions. The cancellations are part of a controlled network reduction aimed at minimizing operational risks as the strike deadline of August 2, 2026, approaches.
Context of Government Intervention and Labour Relations
The federal government has the authority under Section 107 of the Canada Labour Code to intervene in labour disputes to maintain industrial peace. This measure was previously used in summer 2025 during an Air Canada flight attendant strike, where binding arbitration was imposed after contract negotiations broke down.
WestJet’s labour proposal included hourly pay for all work performed and compensation exceeding benchmarks in peer Canadian airline collective
agreements. The current stalemate continues despite these measures, with potential government intervention pending if the strike materializes.
