Canada Flight Cancellations and Delays: 56 Flights Cancelled, 391 Delayed Across London, Toronto, Montreal, Calgary, and More

Air Canada, WestJet, Air Transat, and Porter Airlines are among the carriers hit by widespread Canadian flight disruption.

Air travel across Canada has been thrown into disarray after 56 flights were cancelled and 391 delayed on Thursday, with disruption recorded at major airports including Toronto, Montreal, Calgary, Edmonton, Halifax and London, Ontario. Air Canada, WestJet, Air Transat, Porter Airlines and Jazz Aviation are among the carriers affected, leaving passengers facing longer waits and changes to their travel plans.​​​​​​​

Toronto Pearson International Airport bore the brunt of the disruption, recording 166 delayed flights and 26 cancellations, for a total of 192 affected services. As one of Canada's busiest hubs for both domestic and international travel, delays at Pearson often have a knock-on effect, with late-arriving aircraft and crews creating further schedule changes throughout the day. Passengers connecting through Toronto are being advised to allow extra time between flights and to monitor departure boards and airline notifications closely.​​​​​​​

Montréal–Trudeau International Airport was the second most affected, with 93 delays and 11 cancellations recorded, bringing its total to 104 disrupted flights. The disruption is likely to affect both domestic travellers and those using Montreal as a connection point for international journeys. Anyone with connecting flights booked separately is advised to check their full itinerary carefully in case of further changes.​​​​​​​

Several airlines were caught up in the disruption. Jazz Aviation, which operates many regional routes under the Air Canada Express brand, recorded the highest number of affected flights among individual carriers, with 77 delays and 24 cancellations. Air Canada itself reported 73 delays and 12 cancellations, while Porter Airlines logged 63 delays and 13 cancellations. WestJet also experienced delays across parts of its domestic network, with Air Transat and Air Canada Rouge flights affected as well. The impact varied by route, with some passengers facing only minor delays while others dealt with missed connections or outright cancellations.​​​​​​​

No single confirmed cause has been identified across all the affected flights. Disruption on this scale is typically the result of a combination of factors, including weather conditions, aircraft availability, crew scheduling, airport congestion and air traffic control restrictions, with the cause often differing from flight to flight. Passengers are encouraged to contact their airline directly to confirm the reason behind their specific delay or cancellation, as this can affect what assistance, rebooking options or compensation may be available.​​​​​​​

With flight schedules continuing to change throughout the day, travellers passing through Canadian airports are advised to check their flight status regularly before heading to the airport.
