Flights across Canada are facing major disruption as Toronto, Montreal, Ottawa, Vancouver and other cities experience widespread schedule interruptions, with 607 flight delays and 216 cancellations affecting Jazz, Air Canada, Porter Airlines, WestJet Encore and other carriers. The disruption has impacted passengers around Canada as severe thunderstorms, heavy rainfall, strong wind gusts and hail risks created challenging operating conditions at major airports. Toronto recorded some of the highest impacts, while Montreal, Ottawa, Vancouver and others also reported significant delays and cancellations. Additionally, weather alerts issued for Toronto and Montreal contributed to operational difficulties, forcing airlines to adjust schedules and manage passenger movements. Therefore, travellers across Canada are facing longer waiting times, cancelled flights and possible connection disruptions as airlines including Jazz, Air Canada, Porter Airlines, WestJet Encore and others work to restore normal operations.

Why are Canadian airports experiencing major travel disruptions today?

Environment Canada issued severe thunderstorm alerts for parts of Ontario and Quebec, warning of hazardous weather conditions including torrential rainfall, strong wind gusts and hail, which can affect airport operations, aircraft movements and ground handling activities. Toronto was placed under a severe thunderstorm watch, with possible rainfall exceeding 50 millimetres, wind gusts between 90 and 110 km/h, and hail ranging from quarter-size to ping-pong ball size. Montreal also remained under a yellow warning for severe thunderstorms, increasing concerns over weather-related disruptions.

Environment Canada warned that the storm system could bring damaging winds capable of affecting trees, fences and structures, with possible local power outages. Such conditions can create further challenges for airport infrastructure and passenger movement. Montreal has also faced significant disruption, with Montréal–Trudeau International Airport recording 93 delays and 57 cancellations. A yellow severe thunderstorm warning in Montreal has contributed to concerns over changing weather conditions, with airlines and airports managing possible impacts from heavy rainfall, strong winds and reduced operational efficiency.

Which Canadian airports are most affected by delays and cancellations?

The disruption has spread across several major Canadian airports, affecting both eastern and western aviation hubs.

Toronto has been among the hardest-hit locations, with Toronto Pearson International Airport recording 250 delays and 84 cancellations, while Toronto City Centre Airport reported 41 delays and 33 cancellations. The severe thunderstorm alert issued for Toronto has created additional pressure on air operations, as high wind gusts and intense rainfall can affect take-off and landing schedules.

Vancouver International Airport recorded 99 delays and 6 cancellations, showing that western Canada also experienced significant schedule interruptions. Calgary International Airport reported 52 delays and 9 cancellations, while Ottawa Macdonald-Cartier International Airport recorded 44 delays and 24 cancellations.

• We contacted the affected airports seeking official comments and updates on the disruptions; however, we received only automated responses.

Which airlines are facing the biggest impact from Canada’s travel disruptions?

Several major Canadian airlines and regional carriers have been affected by the disruption. Regional operator Jazz, which operates commuter services for Air Canada, recorded the highest number of cancellations among listed airlines, with 73 cancellations and 89 delays.

Air Canada reported 30 cancellations and 118 delays, reflecting the impact on one of Canada’s largest aviation networks. Porter Airlines recorded 19 cancellations and 97 delays, while WestJet Encore reported 8 cancellations and 14 delays.

Airlines operating regional and connecting services have faced additional pressure because delays at major hubs can create wider impacts across domestic routes.

What should affected passengers do now?

Travellers affected by delays or cancellations should take several steps to manage disruptions:

• Check the latest flight status with their airline before travelling to the airport.
• Allow additional time for airport arrival due to possible congestion.
• Monitor weather updates and airline notifications regularly.
• Contact airlines immediately if flights are cancelled or connections are missed.
• Keep flexible travel plans where possible during severe weather conditions.
• Follow airport safety instructions during thunderstorm activity.

Passengers should avoid relying only on original departure times, as severe thunderstorms can cause sudden changes to flight schedules.

Severe weather adds pressure to Canada’s aviation recovery

Canada’s travel disruption has been intensified by severe thunderstorm warnings affecting Toronto and Montreal, two of the country’s most important aviation centres. With 607 delays and 216 cancellations recorded across the listed airports, passengers face continued uncertainty as airlines manage weather-related operational challenges. The combination of torrential rainfall, powerful wind gusts, hail risks and possible power interruptions has created additional pressure on airports already experiencing widespread delays. Travellers are advised to remain alert, check updates frequently and prepare for changing flight schedules until weather conditions improve.
