Tuesday, July 1, 2025
More than 450 new flights were delayed or cancelled across Toronto Pearson, Vancouver, Montreal, and Calgary due to severe weather systems that disrupted operations for major carriers including Air Canada, Japan Airlines, United, Air France, Air India, TAP Air Portugal, WestJet, Porter, Jazz, and others. The widespread travel turmoil unfolded as storms, strong winds, and low visibility battered key regions, throwing airline schedules into disarray and leaving thousands of passengers facing long waits, rebookings, and stranded connections across Canada’s busiest airports.
Toronto Pearson International Airport
Toronto Pearson saw the highest volume of disruptions nationwide, with 136 delays and 20 cancellations, totaling 156 impacted flights. Airlines operating out of Canada’s busiest hub struggled to maintain schedule integrity as rain and crosswinds made runway operations difficult. Porter Airlines cancelled ten flights and delayed another twelve. Air Canada, Jazz, and Air Canada Rouge faced dozens of delays, while international carriers such as Air France, TAP Air Portugal, and United Airlines also saw multiple long-haul departures held back. With so many aircraft grounded or rerouted, Pearson became a bottleneck for domestic and international travelers alike.
Vancouver International Airport
On the West Coast, Vancouver International reported 78 delays and 8 cancellations, bringing its total disruption count to 86 flights. The impact spread across carriers including Air Canada, WestJet, Pacific Coastal Airlines, and Porter. International airlines such as Japan Airlines, Korean Air, and Air India saw their schedules hit particularly hard, with some delays extending over four hours. Heavy cloud cover and persistent rain created poor visibility conditions, grounding multiple flights and leaving travelers scrambling for updates. Even transpacific departures to Asia and the U.S. West Coast were stalled due to congestion on runways and gate hold-ups.
Montreal-Trudeau International Airport
Montreal wasn’t spared either. Trudeau Airport recorded 81 flight delays and 5 cancellations, for a total of 86 disruptions. Delays primarily hit Air Canada, Jazz, Porter, and Air Transat, while international flights with Air France, TAP Air Portugal, and Royal Air Maroc also faced significant setbacks. Wet tarmac conditions and airspace congestion contributed to the travel snarls. Some carriers, including Swiss, Lufthansa, and Tunis Air, reported more than 50% of their scheduled flights delayed. Local and international travelers alike found themselves stuck at gates or waiting in long rebooking queues.
Calgary International Airport
In Alberta, Calgary International Airport experienced 62 delays and 6 cancellations, totaling 68 flight disruptions. The majority of these came from WestJet and its regional affiliate WestJet Encore, with 41 total delays between them. Porter Airlines, Flair, and Jazz also encountered operational trouble as weather systems swept across the prairies. Though fewer in number compared to Toronto or Vancouver, the disruptions in Calgary impacted critical east-west connections, forcing ripple effects into secondary airports and feeder routes throughout Western Canada.
Edmonton International Airport
Just north of Calgary, Edmonton International logged 19 delays and 4 cancellations, adding up to 23 impacted flights. Once again, WestJet and WestJet Encore led the disruption tally. Though weather conditions were slightly more stable than in Calgary, the airport still dealt with residual fallout from delays upstream in Toronto and Vancouver, creating a domino effect. Passengers flying regional routes or connecting via hubs saw their itineraries shuffled as the situation evolved throughout the day.
Ottawa Macdonald–Cartier International Airport
In the nation’s capital, Ottawa International Airport reported 19 delays and 6 cancellations, for a total of 25 travel disruptions. Porter Airlines took the hardest hit with 11 delayed flights and 3 cancellations. Jazz and Air Canada also saw schedule changes as storms along the eastern corridor created congestion in arrival patterns. Flights arriving from and departing to Toronto, Montreal, and Halifax were particularly impacted, with crews citing turbulent air and limited visibility as primary factors.
Halifax Stanfield International Airport
Atlantic Canada saw its share of troubles as well. Halifax International registered 20 delays and 6 cancellations, totaling 26 flight disruptions. Air Canada and Porter Airlines struggled with low visibility, while smaller carriers like Air Saint Pierre and Pascan Aviation faced 100% delay rates on scheduled routes. Even a few U.S.-bound flights operated by American Airlines and Republic Airways were held back. Although storms in the Maritimes weren’t as intense as elsewhere, the residual disruption from other hubs made on-time performance nearly impossible.
National Totals and Weather Fallout
Across all seven major airports, the combined total reached 470 flight disruptions, including 415 delays and 55 cancellations. The airports most affected were:
- Toronto Pearson: 156 disruptions
- Vancouver: 86 disruptions
- Montreal: 86 disruptions
- Calgary: 68 disruptions
- Halifax: 26 disruptions
- Ottawa: 25 disruptions
- Edmonton: 23 disruptions
This wave of delays and cancellations underscores how vulnerable even Canada’s most efficient airports are to severe weather. Air traffic control centers, baggage handlers, and airline dispatch teams worked overtime to reroute planes and rebook passengers, but long lines and frayed nerves dominated the terminals.
