Storms across Canada disrupt Air Canada and WestJet flights with 88 cancellations and 518 delays

Disruption overview

Severe storms on 1 June 2026 disrupted air travel across Canada, triggering 88 cancellations and 518 delays for passengers flying with Air Canada, WestJet, WestJet Encore, Jazz, and several regional carriers. The storms first hit Alberta with gusts up to 100 km/h and heavy rain, before the knock-on effect spread nationwide. Edmonton International Airport saw the highest cancellation total, while Toronto Pearson International Airport and Montréal-Trudeau International Airport recorded the largest delay counts as aircraft and crews fell out of position across the network. Because the disruption was caused by severe weather outside airline control, compensation is usually unlikely, but stranded passengers should still receive rebooking or refunds, plus food, accommodation, and other care where needed.

Disruption details

Severe storms sweeping across Canada on 1 June 2026 disrupted flights at Edmonton International Airport, Calgary International Airport, Toronto Pearson International Airport, Montréal-Trudeau International Airport, and Vancouver International Airport. Airlines including Air Canada, WestJet, WestJet Encore, Jazz, and several regional carriers were caught in the knock-on effect, with 606 flight movements affected, including 88 cancellations and 518 delays. For passengers, this meant missed connections, longer waits, and a stressful day of uncertainty before many trips had even begun.

The worst weather hit Alberta first. Environment Canada issued rain and wind warnings for large parts of the province, with gusts reaching 100 km/h and heavy rain causing water to pool on roads and runways. As conditions worsened, airlines had to ground or hold departures, and once aircraft and crews fell out of position in Edmonton and Calgary, the disruption spread quickly through the wider Canadian network.

The hardest-hit airports were:

• Edmonton International Airport (YEG) recorded 33 cancellations and 35 delays.

• Calgary International Airport (YYC) logged 9 cancellations and 86 delays.

• Toronto Pearson International Airport (YYZ) saw 11 cancellations and 130 delays.

• Montréal-Trudeau International Airport (YUL) registered 14 cancellations and 133 delays.

• Vancouver International Airport (YVR) reported 11 cancellations and 101 delays.

Regional airports Kelowna International Airport (YLW) and Québec/Jean Lesage International Airport (YQB) also saw disruption. Together, the numbers showed how quickly bad weather in Alberta turned into a national problem, with Edmonton carrying the heaviest cancellation load and Toronto Pearson plus Montréal-Trudeau absorbing the largest delay totals.

The airlines with the biggest operational impact were:

• WestJet Encore led cancellations with 16 canceled flights and 22 delays.

• Air Canada recorded 14 cancellations and 95 delays.

• Jazz reported 14 cancellations and 86 delays.

• WestJet posted 10 cancellations and 83 delays.

Smaller carriers, including PAL Airlines, Pacific Coastal Airlines, Air Canada Rouge, and Air Inuit, were also drawn into the disruption as aircraft and crews were displaced throughout the day. That spread the pressure well beyond one or two airlines and made recovery harder across the network.

For many travelers, the problem wasn't only the weather at their own airport. A late aircraft in Edmonton or Calgary could quickly turn into a delayed departure in Toronto, Montreal, or Vancouver. That left passengers dealing with long lines, difficult rebooking choices, and a higher risk of missed onward connections.

Passengers were advised to keep checking their flight status, contact their airline early about rebooking, and consider alternative routings once conditions improved. The disruption was still unfolding on 1 June 2026, showing how quickly one province's storm can unsettle Canada's interconnected network during the busy summer period.

Because this disruption was caused by severe weather outside the airline's control, compensation is usually unlikely. Even so, if your flight was canceled or significantly delayed, your airline should still help with rerouting or a refund, and provide food, refreshments, and accommodation if you're stranded overnight.

Although compensation is unlikely here, that doesn't mean you're without support. If your journey was affected, AirHelp's free flight checker is a simple way to understand what rights and assistance may apply to your trip.
