Air Canada weather disruption causes new Calgary cancellations and 480 affected flights in Canada

Disruption overview

Air Canada is still working through a nationwide disruption after snow and freezing rain swept across Canada on 5 and 6 April 2026. By 8 April, the latest issues were centered on Calgary International Airport (YYC), where 5 flights were canceled and multiple other departures were delayed by more than 2 hours, while the wider disruption has already affected at least 480 flights across hubs including Toronto Pearson, Vancouver International, and Montréal–Trudeau. Because the problem was triggered by severe weather, compensation is usually unlikely, but passengers should still be offered rebooking or a refund, plus care and assistance during long waits.

Disruption details

Passengers flying with Air Canada are still seeing disruption across Canada after a late-season mix of snow and freezing rain swept across the country on 5 and 6 April 2026. On 8 April, the latest problems were centered on Calgary International Airport (YYC), where the airline confirmed 5 cancellations and several more departures were delayed by over 2 hours.

For passengers, this has meant longer waits, missed connections, and uncertainty even after the worst of the weather moved on. Calgary is a key hub for western Canada, so even a small number of cancellations there can quickly spread to domestic and cross-border connections linking Toronto Pearson, Vancouver International, and Montréal–Trudeau.

The wider disruption began during the Easter travel peak, when heavy precipitation and low visibility forced ground stops across parts of the network. Air Canada canceled more than 80 flights and delayed over 400 nationwide, meaning at least 480 flights have been affected so far.

Recovery is taking time because aircraft and crews are still out of position, some crew members have already reached their maximum working hours, and missed maintenance windows have made it harder for the airline to return to its regular schedule.

Easter travel also leaves very little spare capacity in the system. Flights at this time of year often run 85% to 95% full, which means there isn't much room to absorb disruption once schedules start to slip.

Disruption has been reported at several major hubs, including:

• Calgary International Airport (YYC), where 5 cancellations were confirmed on 8 April and several more flights were delayed by over 2 hours.

• Toronto Pearson International Airport (YYZ) and Vancouver International Airport (YVR), which each saw roughly 100 delayed departures on the worst days.

• Montréal–Trudeau International Airport (YUL), Ottawa Macdonald–Cartier International Airport (YOW), Halifax Stanfield International Airport (YHZ), Québec City Jean Lesage International Airport (YQB), and Winnipeg James Armstrong Richardson International Airport (YWG), which have all faced significant knock-on disruption since 5 April.

Air Canada hasn't given a firm end date for the disruption. Recovery from a weather event on this scale usually takes 48 to 72 hours after the last storm impact, so passengers should be prepared for rolling delays of 2 to 4 hours through 9 and 10 April.

If your trip has been affected, using the airline's app or website may be quicker than calling, as rebooking lines are still busy.

Because this disruption was caused by severe weather, compensation is usually unlikely. That said, if your flight was canceled, Air Canada should still rebook you on the next available flight or offer a refund if you decide not to travel.

If you're left waiting at the airport, you should also receive care and assistance, such as food and refreshments, and hotel accommodation plus transportation if the delay runs overnight.
