87 Canada Flights Canceled in Winter Storm — Toronto Hit Hardest

A late-winter storm is hammering Canada's busiest travel corridors today, forcing Air Canada, WestJet, Porter Airlines, Jazz, and other carriers to cancel 87 flights and delay more than 394 across Vancouver, Calgary, Toronto, Montreal, and Ottawa. The system is pushing heavy snow and gusty winds into Ontario and Quebec at a peak travel period, with Environment Canada issuing active snowfall warnings for southern Ontario — up to 15 cm of accumulation — that are slowing both airport ground operations and highway access to Toronto Pearson and Montréal-Trudeau, the country's two busiest hubs, according to FlightAware data.

Cascading delays are spreading well beyond the storm zone, disrupting connections for passengers transiting through Canadian hubs to international destinations.

The Storm System: What Environment Canada Is Warning

Environment Canada's active snowfall warning for southern Ontario is the immediate driver of today's worst disruptions. The warning covers the Greater Toronto Area and surrounding communities including Pickering, Oshawa, and Newmarket, where icy surfaces and up to 15 cm of snow are reducing visibility and slowing ground operations simultaneously.

The storm is tracking into Quebec next, raising the probability of further deterioration at Montréal-Trudeau as the day progresses. Both major Ontario and Quebec hubs are expected to remain under pressure through the evening banking hours.

Toronto Pearson Is Canada's Hardest-Hit Airport Today

Toronto Pearson International Airport (YYZ) is absorbing the brunt of the disruption with 40 cancellations and 186 delays — figures that dwarf every other Canadian airport today.

Heavy snow accumulation on runways and taxiways, combined with reduced visibility, has created a backlog concentrated in afternoon and evening departures. Passengers with flights later today at YYZ should assume delays and confirm status before leaving for the terminal.

Montreal-Trudeau (YUL) has recorded 10 cancellations and 56 delays as the storm edge reaches Quebec. Vancouver International (YVR), Calgary International (YYC), and Ottawa Macdonald-Cartier (YOW) are also logging disruptions at lower but still significant levels.

Airport-by-Airport Breakdown

Airport	Cancellations	Delays
Toronto Pearson (YYZ)	40	186
Montreal-Trudeau (YUL)	10	56
Vancouver International (YVR)	8	36
Calgary International (YYC)	Multiple	Elevated
Ottawa Macdonald-Cartier (YOW)	Multiple	Elevated

Airlines Taking the Biggest Hit

Jazz Aviation — Air Canada's regional subsidiary operating shorter domestic and connecting routes — is leading all carriers with 38 cancellations and 79 delays. Regional operations are almost always the first sector to absorb cuts during weather events, as smaller aircraft are more vulnerable and routes carry less rebooking flexibility.

Air Canada's mainline operations have recorded 22 cancellations and 267 delays, indicating the scale of network ripple effects beyond the direct storm zone. WestJet and Porter Airlines have each reported 8 cancellations, with 98 and 88 delays respectively. Porter's disruption is particularly concentrated at Billy Bishop Toronto City Airport, which sits closer to the storm's center of impact.

Airline	Cancellations	Delays
Jazz (Air Canada regional)	38	79
Air Canada	22	267
WestJet Encore	7	55
WestJet	8	98
Porter Airlines	8	88
Air Canada Rouge	5	54

What Affected Passengers Should Do Right Now

Check status before heading to the airport. Toronto Pearson and Montréal-Trudeau situations are changing hour by hour. Use your airline's app or the airport's official website — not third-party trackers — for the most current gate and departure information.

Rebook early using online tools. Air Canada, WestJet, and Porter are all offering weather waiver rebooking for affected itineraries. Using the airline's app or website to rebook is typically faster than waiting at the airport customer service desk during peak disruption.

Ask about meal vouchers and accommodation. For delays extending beyond 3 hours or cancellations on mainline routes, airlines may offer meal vouchers or hotel accommodation. Inquire at the counter or through the airline's customer service line directly — these offers are not always proactively communicated.

Sign up for flight alerts. All major Canadian carriers allow passengers to opt in to real-time SMS or email alerts on flight status changes. If you are not yet enrolled, do it now — notification of a cancellation before you leave home saves hours.

Pack airport essentials for extended waits. With the storm system expected to affect afternoon and evening banking at YYZ and YUL, passengers should carry chargers, snacks, medications, and any overnight essentials in carry-on luggage in case the disruption extends into tomorrow.

What This Means for the Rest of the Day

The storm system is still developing and tracking east toward Quebec, signaling that Montreal-Trudeau is likely to see deteriorating conditions before the evening ends. Toronto Pearson's backlog, built through the afternoon, typically takes 12 to 24 hours to clear even after weather improves — meaning some tonight's displaced passengers will not be rebooked until March 15 at the earliest.

Travelers with non-urgent plans are advised to delay departure for at least 24 hours if flexibility exists. Those who must travel should confirm their specific flight status and terminal access route before leaving home, as highway conditions in the GTA and surrounding regions are also being degraded by the same system.
