Thousands of passengers across Canada faced a day of chaos on January 26, 2026, as a powerful winter storm and cascading operational disruptions triggered hundreds of flight cancellations and delays at major airports. Airlines including WestJet, Jazz, Republic, PAL and Porter Airlines were among those hardest hit, with a combined toll of roughly 560 cancellations and 170 delays affecting travel through Toronto, Montreal, Ottawa, Edmonton, Vancouver and a string of other cities.

Storm Battering Eastern Canada Triggers Aviation Meltdown

The latest wave of disruption is closely tied to the far-reaching January 2026 North American winter storm, which has swept from the United States into central and eastern Canada, bringing heavy snow, extreme cold and treacherous winds. As the system pushed into southern Ontario and Quebec on January 25 and 26, conditions quickly deteriorated at the country’s busiest hubs, including Toronto Pearson, Montreal Trudeau and Ottawa.

At Toronto Pearson, Canada’s largest airport, strong winds and intense snowfall reduced visibility and slowed down every aspect of airfield operations, from deicing to runway clearing. Airport authorities activated enhanced winter response plans as plows, sweepers and deicing trucks struggled to keep pace with rapidly accumulating snow and ice. Similar scenes played out in Montreal, Ottawa and across parts of Atlantic Canada, where wind chill values plunged well below minus 30 degrees Celsius.

Farther west, conditions were more variable but still disruptive. Airports in Edmonton and Vancouver reported knock-on effects from the battered eastern corridor as aircraft and crew rotations were thrown off schedule. Even where local weather remained manageable, carriers increasingly opted to preemptively cancel or consolidate flights rather than risk aircraft becoming stranded away from base or forcing crews beyond legal duty-time limits.

Passenger Impact: Stranded Families, Missed Connections and Overnight Stays

For travelers, the result was a sprawling patchwork of stranded passengers, missed connections and improvised overnight stays. At Toronto Pearson’s Terminal 1 and Terminal 3, long lines formed at airline service counters as passengers queued to be rebooked. Some travelers reported waiting several hours to speak with customer service agents after receiving abrupt cancellation alerts on their phones.

Families bound for winter sun destinations such as Cancun, Punta Cana and Florida resorts saw holiday plans upended as southbound departures were scrubbed with little notice. With many flights operating at or near full capacity even before the storm, rebooking onto later departures proved difficult, particularly for larger groups trying to travel together. Some resort-bound passengers were told that the earliest available replacement flights could be several days away.

Business travelers and international passengers connecting through Canadian hubs also faced significant disruption. A canceled or heavily delayed domestic leg often meant missed onward flights to Europe, the Caribbean or other North American cities. While airlines attempted to accommodate affected customers on alternative routings where possible, limited spare capacity and continuing operational uncertainty left many with few immediate options beyond hotel vouchers and standby lists.

WestJet, Jazz, Republic, PAL and Porter Grapple with Operational Fallout

Among the airlines bearing the brunt of the meltdown were WestJet, Jazz, Republic, PAL and Porter Airlines, each contending with a different mix of weather, resource and logistical challenges. Regional carrier Jazz, which operates many flights under capacity purchase agreements for larger brands, saw a high proportion of its short-haul schedule impacted, especially in and out of Toronto and Montreal. These routes are particularly sensitive to weather, with frequent takeoffs and landings, tight turnarounds and a heavy reliance on deicing services.

WestJet, with a broad domestic and transborder network, issued multiple travel advisories covering key cities in Ontario, Quebec and Atlantic Canada, acknowledging that winter storm conditions were heavily constraining its ability to operate a normal schedule. The airline offered flexible rebooking policies and fee waivers for affected passengers, but acknowledged that aircraft and crew imbalances would persist beyond the immediate weather window.

Porter Airlines, which flies from Toronto’s downtown Billy Bishop Airport as well as a growing number of jet routes from Pearson and Ottawa, was forced to cancel and delay numerous departures as strong winds and visibility restrictions complicated operations at smaller urban airports. Regional operators such as PAL, serving Atlantic provinces and remote communities, faced particularly difficult decisions, balancing safety and schedule integrity for passengers who may have limited alternative transport options.

Major Hubs from Toronto to Vancouver Struggle to Maintain Flow

Toronto, Montreal, Ottawa, Edmonton and Vancouver all experienced varying degrees of travel disruption, underscoring how quickly conditions at a few key nodes can ripple throughout a national network. At Toronto Pearson, one of North America’s most weather-sensitive hubs due to its volume and geography, runway throughput was sharply reduced by heavy snowfall and repeated deicing cycles. Even flights that ultimately operated often left late, compounding congestion at gates and in taxi lanes.

Montreal Trudeau similarly faced frigid temperatures and icy conditions that slowed ground handling and baggage operations. Prolonged exposure for ramp staff working in extreme cold required more frequent crew rotations and safety checks, adding to turnaround times. In Ottawa, a combination of blowing snow and intense cold brought delays to regional and national routes, particularly those reliant on smaller regional jets and turboprops that are more susceptible to performance limitations in adverse weather.

In Western Canada, Vancouver International Airport contended with the cascading impact of cancelled and delayed inbound flights from affected regions. While its coastal climate spared it from the most extreme cold and snowfall seen in central and eastern Canada, knock-on effects were inevitable as crews and aircraft failed to arrive on schedule. Edmonton International experienced a similar dynamic, with flights dependent on feed from Toronto, Montreal and other eastern hubs meeting severe disruption.

Weather Patterns, Crew Rules and Equipment Shortages Create a Perfect Storm

The scale of Monday’s aviation breakdown reflects not only the severity of the weather but also how complex and tightly tuned modern airline operations have become. Winter storms do not simply shut down a single airport; they ripple through an interconnected web of schedules, routing plans and regulatory requirements. Once significant numbers of flights are canceled in one region, aircraft and crew are left out of position for subsequent flights across the network.

Federal regulations strictly limit how long flight and cabin crews can be on duty, particularly in stressful weather conditions. When aircraft sit on the ground awaiting deicing, or when taxi times lengthen due to runway capacity restrictions, duty clocks continue to run. Flights that might technically be able to depart from a weather perspective are sometimes canceled instead because there is no legal crew available to operate them or because a crew would time out before reaching its destination.

Meanwhile, ground handling resources become overstretched. Deicing trucks and crews can serve only a finite number of aircraft per hour, and the colder and snowier it gets, the more often wings and tail surfaces need to be treated. With many Canadian hubs dealing simultaneously with heavy snow, ice pellets and brutal wind chills, the time required to prepare each aircraft for departure rose sharply. In such conditions, airlines often choose to prune their schedules aggressively, focusing on maintaining a core set of flights rather than trying and failing to operate a full timetable.

Airlines Offer Fee Waivers, Rebooking and Credits, but Frustration Mounts

Carriers moved quickly to publish flexible travel policies for affected customers, hoping to encourage voluntary changes and reduce congestion at airports. WestJet, for example, provided details on rebooking options and fee waivers for passengers traveling through cities in Ontario, Quebec and Atlantic Canada over the January 25 to 26 period. Similar measures were introduced earlier in the weekend for flights through Halifax, Moncton, Quebec City and several U.S. destinations affected by the same storm system.

These policies typically allow passengers to change their travel dates within a specified window without paying change fees, although fare differences can still apply. Some airlines also offered travel credits or, in the case of vacation packages, future credits for unused portions of trips, subject to hotel penalties and package rules. For many travelers, however, the primary challenge was not the cost but the scarcity of seats on alternative flights, particularly during the busy winter getaway season.

At crowded terminals, tempers occasionally flared as passengers encountered long waits, limited information and conflicting messages from mobile apps, call centers and airport staff. Some customers arriving at airports discovered that their flights had been canceled while they were en route, while others learned of last-minute schedule changes only at the gate. In interviews, travelers expressed a mix of understanding about the weather-driven safety concerns and frustration over what they saw as insufficient communication and contingency planning.

Consumer Rights Under Scrutiny as Disruptions Pile Up

The latest wave of cancellations has once again drawn attention to passenger rights under Canadian regulations, which outline compensation and assistance obligations for airlines during delays and cancellations. While weather-related disruptions are generally categorized as outside carrier control, thus limiting cash compensation requirements, airlines are still expected to provide timely updates and reasonable support, such as rebooking on the next available flight and offering food or accommodation in certain circumstances.

Advocacy groups have argued that recurring winter disruptions highlight gaps in both airline planning and regulatory enforcement, particularly when storms are forecast days in advance. They contend that while safety must remain paramount, carriers and airports can do more to streamline communication, strengthen staffing plans and invest in additional winter operations equipment so that service can resume more quickly once conditions improve.

Industry representatives counter that the magnitude of the current storm system, coupled with record-setting cold in some regions, has created truly exceptional conditions. They point out that many flights that were canceled early were done so deliberately, to give passengers as much notice as possible and to avoid chaotic last-minute scrubs when customers are already at the gate or on board. From their perspective, the emphasis on preemptive cancellations is part of a broader shift toward more predictable, if still disruptive, winter operational strategies.

Outlook: Continued Disruption as Airlines Work to Rebuild Schedules

With the storm still influencing weather patterns over parts of eastern Canada and the United States, airlines caution that effects on the flight network will persist beyond January 26. Even as snowplows clear runways and skies begin to brighten, carriers must reposition aircraft and crews, untangle missed maintenance windows and manage a backlog of passengers needing seats on already busy flights.

For travelers with imminent plans, experts recommend checking flight status frequently, signing up for airline text and email alerts, and using airline mobile apps to manage rebookings where possible. Those with flexible itineraries may wish to consider pushing travel plans out by a few days to avoid the most crowded re-accommodation periods. Passengers originating from or connecting through Toronto, Montreal, Ottawa, Edmonton and Vancouver should be prepared for residual delays and schedule changes as airlines and airports work through the aftermath.

The events of this stormy weekend and Monday’s mass cancellations will add to the growing body of evidence that Canada’s aviation system is increasingly vulnerable to extreme weather and climate volatility. For airlines, airports and regulators, the challenge will be to translate yet another winter of disruption into concrete changes that can help keep passengers moving, even when the snow, wind and cold return in force.
