Thousands of air passengers were left in limbo across Canada on January 2, 2026, after severe winter weather triggered at least 598 flight delays and 98 cancellations at major hubs including Toronto, Vancouver, Montreal and Calgary.

Air Canada, WestJet, regional carrier Jazz and U.S. operator Republic Airways were among the airlines scrambling to manage the fallout as blizzards, snow squalls, high winds and dense fog disrupted schedules and snarled ground operations at airports from the Pacific Coast to Atlantic Canada.

Storm System Batters a Network Already Stretched by a Harsh Winter

The latest wave of disruptions struck as a powerful winter system swept across large parts of the country, compounding an already difficult holiday and early winter travel season.

Environment Canada advisories pointed to a volatile mix of heavy snow, freezing rain, high winds and extreme cold affecting multiple provinces, making safe takeoffs and landings increasingly difficult as the day progressed.

While Canadian airports routinely operate in subzero conditions, the severity and geographic spread of this week’s storm created a cascading effect.

Toronto Pearson, Vancouver International, Montreal Trudeau and Calgary International all reported significant operational constraints as visibility dropped, runways required repeated clearing and de-icing backlogs grew.

Smaller airports in Ottawa, Quebec City, Victoria and Nanaimo also reported clusters of delays and cancellations, magnifying pressure on the national network.

The disruption follows a string of major winter-weather events in December 2025 that had already stretched airline crews, aircraft rotations and airport infrastructure.

Industry analysts say the current storm illustrates how quickly a system-wide breakdown can reoccur when carriers are operating with little slack at peak travel times.

Where Disruptions Hit Hardest Across Canada

According to figures compiled from national flight-tracking data and airport reports, a total of 598 flights were delayed and 98 canceled at Canadian airports on January 2.

Toronto Pearson International emerged as the most severely affected hub, recording roughly 229 delays and 34 cancellations as the combination of snow, gusty crosswinds and low clouds slowed operations to a crawl.

Vancouver International, often a key trans-Pacific gateway, logged at least 82 delays and 23 cancellations as snowfall and persistent fog forced pilots and air-traffic controllers to space out arrivals and departures, sharply reducing the airport’s capacity.

Montreal Trudeau reported around 109 delays and 15 cancellations amid accumulating snow and blowing conditions, while Calgary International saw 112 delays and 7 cancellations as a fresh band of snow and freezing fog moved across southern Alberta.

Further knock-on effects were felt in Ottawa, Quebec City, Victoria and regional airports in British Columbia and Atlantic Canada, where smaller but still significant numbers of flights were either pushed back for hours or scrubbed entirely.

With aircraft and crews stuck out of position, even airports spared the worst of the weather began seeing schedule disruptions by late afternoon.

Air Canada, WestJet and Regional Partners Struggle to Rebuild Schedules

Flag carrier Air Canada and Calgary-based WestJet, which together operate the largest share of domestic and transborder routes, bore much of the brunt.

The two airlines rely heavily on Toronto, Montreal, Vancouver and Calgary as connecting hubs, meaning disruptions at a handful of airports quickly spilled across their networks.

Regional operator Jazz, which flies as Air Canada Express on many shorter routes in Eastern and Central Canada, faced acute challenges as small airports contended with fast-changing local conditions, from whiteout snow squalls in Ontario and Quebec to freezing drizzle on the Atlantic coast.

Republic, which operates feeder flights into Canadian hubs on behalf of U.S. carriers, also reported multiple delays as cross-border schedules were adjusted and U.S. connections rebooked.

Industry observers noted that while airlines have tightened winter protocols after several years of headline-grabbing meltdowns, the combination of severe weather and high seasonal demand still leaves little margin for error.

When storms arise across multiple regions at once, carriers must make rapid decisions on which routes to prioritize, which flights to consolidate and how to ensure crews remain within duty-time limits.

Passengers Face Overnight Stays, Long Lines and Sparse Information

For travelers caught in the disruption, the practical impact was hours-long waits, missed connections and an urgent scramble for hotel rooms.

Across Toronto, Vancouver, Montreal and Calgary, lines formed early at rebooking counters as passengers tried to secure new itineraries before inventory disappeared.

Many reported being placed on flights leaving a full day or more later than originally planned.

Families returning from holiday trips, business travelers bound for year-opening meetings and international visitors connecting onward to the United States, Europe and Asia were all affected.

With airport hotels quickly selling out, some travelers resorted to sleeping in terminal seating areas, huddled under jackets or using carry-on luggage as makeshift pillows.

Customer frustration grew as weather conditions shifted, with some passengers questioning why certain flights appeared to operate while others were canceled.

Airlines emphasized that decisions were rooted in safety considerations, available de-icing capacity, runway configurations and crew availability.

Yet in crowded terminals, those distinctions were often hard for passengers to see, especially when communication through text alerts and app notifications lagged behind real-time conditions.

Weather Extremes Stretch from Atlantic Canada to British Columbia

The flight disruptions reflected the reach of a sprawling winter pattern affecting nearly every region of the country in some way.

In Atlantic Canada, snow, wind and fog advisories were in effect across parts of New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland and Labrador, with some areas forecast to receive 10 to 15 centimeters of snow followed by rain and fierce gusts.

These conditions complicated operations at airports including Halifax Stanfield and Charlottetown and hit smaller coastal communities particularly hard.

Quebec, Ontario and Manitoba grappled with a combination of snowfall, blizzard conditions and extreme cold.

In pockets of Quebec and northern Ontario, visibility dropped to near zero at times as wind whipped fresh powder across runways and access roads, affecting flights at Montreal Trudeau, Quebec City Jean Lesage and smaller regional fields.

Parts of Manitoba experienced blizzard warnings and wind chills approaching minus 50 degrees Celsius, forcing crews to limit time working outdoors on aircraft and ground equipment.

In Saskatchewan and Alberta, forecasters pointed to dangerous cold in northern regions paired with dense fog and snowfall further south.

Calgary and Edmonton both reported recurring de-icing queues and temporary pauses in ground operations as visibility deteriorated and ramp conditions became unsafe.

In British Columbia, snowfall and dense fog across interior and coastal regions reduced visibility along key approach paths to Vancouver International and to secondary airports such as Nanaimo and Victoria.

Operational Responses and Passenger Rights Under the Microscope

Airport operators and airlines activated winter contingency plans early, bringing in additional snowplow convoys, deploying more de-icing trucks and adjusting runway use to align with prevailing winds.

At Toronto Pearson and Montreal Trudeau, air-traffic controllers were forced to slow arrival and departure rates to preserve safety margins, even as terminal crowds grew and departure boards filled with orange and red alerts.

Carriers encouraged travelers to use digital tools to rebook or request refunds, in part to ease pressure on airport staff.

Some airlines introduced flexible-change policies, waiving fees for customers willing to move their trips later in the week or shift to alternative routings.

However, with aircraft and available seats in short supply during the busy holiday-to-New-Year window, many passengers found that the main challenge was not fees but availability.

The latest disruption has also renewed attention to Canada’s Air Passenger Protection Regulations. Under those rules, airlines are generally not required to pay financial compensation for delays and cancellations caused by weather or other safety-related issues outside their control.

They must, however, provide a basic level of care, such as food vouchers and accommodation, if passengers are stranded for extended periods and rebooking within a reasonable timeframe proves impossible.

Consumer advocates are already calling for more transparency on when and how these obligations apply during major weather events.

What Travelers Should Do if Their Flight Is Affected

Travel planners recommend that anyone scheduled to fly through Toronto, Vancouver, Montreal, Calgary or other affected airports in the coming days closely monitor airline apps and airport status boards.

Given the fluid nature of winter systems, flights that appear to be operating on time in the morning can quickly face delays as conditions change, and vice versa.

Experts suggest that travelers whose flights are canceled first seek self-service options in airline apps or websites, which often show more available seats than agents at busy counters can immediately access.

For itineraries involving international connections or multiple carriers, phoning the airline or working through a travel agent can sometimes unlock alternative routes not visible in standard booking channels.

Passengers are also urged to keep receipts for meals, ground transportation and any overnight hotel stays incurred while stranded.

While weather-related events may fall outside formal compensation frameworks, some airlines choose to reimburse reasonable expenses on a case-by-case basis, especially for long delays or when rebooking stretches into multiple days.

FAQ

Q1. Why were so many flights delayed or canceled across Canada on January 2, 2026?
Airlines delayed and canceled flights because a powerful winter weather system brought a mix of heavy snow, high winds, fog and extreme cold to multiple regions at the same time, reducing visibility, slowing de-icing and runway clearing operations, and forcing air-traffic controllers to cut back the number of takeoffs and landings for safety.

Q2. Which airports were hit hardest by the disruptions?
The most significant impacts were reported at Toronto Pearson, Vancouver International, Montreal Trudeau and Calgary International, with additional delays and cancellations at airports in Ottawa, Quebec City, Victoria, Nanaimo and several regional centers.

Q3. Which airlines were most affected by the storm-related problems?
Air Canada and WestJet experienced the largest number of disruptions because of their extensive domestic and international networks, while regional partners such as Jazz and U.S.-based Republic, which feed traffic into Canadian hubs, also reported widespread schedule changes.

Q4. How long can passengers expect the ripple effects to last?
Even after the worst of the weather passes, it can take 24 to 72 hours for airlines to reposition aircraft and crews, clear backlogs and stabilize schedules, so travelers may experience lingering delays and occasional cancellations for several days.

Q5. Are passengers entitled to compensation for weather-related cancellations in Canada?
Under Canada’s Air Passenger Protection Regulations, airlines are generally not required to pay monetary compensation when delays or cancellations are caused by weather or other safety-related circumstances beyond their control, although they may still owe duty-of-care such as meals or accommodation in certain situations.

Q6. What immediate steps should I take if my flight is canceled?
Travel experts advise first checking your airline’s app or website for self-service rebooking options, then contacting the carrier by phone or speaking with an airport agent if digital channels do not show workable alternatives, and avoiding security re-entry until you have a confirmed new itinerary.

Q7. How can I reduce the risk of being stranded during severe winter weather?
Planning early-morning departures, avoiding tight connections, choosing non-stop routes where possible and building in extra time around key events or holidays can reduce exposure to cascading delays, though no itinerary is entirely immune during major storms.

Q8. Will travel insurance help in this type of disruption?
Many comprehensive travel insurance policies offer coverage for trip interruption, unexpected accommodation and additional transportation costs caused by severe weather, but travelers need to review their specific policy wording and exclusions, and keep detailed receipts for any claims.

Q9. What should I know about connecting flights through the United States or Europe?
If a Canadian departure is delayed or canceled, onward connections through U.S. or European hubs may be automatically rebooked or canceled by partner airlines; passengers should monitor all legs of their itinerary, not just the initial segment, and contact the operating carrier for each leg if changes appear.

Q10. Are airlines changing their long-term approach to winter operations after repeated storms?
Carriers and airport authorities have invested in more de-icing equipment, improved forecasting and tighter scheduling buffers in recent years, but recurrent large-scale disruptions suggest that, as extreme weather becomes more common, they may need to further expand contingency planning and communication tools to protect passengers during peak seasons.
