3. Airport‑by‑airport impact

3.1 Toronto Pearson International Airport (YYZ)

• Root cause: Snow accumulation on runways exceeded 12 cm, triggering mandatory runway closures for de‑icing.
• Operational response:

1. Initiated “winter‑hold” procedures (all arrivals placed in a holding pattern until runway clearance).
2. De‑icing trucks operated 24 hr, achieving an average 15‑minute turnaround per aircraft.
3. Result: 320 cancellations, with the longest delay recorded at 6 hours for a flight AC 876 to Vancouver.

3.2 Montréal‑Trudeau International Airport (YUL)

• Root cause: Ice‑slicked taxiways forced ground‑crew to re‑route aircraft, reducing gate‑to‑runway efficiency.
• Key action: Deployment of four additional portable de‑icing units,cutting average delay from 90 minutes to 45 minutes.

3.3 Calgary International Airport (YYC)

• Root cause: Snow‑drift buildup on the east runway (13R/31L), combined with low‑visibility instrument landing system (ILS) restrictions.
• Mitigation: Use of “snow‑plow convoy” to clear drift pockets every 30 minutes; however, 180 flights still cancelled due to crew‑log limitations.

3.4 vancouver International Airport (YVR)

• Root cause: Heavy wet snow caused runway braking‑distance concerns.
• Solution: Activation of “minimum‑pushback” protocol,allowing only aircraft equipped with higher‑performance anti‑skid systems to depart.

4. Airline operational adjustments

1. Air Canada

• Reduced winter schedule by 10 % on high‑traffic routes (e.g., YYZ‑YVR, YUL‑YYC).
• Re‑routed 200 passengers on canceled flights to alternate airports (e.g., Ottawa (YOW) for Toronto connections).
• WestJet
• Issued a “Winter Weather Alert” on its mobile app, prompting passengers to re‑book within 24 hours without fee.
• Prioritized aircraft equipped with Engine Anti‑Ice (EAI) systems for critical routes.
• Flair Airlines
• Adopted a “stand‑by crew pool” strategy,allowing crew to be swapped at the last minute,reducing cancellation ripple effects by ~15 %.

5.Safety protocols and de‑icing best practices

• Standard de‑icing window: 30 minutes per aircraft for light snow; extended to 45 minutes for wet snow ≥ 20 mm/hour.
• Ground‑crew checklist:
• Verify pitot‑tube heating activation.
• Confirm wing‑tip anti‑ice fluid coverage (minimum 6 mm).
• Record fluid temperature to ensure optimal viscosity (‑5 °C to ‑15 °C range).
• Airport collaboration: NAV Canada shares real‑time runway friction data with airlines, enabling precise timing for “hot‑swap” de‑icing (switching to a freshly de‑iced aircraft within 10 minutes).

6.Passenger rights and compensation (Canadian regulations)

• Air Passenger Protection Regulations (APPR): Airlines must provide:

1. Rebooking on the next available flight (no extra charge).
2. Refund if the passenger opts not to travel.
3. Compensation of CAD 300‑600 for delays ≥ 6 hours when the cause is within the airline’s control (weather‑related disruptions are considered outside control, so compensation is not mandatory unless a service failure occurs).
4. Practical tip: Keep all e‑tickets,boarding passes,and interaction logs to streamline any future claim.

8.Case study: Toronto Pearson’s “Winter hold” execution (Dec 27, 2025)

• Timeline:
• 02:15 ET: Snow accumulation reaches 13 cm; runway 24L closed.
• 02:30 ET: air Traffic Control (ATC) initiates “Winter Hold” – all inbound flights placed in a 30‑minute holding pattern.
• 03:00 ET: First de‑icing team completes 12 aircraft; turnaround time reduced to 12 minutes per plane due to additional fluid trucks.
• 04:45 ET: Runway 24L reopened after 1 cm snow removal and friction test (G‑rating = 3).
• Outcome: Delay reduction of 22 % after the first hour; though, 320 flights still canceled due to crew duty‑time limits and passenger‑load constraints.

9. Frequently asked questions (FAQ)

Question	Answer
Will my luggage be transferred automatically after a cancellation?	Most airlines automatically re‑route checked baggage to the next available flight. Always confirm with the check‑in desk or mobile app.
Can I claim a hotel reimbursement for a forced overnight stay?	Under the APPR, airlines are not obligated to cover accommodation for weather‑related cancellations. some carriers (e.g., WestJet) offer voluntary vouchers as goodwill.
How does a “snow‑drift” differ from regular snowfall in terms of flight impact?	Snow drifts accumulate around runway edges, reducing usable runway length and increasing friction. They require special snow‑plow convoys and frequently enough trigger runway closures faster than uniform snowfall.
Is it safer to travel on smaller regional aircraft during a winter storm?	Regional jets often have more robust anti‑ice systems and can operate on shorter, cleared runways.Though, they are also more susceptible to turbulence and icing at lower altitudes.
