A mix of wintry weather has struck Canada, prompting severe weather warnings in more than half of the provinces and two of the three territories. Air Canada, Porter, Jazz, and Endeavor Air are facing major disruptions, with 92 cancellations and 479 delays reported so far. Travelers flying through Toronto, Montreal, St. John’s, and other cities are dealing with significant delays as blizzard-like conditions, heavy snow, and bitter cold sweep across the country. On the East Coast, Newfoundland, Nova Scotia, and Prince Edward Island are experiencing severe weather, with up to 40 cm of snow expected in some areas. Coastal flooding, damaging winds, and blowing snow are making conditions even worse.

Further west, Alberta, British Columbia, and the Yukon are also under weather warnings for freezing rain, heavy snow, and extreme cold, with wind chills reaching as low as -50°C in some regions. As the severe winter weather continues, passengers should stay updated on flight status and prepare for ongoing disruptions.
