Recently, Canada has been hit by an unusually severe cold wave, with temperatures plummeting to as low as minus 30 degrees Celsius or lower in many regions, causing significant disruptions to transportation systems. Due to extreme cold and blizzard conditions, major aviation hubs—including Toronto Pearson International Airport, Vancouver International Airport, and Montreal-Trudeau International Airport—have experienced widespread flight delays and cancellations. According to Canadian aviation authorities, over 500 flights nationwide were affected in early January alone, disrupting travel plans for tens of thousands of passengers.Meteorologists attribute this cold snap to Arctic air masses moving southward, which combined with moisture from the Pacific Ocean to produce heavy snowfall and strong winds. In some areas, wind chill values have dropped below minus 40 degrees Celsius. Such extreme weather not only challenges air travel but also severely impacts road conditions, power supply, and daily life. Authorities have issued multiple-level weather warnings, urging residents to avoid non-essential travel and providing temporary shelter and warming supplies for stranded travelers.Airlines stated that, for safety reasons, some flights had to be delayed or diverted. Additionally, ground crews face increased difficulty operating in such frigid conditions, significantly prolonging critical procedures like aircraft de-icing and baggage handling, further contributing to delays. Experts warn that the cold wave is expected to persist in the coming days and advise travelers to closely monitor flight updates and adjust their plans accordingly.
近日，加拿大遭遇罕见的严寒天气，多地气温骤降至零下30摄氏度甚至更低，导致交通系统严重受阻。受极端低温和暴风雪影响，多伦多皮尔逊国际机场、温哥华国际机场以及蒙特利尔特鲁多机场等主要航空枢纽出现大面积航班延误或取消。据加拿大航空部门统计，仅1月上旬，全国就有超过500个航班受到影响，数万名旅客行程被打乱。气象专家指出，此次寒潮源于北极冷空气南下，与来自太平洋的湿气交汇，形成强降雪和大风天气，部分地区体感温度甚至低于零下40摄氏度。这种极端天气不仅对航空运输构成挑战，也对道路通行、电力供应和居民日常生活带来严重影响。政府已发布多级预警，呼吁民众减少非必要出行，并为滞留旅客提供临时住宿和保暖物资。航空公司方面表示，出于安全考虑，部分航班不得不推迟起飞或改道备降。同时，机场地勤人员在极寒条件下作业难度加大，除冰、行李装卸等流程耗时显著增加，进一步加剧了航班延误。专家提醒，未来几天寒潮仍将持续，建议旅客密切关注航班动态，提前做好行程调整。
