Toronto is digging itself out from the largest snowfall ever recorded in the city. Some areas saw nearly 60cm of snow. Toronto's Pearson International Airport was hit hard, with over 500 flights cancelled Sunday. This January already set records at Pearson, with 88.2cm of snow—the snowiest month since 1937. The weekend storm covered much of North America and forced several school boards to close schools on Sunday evening, giving students their second snow day this month. Toronto city officials warn it could take several days to clear snow from streets. City Manager Paul Johnson said, "This is going to be a plowing day, and then we’re going to have to shift into removal time once we get through today and into tomorrow." Staff and families usually get school closure notices early in the morning. The snowy conditions led to more than 430 crashes in Toronto and 200 in nearby areas, including one fatal accident. Police cautioned drivers about roadside snowbanks made by plows that might cause cars to flip off highways. Downtown roads and residential streets remain tough to drive on. Toronto's transit system, serving over 1 million daily riders, faced delays and closures. A streetcar even derailed, and some subway lines above ground were disrupted by heavy snow. The city is focusing on clearing main roads first and using the PlowTO GPS tool so residents can track snowplows clearing streets. Beyond Toronto, the snowstorm caused flight cancellations in the US and power outages due to ice storms. At least 13 deaths linked to the bad weather have been reported. Despite challenges, many Torontonians took to nearby streets to ski and enjoy the sunny winter day. Children with sleds and shovels measured the vast snow cover, relaxing during the long weekend. CP24 meteorologist Bill Coulter said Toronto’s location by Lake Ontario brought extra moisture that teamed with Arctic air to create the "monster" snowstorm, with the northern areas seeing the heaviest snowfall. “What a winter wallop for Toronto,” he said.
