Travellers pass the time at Pearson International Airport Terminal One in Toronto, January 7, 2014. Glacial temperatures gripping large parts of the United States and Canada disrupted thousands of flights on Tuesday, creating more challenges for airlines seeking to recover from recent snow and ice storms. Toronto's Pearson International Airport, which was one of the airports which was hit hardest and had 119 flights, or 19 percent of its total halted, said the gusty winds and extreme cold weather, which Environment Canada said was minus 37 degrees Celsius (minus 35 degrees Fahrenheit) with wind chill, was causing equipment to freeze and posing a safety concern for workers.
