After a blast of winter that dumped as much as 30 cm of snow on parts of southwestern Ontario, the region will get a short reprieve before another storm hits early Sunday morning.
Environment Canada has put much of the region under a winter storm watch, as a new system could dump another five to 15 cm of the white stuff on the region.
"After a brief break today from nasty winter weather in the wake of Friday's winter storm the next disturbance in the series will threaten to intensify into a winter storm tonight and Sunday as it moves from the U.S. Midwest into southern Ontario," the warning said.
Unlike Friday's storm, this second system is expected to also wreak havoc across Quebec and the Maritimes.
Environment Canada has already put parts of Quebec, including Montreal, under a snowfall warning, with accumulations of 15 cm or more expected.
Toronto's Pearson International Airport, the country's busiest, will be scrambling to catch up on holiday flights today, after the storm forced the cancellation of more than 300 flights on Friday.
The storm buried Hamilton, Ont., under 30 cm of snow.
