The heavy snow made cleanup a daunting task after the storm had abated.
Police say an elderly man has died in Niagara Falls after shovelling snow, the second such incident after Friday's massive storm.
Niagara Regional Police Staff Sgt. Dave Brennan says an ambulance was called to a home in the city's south end Saturday morning when an 80-year-old man collapsed while clearing snow.
The man was rushed to Greater Niagara General Hospital, where he later died.
Brennan says the hospital determined the man died from physical exertion while shovelling snow.
This is the fourth death related to the fierce storm that swept southern Ontario on Friday night.
An 80-year-old woman died Friday morning after she collapsed while clearing snow from her driveway in Hamilton.
Two men died in separate crashes as well.
A 57-year-old Ottawa man died when his car crashed in blizzard conditions along Highway 401 near Prescott, Ontario, while in Pickering, a 49-year-old Oshawa man died in a multi-vehicle collision.
The driver and several passengers of a bus that rolled over near Brockville were also injured.
The storm shut down schools and clogged roads and highways with snow across much of the province Friday, and led to the cancellations of hundreds of flights out of Toronto's Pearson Airport.
That system was eventually absorbed into a powerful Nor'easter that made for a tough weekend in Atlantic Canada
and dumped up to a metre of snow in parts of the United States, where several people lost their lives in storm-related incidents.
