An eight-car crash left a section of Highway 7 in York region, west of Yonge Street, temporarily closed on Wednesday morning.
About six people were sent to hospital, according to Sgt. Laurie Perks, spokesperson for York Regional Police. All of them have non life-threatening injuries.
The roads were covered with snow at the time but Perks said investigators are not sure if the slippery road conditions caused the crash.
However, snowy conditions are linked to several other crashes across the northern reaches of the Greater Toronto Area.
One driver just giggled and said, "it's a little snowy out here" as a tow truck prepared to tow his vehicle from an accident scene near Highways 400 and 9.
At the collision reporting centre at Lawrence Avenue East and Howden Road, tow trucks had to wait in line before bringing in vehicles for assessment.
"It's extremely busy. Just about any bridge going over the highway anywhere was totally iced up," said tow truck driver Paul McCormack. "A quarter-inch of ice. Lots of multi-car (pile-ups), just people slipping and sliding."
In terms of snow, the GTA got off relatively easily.
In London, a two-hour drive southwest of Toronto, about 10 centimetres of snow fell, with snow squall warnings in effect into Wednesday evening for much of southwest Ontario.
Ottawa got about 15 cm. Thousands of Ottawa-area homes and those across the Ottawa River in Quebec lost hydro as a result fo the dumping. Most Ontario customers should have their hydro restored by late Wednesday, but Quebecers might not get their power back until Thursday.
Toronto will have clear, cold weather overnight, with a low of -2. However, temperatures will start to rebound on Thursday, reaching 9 degrees before hitting 14 on Friday -- just in time for Halloween.
