Environment Canada says that the City of Toronto is under a snow squall warning as of the supper-hour, which could result in sudden bursts of snowfall through the rest of the evening and into Friday.
A combination of earlier snow squalls and sub-zero temperatures combined to cause problems for drivers in the city and surrounding areas throughout Thursday.
The temperature fell rapidly overnight, hitting the freezing mark by 5:00 a.m., suddenly reversing the spring-like conditions of Wednesday.
Then came snow and snow squalls, which made the drive all the more treacherous on the roads where a flash-freeze was occurring. Hundreds of collisions resulted on roads across the Greater Toronto Area.
Some drivers complained that there wasn’t any salt on the roads where collisions were occurring.
"There was no salt and that stretch of the road…it’s very dangerous," said Ratko Rakic, whose car was among those caught up in the hundreds of collisions on Thursday.
Peter Noehammer, the city’s director of transportation services, said the salt trucks would normally make a preemptive strike on the roads.
But the rain made that impossible on Thursday.
"If we would have sent them out earlier, that salt would have been ineffective. It would have been diluted and washed away in the rain."
