The first storm of the season brought a nasty mix of winter weather to Waterloo Region and Guelph, creating slick conditions and snarling traffic across much of the province. 

A Texas low brought ice, snow and rain to all of southern Ontario on Tuesday, with warming temperatures turning the freshly fallen snow on the ground from Monday evening into a slushy mess. 

The system was the first taste of winter driving for commuters, who until now had clear roads due to record-breaking warmth that's seen temperatures in many parts of the province as high as 10 C above the seasonal average. 

Collisions 'a low number'

Dozens of crashes were reported in southwestern Ontario and provincial police blamed 300 collisions in the Greater Toronto Area since Monday evening on the weather.

In Waterloo Region, Staff Sergeant Jim Strand said there were 19 collisions since 5 p.m. Monday. 

"Only three were listed as weather-related," he wrote in an email to CBC News. "Two of those 19 collisions were parked cars hit by plows. I guess you could say that's weather-related as well."

In Guelph, there were at least eight crashes, all of which were blamed on the late December bout of winter weather.

"To be honest, that's actually pretty good," Guelph Police Service spokesman Const. Mike Gatto said Tuesday. "I hate to say it but that's actually a low number from what we would have expected on a day like today."
