Between areas where snowfall was the norm Thursday and Friday and areas where squalls moved in during the Friday morning rush, it’s clear hundreds of crashes occurred across Ontario.

In Waterloo Region alone, 150 collisions had been reported by mid-afternoon Friday – not including any of the crashes that occurred on the OPP-patrolled highways.

“When vehicles started driving on that snow, it became ice very quickly,” said Waterloo Regional Police spokesperson Olaf Heinzel.

None of the local crashes were fatal, but three deadly crashes did occur elsewhere in the province, on OPP-patrolled roads.

Around 4 p.m. Thursday, one person was pronounced dead at the scene of a two-vehicle crash on Bruce County Road 12 in Carrick Township, near Teeswater.

He was identified Friday as Marcus Urbanowicz, a 59-year-old London resident.

Later Thursday evening, a car struck a piece of farm equipment near Port Burwell in Elgin County, sending it into a ditch and slamming into a hydro pole.

The driver of the car was pronounced dead at the scene, and later identified as James Holleywell, 65.

Friday morning, Lambton County OPP reported a fatal crash on Petrolia Line in Enniskillen Township.

The driver of a car – 45-year-old Petrolia resident Craig Moffatt – was killed in a crash also involving a farm vehicle.

Elsewhere, Oxford County OPP reported 20 collisions on roads and highways between 6 a.m. and 1 p.m., none of which resulted in serious injuries, while Woodstock Police responded to 16 crashes into the city between 6 a.m. and 3 p.m.

South Bruce OPP also reported 15 crashes in their area between noon Thursday and noon Friday.

"It's frustrating to see this year after year; lives put at risk because drivers don't adjust their driving during winter months, especially during the first snowfall," Acting Insp. Wayne Thompson said in a press release.

Snow squalls continued to batter areas to the south of Georgian Bay into Friday evening, particularly in Huron-Perth and southern Bruce County.

For most areas, Saturday should see a brief respite from snow before precipitation begins anew Sunday.
