In a video posted on Twitter, OPP Sgt. Kerry Schmidt said those crashes included a jackknifed transport truck around Highway 401 and Highway 6, alongside other problems across the region.
"Please, if you are out on the roads, remember, the roads may only look wet but they could be slippery," Schmidt said.
"We still have snow that's flying and blowing across the highways."
