The snow picked up Monday night and continued to intensify through the day on Tuesday.
The storm affected a large swath of regions extending from Sault Ste. Marie to Timmins, where over 30 cm of snow piled up.
Milder air associated with the system made a brief visit on Tuesday giving some places a messy mix of rain and freezing rain as well.
"Some areas will continue to see flurries on Wednesday, but the snow should taper by the afternoon and evening hours," says Gina Ressler, a meteorologist at The Weather Network.
Strong winds across the region however, may continue to reduce visibilities in blowing snow. As a result, travellers are urged to allow extra time due to the hazardous road conditions.
Frigid wind chills will also make things feel closer to -30 to -40 in some areas Wednesday, so residents should limit their time spent outdoors.
