On Wednesday snow is expected across parts of the Golden Horseshoe and eastern Ontario.
Snowfall amounts between 5 and 10 cm are expected near the St. Lawrence Valley.
The snow will cause reduced visibility and winter driving conditions meaning roads will be slippery and snow-covered.
Flurries are expected on Wednesday night for areas southeast of Georgian Bay and Lake Huron. The flurries will reduce visibility although significant accumulation is not anticipated.
