The weather agency said an Alberta clipper has brought snow across the area which “may be heavy at times” that began early Wednesday morning.
However, there is lesser snowfall amounts expected near the Lake Ontario shoreline where a transition to rain or rain-snow mix is expected.
Toronto is expected to see snowfall amounts near 10 cm. Areas north of the city such as Barrie is expected to see closer to 15 cm.

Each type of weather alert will now include a colour — yellow, orange or red — to show the seriousness of the weather event, according to the Canadian government.
Yellow alerts are the most common — this is the alert level for the snowfall across southern Ontario on Wednesday. They are issued when hazardous weather may cause damage, disruption, or health impacts. Impacts are likely moderate, localized, and/or short-term.
Orange alerts are issued when severe weather is likely to cause significant damage, disruption, or health impacts. Impacts can be major, widespread, and/or may last a few days.
Red alerts are rare. They are issued when very dangerous and possibly life-threatening weather will cause extreme damage and disruption. Impacts have the potential to be extensive, widespread, and prolonged.
