While the morning commute should dodge most of the storm, travel during the afternoon commute will be impacted due to accumulating snow.

Buses have already been cancelled in the Halton and Niagara regions ahead of the snow fall, but schools remain open. 

The forecast for this week in Toronto according to Environment Canada.

The snow isn't even the worst of it, the temperature today is predicted to stay at -2 , but it could feel like -12  due to the wind chill.

Temperatures will drop even more by Monday night to -8, but will feel like -15 with the wind chill.
