Freezing rain and black ice could be a big problem today for much of central Ontario.

Environment Canada says rain will change to freezing rain as the mercury dances around the 0 C mark for most of the day.

Weather officials warn there could be several millimetres of freezing rain accumulation before this evening. They say the drive home from work will likely feature icy roads.

Environment Canada says the most significant freezing rain is expected in Dufferin County, the Caledon area and places with higher terrain.

Freezing rain is forecast to transition back to rain overnight, as temperatures begin to rise.

At the same time, a special weather statement has been issued.

The statement is in effect for:
