A freezing drizzle advisory has been put into effect for Northwestern Ontario. 

Periods of freezing drizzle are occurring this morning. The freezing drizzle is expected to change over to snow early this afternoon.

Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Freezing drizzle can produce thin, hard-to-detect layers of ice. Take extra care when walking or driving in affected areas.

Highways in Northwestern Ontario are reported as slick and snow-covered and those who don't need to travel for necessary reasons are asked to stay put.
