Toronto is under a winter weather travel advisory after light snow turned to freezing drizzle in parts of the city on Monday morning. 

Environment Canada is warning of icy conditions on untreated roads. 

The national weather agency says the threat should end around the noon hour, when the temperature is expected to rise above zero and periods of rain are in the forecast. 

The areas affected by the advisory include western Toronto to the Kitchener area. Fog patches that reduce visibility were also possible in some areas, Environment Canada said. 

The city said in a series of tweets that it is salting main and local roads.
