Environment Canada issued a freezing rain warning this afternoon (Saturday) at 1:46 p.m. calling for another round of snow on Sunday morning, which would be mixed with ice pellets Sunday afternoon.
Another round of snow will develop overnight.
"Surfaces such as highways, roads, walkways and parking lots may become icy and slippery", Environment Canada says.
The weather agency says between two and five millimetres are expected to fall with a potential high of 10 millimetres over the northern end of Montreal. "Be prepared to adjust your driving with changing road conditions".More news: Canada Wins First Two Medals at Winter Games

It's expected the rain will change to flurries later Sunday afternoon or evening.
Freezing rain warnings are issued when rain failing in sub-zero temperature creates ice buildup and icy surfaces.
The latest bout of winter weather comes after Toronto received 6.8 centimetres of snow Friday afternoon, wreaking havoc with the afternoon commute.
