"This week is going to be the snowiest of the year so far," said meteorologist for Environment Canada Marie-Eve Giguere. 

The forecast in Montreal for Monday night calls for flurries and winds gusting up to 80 km/h and a low of –16 C.

Storm expected Tuesday evening

Giguere said the snowfall starting early Tuesday evening could see Montreal covered in 15 to 20 centimetres by Wednesday morning. There are also strong winds expected for Wednesday morning which will cause blowing snow and slow the morning commute. 

Environment Canada also has a special weather warning of a major storm en route for the Montreal region and much of southern, central and eastern Quebec. 

Freezing rain made it a messy Monday

The City of Montreal had 1,000 workers and 1,000 pieces of equipment out spreading salt and abrasives on streets and sidewalks in a bid to make them safe for traffic and pedestrians despite icy conditions. 

City spokesman Jacques-Alain Lavallée said the arrival of freezing rain on a Monday brought the added challenge of increased pedestrian traffic on streets and sidewalks.

Urgences Santé, which coordinates 911 and emergency response services in Montreal, reported more calls than usual on Monday morning, with many reporting injuries related to the freezing rain. 

"We've been receiving many calls since early this morning — about 100 more calls than is usual, mostly for falls, for minor injuries like contusions but also for fractures," said Benoit Garneau, a spokesman for Urgences-Santé.

He said icy stairs, sidewalks and driveways were the main culprits.

The organization tweeted to remind people to exercise caution on the streets and sidewalks and included a link to Canada Safety Council tips on safe winter walking.
