Environment Canada has issued an extreme cold warning, and snowfall warning for the Region of Waterloo, Guelph, Southern Wellington County and Northern Wellington County.

It warns that temperatures could dip below -30 with the wind chill.

Environment Canada also says we could see around 15 cm of snow on Monday, and possibly more closer to the Great Lakes.

The snow is expected to start later Monday morning and continue into the night.

According to Scott Berry, manager of maintenance with the City of Kitchener, a full plow cleanup can cost between $100,000 and $125,000 for one day.

That includes roads and sidewalks.

Expect deteriorating driving conditions as the snow fall begins.
