From British Columbia’s mountain passes all the way to Labrador, November across Canada is looking at an overwhelmingly snowy start.
After warm, late-October air dominated over parts of Northern Canada, setting records in Nunavut for the warmest October on record, a mass of Arctic air will drive south over the coming days, ushering in cold, wintry air that will fuel this week’s snow threat across the entire country.

Ontario
there will be a few chances for snowfall across Ontario this week, with the first chance forecast on Sunday across the northern region of northwestern Ontario.
The chilliest air will stay around Hudson Bay, so we’ll likely see the snowfall stay north of Thunder Bay and Timmins early in the week.
A subtle shift in the storm track late-week, however, will send the cold air and snow threat south. A low-pressure system will then tap into the chilly air over the Great Lakes, increasing the chances for snow throughout the Great Lakes basin.
