It's happening. The polar vortex will be plunging down on Canada beginning on Friday, February 5.
By Sunday, some parts of the region will struggle to reach even the negative 30-degree mark, with wind chills making it feel closer to -40s and -50s.

Parts of Alberta and Saskatchewan should brace for snow up to 10 centimetres on Friday.
Meanwhile, arctic air will be sweeping through, covering the Prairies with unrelenting cold.
Even in the middle of the day, temperatures won't reach as high as -30 C and will likely feel more like -40 C thanks to the windchill.
The Weather Network says that parts of Canada will be more frigid than the Arctic during this intense cold snap.
Sunday will be the worst day by far, so you should probably plan for an indoor day.
Sadly, it doesn't end there, with the "dangerously cold temperatures sticking around for the rest of the week."
