How common are these frigid Winnipeg temperatures?

On Friday Environment Canada issued an extreme cold warning advisory as temperatures dipped below -30 C in Winnipeg.

While 2017, will be below average (10days colder than -25 C so far), 2008 registered 33 days where the temperaturesdipped below -25 C.
