I remember it getting that cold a few times when I lived in Canada. My nose spent the entire winter frozen and I learned to be a mouth breather for 6 months of the year.
I don't miss those winters. I'm going to invest in some beach front property on Hudson's Bay and wait for nature to take its course.
I'm not even worried it will be flooded with the rest of the beaches.
I've heard the areas covered by ice are still rising because all that weight is gone. So time has more good news for Canada.
