A windchill of just under 78°C is *not* common anywhere I'm aware of in Canada. There are usually a handful of days each year in places like Fort McMurray that will hit windchill values in the -40-60° range, otherwise most of the population won't experience anything colder than -30° on the coldest of days. Here in SW Ontario we just had a couple days touching -20° windchill on -13° real temperature, and those will probably end up being the coldest days of the season/year.
