Environment Canada warns: > Extremely cold windchill values between -40 and -50 continue today for most of Alberta. It may be possible to dress for the weather, but 4–6 hours is a very long time to be outside at those temperatures. None of the snowsuits I have found on that site are rated for temperatures below -30°C, and none of the children's suits appear to go below -20°C (though perhaps I am looking in the wrong category).
