So, do people go to work like nothing's happened when it is that cold? The coldest I've been involved in was -10ºF with a high temp of -5ºF. The snow was extra crunchy and LOUD when walking on it. We had utility lights on the engine blocks at night. They now have heated dipsticks; is that what they use in Canada and other places that get cold?
Most cars will start without a block heater, as long as they get some running every day, till maybe -20C (roughly 4/5F)
But when it hits -20C or so, we use electric (corded) block heaters for cars/trucks:
https://en.wikipedia.org/wiki/Block_heater except if running diesel fuel--in which case, the smart money is one keeping the thing running 24/7 when anywhere outside a heated garage. Most of us who can will remote-start our vehicles about 10-15 minutes before we drive. Anyone else who drives, goes out and starts it, and comes back inside for 10 or so (2 sets of keys).
And, pretty much, we just keep on going. Dress for the cold, and lots of us make sure our car is equipped for being trapped away from home if we're going anywhere off a well-travelled highway, or for any long distance.
At -20/25 (around -5F) , though, life isn't all that hard. Once winter is well in, it's unlikely most living up here would do up their jacket to walk down a street or from the car to a house--you'd
wear the jacket (unless it's just across the street, then maybe not.) Really, except for the darkness from 5PM to 9AM, most folks up here don't think much about -20C; it's normal. Cold and kinda crappy and lots of indoor time--except for winter sports (hate 'em).
Wind chill counts. -20C with no wind is easy to deal with. -20C with a strong wind can be
very brutal, quickly painful on any skin that's exposed. At -20C, adding a 10mph wind makes it -30C (-22F).
-40C/-40F (same/same) is when things start to break, and life requires lots more care, then. Hypothermia is a danger even at
plus 50F if you're not adequately dressed--so -20, even, is quite dangerous, and you can't forget that.
-40C is frostbite in a couple of minutes, and severe damage in 10.
When it first hits -40, the schools close, but that's only till they get prepared if the spell lasts long enough--a day or two, it might stay closed. At -30C (wind chill, not actual), most care agencies won't transport for anything but an emergency.
Otherwise, business as usual, for winter.
