It must be very worrying at present for people in the US that have EVs and no power as it seems millions are without power and no idea when power will be restored...
		
		
	 
There are several areas across Canada and the USA which are used to dealing with fairly extreme weather and whilst  this may be colder than usual they have probably  already got effective ways of dealing and continuing  to  live under these conditions. Its mainly the big cities in the USA which  are not best set  up for these conditions and yes it's dreadful to hear of deaths due to the weather.
Most  EV drivers don't get  home with a fully discharged battery,  so their car will most likely still have some driving range left very much like ICE drivers (no pun intended).
In fact will more recent  EV's with  Vehicle to Grid or Vehicle to Load capability the fact the car may still have some charge left could help the owner power some of their home,  where an ICE vehicle couldn't.
As others have pointed out with no power most Dino  juice stations can't deliver fuel,  and even if they had hand cranked pumps (and most  don't) with no meterage and the power and telecoms down,  most  people couldn't pay for the fuel anyway.
The Artic Blast  across N. America is likely to  affect both EV and ICE vehicle owners very  much the same.
