Generally you'd have a backup heat source with an air-to-air heat pump for those really cold days like -15C and colder, like a gas furnace or a heating element unit inside (like with electrical coils). Air-to-air heat pumps are more efficient on warmer days, on colder days they would be less efficient but you'd still have a backup heat source so it would still "work", so the article is still somewhat correct in that sense.

Also, electric baseboard heaters can be quite a bit louder than forced-air systems with a heat pump, so you'd still be better off with a heat pump in those cases.
