Oh? I’m in Southern Saskatchewan, about two hours away from the US border. It reliably drops to -40 here in the winter. The vast majority of us heat our homes with natural gas furnaces, driven by electric fans. Long power outages in the winter are a very very big deal, and luckily are quite rare. A few years ago we had one that lasted about 12 hours, and the indoor temperature had dropped to about 7C. If it had continued to drop, the first thing would be damaged plumbing/flooding... followed by people who don’t have a large cache of warm clothes starting to have trouble.
