Sure, disruption for a while. But people would cope. There's plenty of houses in Canada built to 1800's standards which are surviving fine through -30C winters. The cars, electronics and transport infrastructure isn't radically different there either.
At least here in the UK the plumbing isn't really designed for extended cold periods - meaning pipes often freeze when they come. If that happened every winter it wouldn't take very long for people to retrofit insulation and interior pipes.
Otherwise it's just a question of insulating buildings and having more infrastructure for snow. Snow often causes chaos because it comes so infrequently - there's very few snow ploughs, the trains don't have ploughs, pipes were routed without planning for freezing weather, people don't know how to drive in it, people don't have snow tires. All these things can be fixed in a few years of cold weather.
