Most European cities, London for example, don't have snow in the Winter on a regular basis unlike a lot of US/Canadian cities and don't budget for snow clearing devices. So when they do get a lot of snow in a short space of time they are unprepared and have no other way of dealing with it and therefore shut the airports.
