It has been unusually bad for what we’re used to. Any given country is comfortable with its expected weather. If the weather gets out of that country’s comfort zone it copes badly. So weather that might be normal for canadians (because they are used to it) is crippling for Brits.
I live in the Isle of Man which gets a tiny bit of the influence of the Gulf Stream by being in the middle of the Irish Sea. Consequently it’s slightly warmer here than the same level of latitude in England. So it very rarely snows here. But it did recently. Many roads were sheets of ice. Many cars acquired a covering of snow which turned into ice and stayed on the cars for almost a week.
I couldn’t ‘arm’ my car because when it’s this cold the alarm’s electronics are tricked into thinking the alarm battery is low (so an ‘alarm battery is low’ alarm goes off, which is quite loud)
