It is currently -1 to -3 in Montreal and -2 to -7 in Quebec (city). So yes folks literally freezing. It will remain so (down to -35) for the next 4 months.
Oulu Finland has plenty of biking in the winter, despite its extreme northern latitude. It's about infrastructure and investment.
People wear appropriate clothing for the weather. Those temperatures are no reason to stop biking. People do not "literally" freeze when it's below 0.
Is was like that in the Netherlands about a week ago. It really doesn't make a difference.
Eh, biking in the cold isn't really worse than walking in the cold. The snow is a bigger issue.
Helsinki hits more or less the same weather, people cycle there just fine. It's only a matter of infrastructure and gear.
