They do. Also people who use bicycles in Montreal are disproportionately males and mostly of the certain age group. That's very apparent if you stay for ~10 minutes near Grande Bibliothèque for example or any other relatively busy piste cyclable. If you call it a 'mobility culture' it a very niche one. Bicycling is a thing for very specific demographics in Montreal in comparison with Amsterdam and even with Eastern European cities.
Interestingly that high schoolers are not biking that much in Montreal, again in comparison. Biking to school was/is an exception where I live(d) in Montreal, i.e. Le Sud-Ouest, NDG.
