It's evident that people use bicycles in Montreal -- TFA itself attests this.

But if your point is that North American cities all tend to have the same downtown/suburban contrasts, you are quite right.

People who live $Downtown usually have walkable neighbourhoods and perhaps even access to underground transit. People who live outside the centre of the city mostly end up depending on a private vehicle.

Bicycles are part of the mobility culture in Montreal. But Car Cancer has the same effect everywhere.
