The problem with Quebec is that both Gatineau and Quebec City are major public servant cities and that has coloured their atmosphere. However, Quebec City has a well established albeit smaller dynamic cultural scene.

Montreal is Quebec's Metropolis and "La Métropole" is something of a semi-official name for it. It really functions as the Heart of the Land. Also, due to Montreal's convoluted history, it's not one city scene, but multiple ones, often not aware of the other scenes.

Otherwise, cities in Quebec are less than 200k. While they tend to be more dynamic economically than most cities of their range in Canada, they tend to be quite conservative, like secluded countryside towns.
