How do you know how I got my information? Perhaps you need to live in Quebec, or study more Quebec history. You are clearly misreading the data. The fact that people declare themselves Catholic in this situation means very little when it comes down to actual tenets of faith or Catholic identity. Getting married in the Catholic Church? A public gesture, not a spiritual one, in Quebec. You're confusing the motions with spiritual intent. 

Check out the companion article in NCR, about the Quebec bishops' visit to Francis, in which they discuss the profound secularization of the society and the extent to which the "church is pushed almost completely out of most people's lives."
