I don't know if the objective is to start a fight over areas of responsibility, but I'm going to give you a somewhat political answer.
Land use, I think, is both a federal and provincial jurisdiction. We have a big country. Quebec is a big province that covers 1,500,000 square kilometres and has a population density of 5.6 inhabitants per square kilometre. It's completely disproportionate to other destinations that we compete with.
To digress somewhat from your question, our airports and access to our regions are also important from both federal and provincial standpoints. I don't think one government can leave full responsibility to the other.
