After you get your PR Visa and CoPR you can land anywhere in Canada, including any port of entry in Quebec. However, after landing, as a FSW or non Quebec PNP, you cannot have intentions of settling in Quebec. So don't provide a Quebec address for your PR card if your are not a Quebec PNP.
As a FSW, once your are admitted in Canada as a PR, you have a constitutional right to move and settles in any part of Canada, including Quebec.
For PNP, they have provincial residency requirements, which I have listed in a blog post.
