I don't think it should be assumed that there shouldn't be provincial legislation. Medical aid in dying, or physician-assisted death, is related to both criminal law and health. With regard to health, a certain part of Canada has said that it is a matter that is under co-shared jurisdiction. It's a matter that belongs to the provinces, and it belongs to the federal Parliament. It all depends on your perspective on the subject. It all depends on the nature of the intervention of the legislative assembly that is concerned.
I would say that you cannot assume there will not be provincial legislation or that there should not be provincial legislation. What you could do, though, is to just talk with the provinces, discuss with the provinces, and enter into a dialogue and see how there could be concerted action with regard to physician-assisted death in order to give more harmony and coherence to both the federal and the provincial interventions.
As for the Quebec law, I would say very briefly that the Quebec law could be a very good model across Canada, but it doesn't go as far as the Supreme Court of Canada appears to have gone in the Carter decision.
