I think that the Quebec government will be revisiting this issue in a new bill that would include it. The problem is that a doctor in Quebec cannot currently administer medical assistance in dying to someone with a disability in the province, but could do so if a patient in the same condition were in another province. That's why the acts need to be harmonized. I believe that the Barreau du Québec said the same thing here this morning.
On November 18th, 2022. See this statement in context.
