Based on everything I've read about this, I think it makes a great deal of sense to say that palliative care needs to be available and that it needs to be an option in any scenario where assisted death is made available.
I would only go a step further to say that we need to think of palliative care as something that is provided to every Canadian who is dealing with a life-threatening illness and is part of their treatment. Managing their pain, dealing with their emotional and psychological needs, helping them to receive care in the best place possible—those will all be part of their treatment right through, with particular emphasis, of course, when people face end-of-life issues and also when they're confronting the kinds of choices you describe.
