Assisted suicide and voluntary euthanasia are both covered by the Carter decision. An example of assisted suicide would be the case of a patient who is prescribed life-ending medication by a doctor and then that patient self-administers the medication. In some situations an individual will be incapable of doing that or may simply prefer to have the assistance of a doctor, and that's why in certain contexts, voluntary euthanasia would be the preference of patients, and, frankly, of doctors as well.
The term used to describe both of these types of end-of-life care is physician-assisted dying. That was the term that was explicitly defined by the B.C. Supreme Court. As well, the Supreme Court of Canada, in striking down both section 14 and section 241(b), made it clear that it's referring to both of those practices. I should add that at no point did the government in the Carter case take the position that a constitutional violation applies to one form of end-of-life care and not to another. That's why I say it is simply inconceivable that the court's decision could be taken to mean anything other than that the criminal prohibition against physician-assisted dying, as I have defined it, is unconstitutional.
