I'm not sure if it's better.
Defining informed consent in the Criminal Code for the purposes of one set of provisions and not defining it for others could also create statutory interpretation problems. That's one thing we want to avoid.
There were numerous reasons informed consent wasn't defined for the purposes of the medical assistance in dying provisions. One of them was that it has clear meaning in provincial and territorial health law. It means the patient has to understand and agree to the nature, risks and consequences of the medical procedure.
My understanding from colleagues who worked on the medical assistance in dying legislation was that the medical community wished the health law definition to apply, and not have a definition in the Criminal Code. Because it has clear meaning in law, I would suggest that it's not necessary to define it. You wouldn't want to define it differently from how health law principles have interpreted it.
