What is a minor's capacity to end a life-sustaining treatment? I don't know the details as well as probably some of the lawyers of the case, but I believe it was recently ruled on in A.C. v. Manitoba. I know that it's a complex assessment. It takes into account the emotional, intellectual and psychological state and the maturity of the child. The context occurs not just with the child alone but also in the broader context of the family.
Of course, in our culture we look at children as individuals. As adult assessors, we're trying to determine at what point they have the capacity or the intellectual ability that we possess to make our decisions. One thing we forget about is that there's a theory that children actually are one part of a larger organism, that larger organism being the family. It's a very complex decision.
