To answer the first part of your question, I believe all provinces and territories do have health profession appeal boards of some sort. Whether or not it's a consent and capacity board, there are health appeal boards where decisions or issues that come up in the clinical setting or health care setting would go. I don't have my jurisdictional chart on that, but that's where I would look if there isn't a tribunal or a board specific to the mental health in the consent and capacity aspects.
