Yes, the issue was about consent and the effect of providing consent to disclosure of information. I was simply making a point that an individual who is deemed at law to be mentally incapable is not able to provide valid legal consent for anything. That would apply also to a minor. In British Columbia the age of majority is 19. Anyone under the age of 19 cannot provide consent except in certain statutory exceptions. For example, they might be able to provide consent to treatment if they meet the mature minor test for medical treatment, but they would not be able to enter into a contractual relationship, for example, without intervention of the court.
There are other provisions to protect. The idea of consent by someone who doesn't have capacity at law to provide it was my point.
