I've written before about how having someone committed to a facility due to mental illness is difficult in Canada, and holding them for over 48 hours is very very difficult.. again, this is one of those frequent times that using an American paradigm to speculate on what might happen to JYYS just doesn't work..
I don't feel like typing, so I'll just quote from

also,
On top of that there are matters regarding the Canadian Charter of Rights that have not been fully resolved.
Then there's the additional matter of needing someone to petition either a physician or the court to get the involuntary hold. Unless that person is a family member or caregiver, it won't happen.
In a very brief search, there have been no non-criminal related successful psychiatric holds in BC that have not been initiated by a caregiver/family member.
File this one under Fantasy Outcome... Unless JJYS kills someone and succeeded at convincing a judge or jury that he was suffering from a
mental disorder that rendered him incapable of appreciating the nature and quality of the act he was committing.
