There is an extraordinary case out of British Columbia where a father referenced as CD was arrested after he continued to refer to his biological 14-year-old daughter (known as AB) as "she" and his "daughter" after he transitioned to a male gender.  The Supreme Court of British Columbia, Canada ordered that the child receive testosterone injections without obtaining parental consent. CD opposed the transition as the parent but he was overruled after physicians at BC Children's Hospital who decided the girl should receive testosterone injections. The father continued to defy gag orders, including a bar on his trying to persuade with his own child to wait before making such a change.

We have previously discussed how such pronoun disputes (called "misgendering") lead to criminal investigation in other countries like Great Britain.

The Canadian courts withheld the father's name but he has since gone public in interview and has a GoFundMe site under his real name.

Previously, in a 2019 decision, Justice Gregory Bowden rejected the parent's view as largely immaterial:

In view of the established law regarding the right of a mature minor to consent to medical treatment and the assessments of a number of physicians that A.B.has capacity to consent as well as the evidence of his health care providers that the proposed treatment is in A.B.'s best interests, there is no serious question to be tried.
