If you see "parental rights" or "parents' rights" in the context of the autonomy and medical and social welfare of a child within the federal jurisdiction of Canada, it may interest you to note that that concept is fairly antithetical to the established legal approach (as imperfect as it often is). According to practice here — as far as I understand it, based on conversations with lawyers and social workers — the welfare of the child comes first and foremost, and the concept of parental rights is not really a thing, but in the eyes of the courts and the law should be framed rather as parental responsibility. Parents don't have the right to do whatever they want with their children. Parents have the responsibility to the welfare and wellbeing of their children.

"Parents rights" is a gender critical, queerphobic, and ableist dogwhistle. Be on guard when you see it.
