Legal parentage

Parentage rules for donor conception and surrogacy differ across provinces and territories, covering whether a pre-birth declaration is available, how a non-biological parent is recognised and what paperwork is needed at birth registration. Get provincial legal advice early, before treatment, not after the birth.

Also known as: parentage law, birth registration, declaration of parentage
