City of Sydney Relationships Declaration
Other institutions such as the Registry of Births Deaths and Marriages no longer accepts an Australian Marriage Certificate as a form of ID – this creates an equal situation for both opposite sex and same sex couples as both are not allowed to present their relationship certificates as a form of ID.
Canadian nationality law
As those who were born in Canada normally acquired citizenship at birth under both 1947 and 1977 Acts, birth certificates issued by the provincial or territorial government are usually considered by Immigration, Refugees and Citizenship Canada as adequate proof of citizenship. There are, however, complications when the person failed to acquire Canadian citizenship because of the exceptions listed under subsection 3(2) of the Act. As the federal government does not keep records of the immigration statuses of parents at birth, a person may be recognized as a Canadian-based solely on his or her birth within Canada when, in fact, he or she does not possess Canadian citizenship under subsection 3(2). Deepan Budlakoti, a stateless man born in Ontario, was twice issued a valid Canadian passport based on his Ontario birth certificate before the federal government realized that he is not a Canadian citizen under subsection 3(2) and revoked his Canadian passport.
