That reminded me of my own arguments with the Registrar General's staff. When my university-age daughter lost her birth certificate and needed a replacement in a hurry to avoid paying foreign student fees at registration, I attemped to buy a new one for her by placing an order at the government buildings in Toronto (the main facility is in Thunder Bay in Northern Ontario.) They told me I couldn't order the certificate-- because she had reached the age of majority and it "would violate her privacy". I did a number about being one of the participants in the birth event and knowing all about it. My signature was in fact on the form. The supervisor relented and let me order the certificate.
A few years later I was the executrix of the estate of my mother's cousin. The deceased's next-of-kin was an elderly man living in Las Vegas, Nevada. He asked me to get him an official copy of his sister's death certificate. I could have mailed him a form for his signature but I decided to challenge the Ontario Registrar General's clerks again. As expected they said that I couldn't order the certificate-- only the next-of-kin could. I explained that I had provided all the information on the death registration and it bore my signature. They really had no idea whether the deceased had a brother, where he lived and what his signature looked like. They relented and let me order the death certificate.
