I would like to answer your question. When the Civil Code of Québec came into force, on January 1, 1994, the documents that were accepted by Quebec changed. After the events of September 11, the Minister of Relations with the Citizens and Immigration of Quebec announced that only certificates issued after January 1, 1994, would be accepted. I was baptized in Quebec, and my baptism certificate was not an accepted document.
On June 5th, 2007. See this statement in context.
