Hello! I am in the process of applying for a certificate of Canadian citizenship, and I have a question regarding my parents, who are now both deceased. My parents were naturalized Canadian citizens who emigrated from Finland in 1952; I was born in Canada in 1959. We moved to the US when I was 8, and we all entered the US as permanent residents (green card holders). I became a US citizen in 1993, but my parents remained Canadian citizens until their deaths. I would like to hold dual citizenship for Canada and the US, which is why I am applying for a citizenship certificate. The problem is that I do not have either of my parents' certificates of Canadian citizenship, I only have their last issued Canadian passports. Is there any way for me to find out what their certificate numbers were?
