Through unrelated research, I found that the citizenship card only has the date when the card was printed, and not when I became a citizen. I guess I also received a "commemorative certificate" which is not valid proof of citizenship, but which does have the date I became a citizen. I have no idea where my commemorative certificate is, and I no longer live in Canada, so it's lost for all intents and purposes.
Is there a way to find out when my citizenship was officially granted?
