I lost my citizenship card. What else can I use to prove citizenship?
If you were not born in Canada, you will be required to provide an official government document to confirm your citizenship in Canada.
If you have lost your citizenship card, an alternative document to use with your Pardon application could be your Canadian passport. If you do not have either, obtaining a passport will take significantly less time than awaiting a new citizenship card. Every Canadian is permitted to have a Canadian Passport and applying for this will not cause any further concerns with regard to your criminal record.
