You need to apply for a citizenship certificate, if you:
- need to replace or update your citizenship certificate
- want to pass down your Canadian citizenship to your child born outside Canada and you were born in Canada or naturalized before your child was born
- were born outside of Canada and your legal parent at birth or biological parent was born in Canada or naturalized before you were born
- need a document that proves your Canadian citizenship (such as to apply for a passport, job application, pension, Social Insurance Number, etc)
- think you’re a Canadian citizen and want to know for sure
