The lineage documents for Canadian citizenship by descent

Write one row for each person from the Canadian anchor to the applicant. Record the legal name at birth, later names, date and place of birth, parents, citizenship basis, and the source that proves each fact.

This exposes the weak link early: an absent parent name, an inconsistent surname, an adoption, a naturalization after the next birth, or a record held by an unexpected jurisdiction.

• Civil birth records showing parentage for the applicant and every connecting generation.
• Canadian birth, citizenship, or naturalization proof for the anchor citizen.
• Marriage, divorce, court, or statutory name-change records bridging identity changes.
• Adoption or parentage records where the legal relationship is not shown by an ordinary birth certificate.
• Current applicant identity documents and photographs.
• Translations and translator evidence that meet the current IRCC rules.

1. Is it issued or certified by the authority IRCC recognizes?
2. Does it show the parent, date, or citizenship fact the chain depends on?
3. Does the name match, or is the difference documented?
4. Is the record complete and legible, including both sides and amendments?
5. If it is not in English or French, is the required source-and-translation package complete?

Follow the official issuing authority's search or no-record process and IRCC's current guidance for alternative evidence. The absence of a certificate does not authorize an applicant to substitute an unrelated genealogy source without explanation.

Build a documented search trail: jurisdictions checked, name variants, date ranges, responses, and any official no-record statement. Complex cases may need legal advice.

This is general information, not legal advice. Canadian citizenship law and IRCC forms can change; use the current official instructions for the application you file.
