Your citizenship by descent claim needs proof your ancestor was naturalized. This free list may hold it

Aug 17, 2026News Briefingwww.cicnews.com

Proof of an ancestor’s naturalisation is a required document for Canadian citizenship‑by‑descent applications. If the naturalisation certificate is missing, the Canada Gazette published a free, searchable list of every person who became a naturalised Canadian between 1915 and 1951. The list is held by Library and Archives Canada and can help fill the oldest link in a generational chain.

Who can use the Canada Gazette list

  • Immigrants who arrived in Canada and were naturalised between 1915 and 1951.
  • Ancestors naturalised before 1915 – their records are in provincial court archives, not the Gazette.
  • Persons born in Canada before 1 January 1947 were British subjects; no naturalisation entry exists.
  • Those born in Britain or other Commonwealth countries before 1947 also retained British subject status and usually do not appear in the Gazette.
  • Naturalisations in Newfoundland before its 1 April 1949 entry into Canada were processed separately.

Searching the Gazette database

The database is accessed through the Government of Canada site:

Tips

  • Begin with the surname; add given name or country only if the result set is large.
  • Use an asterisk () as a wildcard to capture spelling variations (e.g., `Fran` returns Frank, François, Franz, etc.).
  • Remember that place names reflect historical borders (a town now in Ukraine may be listed under Austria or Russia).
  • If a search returns no results, consider looking for a spouse, child, or the parent’s entry, because married women (pre‑1932) and minor children were often recorded under a family member’s name.

What a Gazette entry contains

  • Name of the naturalised person
  • Address at the time of naturalisation
  • Occupation
  • Former nationality
  • Date of naturalisation
  • Certificate number followed by a series letter that indicates the record type:
Series Individuals covered
A Adult foreign nationals (referred to as “aliens”)
B Certificates that included minor children
E Naturalisations under earlier local legislation (pre‑1915)
H Married women whose husbands were naturalised

The series letter directs you to the next source of documentation. For example, a Series E entry signals that the original file is in a provincial court record, while Series B suggests the ancestor’s naturalisation may be documented within a parent’s file rather than under the child’s own name.

Using a Gazette entry in an IRCC application

IRCC classifies supporting documents into two tiers. Gazette entries belong to the secondary tier, alongside census records, baptismal certificates, and military records. The primary document for a naturalisation claim remains the original naturalisation certificate.

If the certificate cannot be located, applicants should:

  1. Document all search attempts.
  2. Submit a Letter of No Record from Library and Archives Canada (or the relevant provincial archive) confirming that the requested document was not found.

A Gazette entry alone does not satisfy the primary‑document requirement, but it can demonstrate that the applicant has made a diligent effort to locate the record and may help IRCC locate the original file using the certificate number.

Gazette search vs. IRCC citizenship‑record request

Feature Canada Gazette database IRIRCC citizenship‑record request (Form CIT‑0058)
Cost Free Fee required
Turn‑around Minutes (online) Several weeks to months
Coverage 1915‑1951 naturalisations only 1854‑present citizenship records
Output Name, address, occupation, certificate number, series letter (no scanned copy) Exact name, date of citizenship acquisition, file number, and a copy of the official record (when available)
Use Provides a reference number to request the original certificate from IRCC Direct proof of citizenship (still may require additional documents for descent claims)

A practical approach is to run the free Gazette search first, obtain the certificate number, and then request the full naturalisation file from IRCC if needed.

Common pitfalls that delay applications

  • Single‑spelling searches – names were often recorded phonetically; using wildcards reduces missed matches.
  • Interpreting a blank result as “no naturalisation” – married women (pre‑1932), minor children, and undocumented gaps can produce empty searches despite actual naturalisation.
  • Submitting the printed Gazette page as the sole proof – it is a secondary document; IRCC will still expect the original certificate or a formal “no record” letter.

When the generational chain contains uncertain links, consulting an immigration lawyer can help identify missing documents before investing time in fruitless searches.
