Citizenship by Descent Claimants May Find Proof in Free Gazette Records
Applicants for Canadian citizenship by descent may find proof of their ancestor's naturalization in the Canada Gazette records, a free searchable database maintained by Library and Archives Canada.

A claim to Canadian citizenship by descent can be broken at its oldest link if there is no record of the ancestor who immigrated. This can result in a request for more evidence or a stalled application, especially with processing times now exceeding two years.
Between 1915 and 1951, the Canadian government published the name of every person who became a naturalized citizen in the Canada Gazette. Library and Archives Canada holds those printed lists and runs them as a free searchable database.
Eligibility for the Gazette Records
The lists cover one key group: immigrants who arrived in Canada and became naturalized. Situations in which the Gazette records are relevant include:
| Category | Description |
|---|---|
| 1915-1951 | Immigrants who naturalized between 1915 and 1951 |
| Before 1915 | Provincial courts handled naturalization, and files sit in provincial archives |
| Born in Canada | Before January 1, 1947, people born in Canada were British subjects |
| Born in Britain or another Commonwealth country | Before 1947, British subjects by birth did not need to be naturalized |
Newfoundland joined Canada on April 1, 1949, and naturalizations there before that date went through a separate process.
Searching the Gazette Records
You can access the website to begin the search of your ancestor's citizenship records. Start with a surname, and Library and Archives Canada suggests adding a given name or country only when results run long. Spelling is often the main obstacle, and the database accepts an asterisk as a wildcard.
Country names follow the borders of the time. A place now in Ukraine may appear as Austria or Russia. Note that a blank result does not mean that your ancestor did not naturalize, and it does not kill your claim to Canadian citizenship by descent.
What an Entry Holds
A Canada Gazette entry gives you a name, an address, an occupation, a former nationality, and a date. It also gives you a certificate number with a letter attached, and the letter carries information most researchers read past.
Series A covers adult foreign nationals, Series B covers certificates granted with minor children included, Series E covers people naturalized under earlier local legislation, and Series H covers married women whose husbands were naturalized.
What to Do Next
IRCC divides documents into two tiers, and Canada Gazette records sit on the secondary list. A secondary document does not replace an existing primary document. If you are not able to find a naturalization certificate, you must document your attempts to do so and submit this to IRCC as part of your application.
A Gazette entry moves your file from missing a link to potentially useful, but it is not sufficient by itself. If every other generation rests on a provincial birth certificate and this one rests on a printed list, you still have work in front of you.
Comparison to a Search of Citizenship Records
Compared to a search of citizenship records, the Gazette archive database costs nothing, answers in minutes, and covers 1915 to 1951. It hands you a certificate number and a series letter. It carries secondary weight.
The IRCC search carries a fee and a wait. It reaches records from 1854 to the present and returns the exact name in the registry, the date citizenship was acquired, and a file number.
Mistakes to Avoid
- Searching one spelling can lead to incorrect results.
- Reading a blank result as an answer can be misleading.
- Filing the printed page as your proof is not sufficient.
If you know which ancestor your claim runs through but cannot tell whether your documents establish the full chain, a citizenship lawyer can read the chain and name the gap before you spend months chasing the wrong record.
