A Canadian great-grandparent may now support a Canadian citizenship claim in some family lines, but the claim must be proven generation by generation. The key issue is not the great-grandparent alone, but whether each person in the chain can be documented as passing citizenship to the next generation.
Basic Eligibility
Bill C-3 amended the Citizenship Act on December 15, 2025, removing the rule that had blocked citizenship from passing beyond the first generation born abroad.
People born outside Canada to a Canadian parent before that date are now Canadian in most cases, including people whose parents became Canadian under the same change.
For a great-grandparent claim, the family line must be proven step by step:
- Canadian great-grandparent to grandparent
- Grandparent to parent
- Parent to applicant
Immigration, Refugees and Citizenship Canada requires proof of parentage and citizenship for every generation in the chain.
A person with a Canadian great-grandparent and a fully documented family line may already be a Canadian citizen if born before December 15, 2025. For those born on or after December 15, 2025, citizenship depends on whether the parent had 1,095 days in Canada.
If there are gaps in the records, eligibility depends on what can be reconstructed and, for people born on or after December 15, 2025, on the parent’s time in Canada.
The way to confirm status is to apply for a citizenship certificate. The certificate is the official document proving citizenship and is needed before applying for a Canadian passport.
Why Great-Grandparent Claims Are Difficult
A grandparent claim often relies on modern records. A great-grandparent claim may require older records from before Canadian citizenship existed as a legal status.
Canadian citizenship began on January 1, 1947. For Newfoundland and Labrador, the relevant date is April 1, 1949. Before those dates, people who would now be considered Canadian were generally British subjects.
A great-grandparent who lived in Canada before 1947 can still establish the line, but the supporting records may come from older document sets, including:
- British naturalization files
- Evidence of British subject status
- Landed-immigrant records
- Parish registers
- Marriage records
- Archival listings
Many immigrants never naturalized. People born as British subjects had no need to naturalize before 1947, and married women often do not appear clearly in the records because, until 1932, a wife took her husband’s status.
Names can also change across generations through marriage, anglicization, spelling changes, and older naming customs. In Quebec lines, French-Canadian “dit names” can create complications because one document may use one surname while another uses a different related surname.
Example of a Four-Generation Claim
A hypothetical case involves Marguerite, born in Lewiston, Maine, whose great-grandfather came from a Quebec parish near Trois-Rivières before the First World War.
Her documented line ran from:
- Her great-grandfather, born near Trois-Rivières
- His daughter, Marguerite’s grandmother, born in Maine
- Marguerite’s mother
- Marguerite herself
The difficult part was proving each connection. The great-grandfather’s birth had to be established through a Quebec parish register because no provincial certificate existed for that rural birth. A marriage record was needed to connect the grandmother’s maiden name to her married surname.
A single missing link anywhere in the chain would have stalled the claim.
Documentary Standard
IRCC expects each generation to be supported by authentic, reliable, and verifiable records issued by the original authority. An application cannot rely only on third-party records.
In June 2026, IRCC began asking some people whose citizenship certificates had already been issued to return them for review. The issue was that some files relied on genealogy-site printouts or had gaps that had not been formally explained. Those people were still considered citizens, but were asked to prove their status more rigorously.
If an official record cannot be found, applicants are expected to explain in writing why it is unavailable and show what steps were taken to obtain it.
Older claims may require working with British records and offices such as the General Register Office or the National Archives.
Practical Steps to Build the Claim
Applicants should start by building a family tree back to the Canadian-born ancestor and identifying the person who anchors the claim.
The next step is to order certified records for each person from the authority that issued them, working forward generation by generation.
Where a surname changes, a marriage record should be added to connect the names.
Where a record does not exist, applicants should request a “no record” letter and write an explanation while building the file.
A great-grandparent claim may require eight or more birth, marriage, and death certificates across several jurisdictions. Some documents may be more than a century old, in French, or from a period before Canadian citizenship existed.
Timing and After Approval
Processing a proof of citizenship certificate currently takes about 15 months at the time of writing, with wait times rising.
Obtaining vital records from multiple jurisdictions, including church or provincial archives for older births, may be the slowest part of the process.
Once IRCC issues the citizenship certificate, the person can apply for a Canadian passport, enter and live in Canada as a citizen, and work anywhere in Canada without sponsorship.
The recognized citizenship status can also become the basis for the next generation’s claim, subject to the rules that apply to people born abroad.
