Since December 15, 2025, individuals with Canadian ancestors can claim Canadian citizenship by descent if born before that date.

To verify eligibility, applicants must provide documented proof of a direct lineage from their Canadian ancestor. Starting with resources like FamilySearch and Ancestry can kickstart the search process, while additional tools focused on Canadian records, including Quebec archival records, can be invaluable.

It’s important to note that these tools provide leads, not definitive proof. The Immigration, Refugees and Citizenship Canada (IRCC) requires official documents from the original issuing authority for confirmation.

Prior to delving into the search, CanadaVisa’s citizenship by descent calculator can help determine the generational link for the claim, guiding the search process.
