Canadian records.
Build the chain.
Keep the source.

We searched Canadian censuses and church records, contacted archives when a baptism could not be found, ordered archival copies, and connected Canadian records to U.S. passenger and naturalization evidence. This hub shows the research trail—and separates genealogy evidence from current citizenship requirements.

Bill C-3 evidence

Current proof rules are source-focused.

Bill C-3 came into force December 15, 2025. IRCC's current proof-of-citizenship instructions say applications involving earlier generations must be supported by authentic, reliable and verifiable documents for each relevant generation, issued by the authority that created or keeps the record.

Original authority matters

IRCC says third-party genealogy records alone are not enough when an official record should exist. Genealogy sites are useful for finding the trail; the application evidence should come from the original authority.

Missing record? Document the search.

If an official record cannot be provided, IRCC says to explain why and show proof that you tried to obtain it—for example, correspondence from the responsible archive confirming that the record is unavailable.

Census & manifests can matter

IRCC's current examples of alternative evidence include census records and boat manifests, along with baptismal, naturalization and other official records.

Certification is not always required

Library and Archives Canada currently says certified copies are not required for Bill C-3 proof applications when LAC is the original authority; downloaded records may be submitted with their source/provenance description. Always follow the current IRCC instructions for your case.

Important: this section explains the document workflow, not whether a particular person is a Canadian citizen. IRCC says people who think they became citizens under the new rules should apply for a citizenship certificate to determine and document their status.

Official sources

Citizenship rules and document instructions can change. We keep firsthand research examples separate from the current requirements published by IRCC and Library and Archives Canada.
