Canada has introduced new citizenship-by-descent provisions following the passage of Bill C-3, creating fresh opportunities for some people with Canadian ancestry to qualify for citizenship.
The legislative changes, which took effect on December 15, 2025, remove the previous first-generation restriction for certain individuals born outside Canada before that date, although eligibility will still depend on each applicant’s circumstances.
The revised rules expand access to Canadian citizenship for some descendants of Canadian citizens, but they do not automatically confer citizenship on everyone with a Canadian family connection.
First-generation restriction removed
One of the most significant changes under Bill C-3 is the removal of the first-generation limit for eligible individuals born abroad before December 15, 2025.
The amendment means some people who were previously excluded because their Canadian lineage extended beyond the first generation born outside the country may now qualify for citizenship by descent.
Proof of citizenship remains essential
Meeting the eligibility requirements does not automatically establish Canadian citizenship.
Individuals who believe they qualify under the new provisions may still need to obtain a Canadian citizenship certificate, which serves as the official document confirming their citizenship status.
The certificate is required for applications such as obtaining a Canadian passport and accessing rights and benefits available to Canadian citizens.
Family records are required
Applicants must provide documentary evidence linking each generation to demonstrate their claim.
Relevant records may include birth certificates, marriage certificates and other official documents establishing the relationship between the applicant and their Canadian ancestor.
Immigration, Refugees and Citizenship Canada stated that applicants must provide “proof of parentage and Canadian citizenship for your Canadian parent, grandparent and parental ancestor as applicable.”
The documentation is intended to establish a clear family connection throughout the relevant generations.
Individual circumstances may affect eligibility
Having a Canadian parent, grandparent or other ancestor does not necessarily guarantee citizenship.
Eligibility may be affected where, for example, a parent renounced Canadian citizenship before the applicant was born or where a parent only became a Canadian citizen after the applicant’s birth.
Given the complexity of some family histories, applicants with unusual circumstances may need professional guidance before beginning the application process.
Family history should be reviewed before applying
Prospective applicants are advised to verify their family’s citizenship history before submitting an application.
This includes confirming where relevant relatives were born, when they acquired Canadian citizenship, whether they changed their names and whether any family member formally renounced citizenship.
Applicants should also gather all available official records needed to establish the required family links.
Although the revised law may enable more people to qualify for Canadian citizenship by descent, eligibility will continue to depend on individual family histories and the availability of supporting documentation.
Understanding those requirements and assembling the necessary records before applying can help ensure a smoother citizenship verification process.
