Canadian Citizenship by Descent Eligibility Calculator
Find out in two minutes whether you are already a Canadian citizen through a parent, a grandparent or an earlier ancestor.
This free eligibility calculator asks about your family line and tells you whether you likely qualify for Canadian citizenship by descent, what the answer depends on, and which records your case would need. Since Bill C-3 came into force on December 15, 2025, citizenship passes beyond the first generation: many people born outside Canada are already citizens without knowing it.
Are you already a Canadian citizen?
A few questions about your family line. No cost, no obligation.
Preliminary indication based on the Citizenship Act as amended by Bill C-3 (in force December 15, 2025). Not legal advice: only IRCC can confirm citizenship, by issuing a citizenship certificate.
What does your result mean?
The calculator gives a preliminary answer, not a decision. If you are likely a citizen, the next step is proof: a citizenship certificate from IRCC, which carries a government fee and needs a record for every link in your family line. If your case needs a closer look — an ancestor who died before 1947, an adoption, a renunciation — a Regulated Canadian Immigration Consultant can review your documents before you apply.
