Citizenship by descent unlimited in Canada after Dec 15 2025
Canada’s Bill C‑3, effective 15 December 2025, removes the one‑generation cap on citizenship by descent, allowing individuals with Canadian ancestors beyond their parents to claim citizenship. The change applies to anyone with an unbroken line of Canadian‑born ancestors, regardless of how many generations were born abroad, and it supersedes the previous limit that stopped after the first generation.

Les détails
- Annoncé par
- Bill C-3
- Entrée en vigueur
- December 15, 2025
- Règle précédente
- Before December 15, 2025, citizenship by descent could only be passed down one generation when two generations were born abroad.
- Nouvelle règle
- The law now allows citizenship by descent to be passed through any number of generations, as long as each link in the line is a parent‑child relationship.
Legislative background
Bill C‑3 was enacted to modernise Canada’s citizenship framework. The legislation took effect on December 15, 2025 and specifically targeted the restriction that limited citizenship by descent to a single generation born outside Canada. By removing this cap, the government aims to reflect the realities of families whose Canadian lineage stretches across multiple generations abroad.
- Bill C‑3 became law on December 15, 2025
- Goal: align citizenship rules with multi‑generational diaspora
Removal of the one‑generation limit
Under the previous rule, a child born abroad could inherit citizenship only if the parent was a Canadian citizen at the time of birth. If the grandparent was Canadian but the parent was born outside Canada, the line stopped. The amendment eliminates that ceiling, permitting the citizenship chain to continue indefinitely, provided each link is a direct parent‑child relationship.
- No longer a cap on the number of generations
- Parent‑to‑child transmission remains mandatory
Practical implications for claimants
Applicants must now demonstrate an unbroken line of Canadian status from the ancestor born in Canada down to themselves. Evidence can include birth certificates, naturalisation records, and any official documents confirming the ancestor’s Canadian citizenship at the time of each subsequent birth. The change does not alter the requirement for a direct parent‑child link, but it expands eligibility to grandchildren, great‑grandchildren and beyond.
Those whose earlier applications were rejected because of the one‑generation rule may consider reopening their case, using the same documentation that proved the ancestor’s status.
- Proof of each parent‑child link is still required
- Earlier refusals based on the limit can be revisited
