Canada's 2025 Citizenship-by-Descent Rule Change
Briefing summary
- Canada changed its citizenship-by-descent rules on December 15, 2025, when Bill C-3 amended the Citizenship Act.
- The change relaxes the old first-generation limit in some situations, especially for people born or adopted outside Canada in the second generation or later.
- People born or adopted before December 15, 2025 may have had citizenship restored or given automatically if they were born outside Canada to a Canadian parent, including a parent who became Canadian because of the same rule change.
- People born or adopted on or after December 15, 2025 may need the Canadian parent to show at least 1,095 days of physical presence in Canada before the birth or adoption.
- In June 2026 Canada suspended an unknown number of citizenship certificates issued after the change, underscoring how important the document chain remains.
Canada's 2025 citizenship update is a major change for families with Canadian roots outside Canada. Immigration, Refugees and Citizenship Canada (IRCC) says Bill C-3 changed the first-generation limit to citizenship by descent and took effect on December 15, 2025.
Before the change, Canadian citizenship by descent was generally limited to the first generation born outside Canada. That meant a child born abroad to a Canadian parent could often be Canadian, but the next generation born abroad was usually blocked. Bill C-3 removes that limit in some situations, but it does not remove the need to prove each required fact and family link.
What changed
IRCC now treats some second-or-later generation cases differently. The key question is no longer simply whether the person is beyond the first generation born abroad. Timing matters, and so does the Canadian parent's connection to Canada.
For births or adoptions before December 15, 2025, IRCC says citizenship may have been restored or given to people born outside Canada in the second generation or later. IRCC says that in most cases, a person born before that date outside Canada to a Canadian parent is automatically Canadian. That is still a legal conclusion that depends on the family facts and supporting records. IRCC also says the rule can apply where the person's parent became Canadian because of the same 2025 changes.
For births or adoptions on or after December 15, 2025, the rule is narrower. A person born outside Canada in the second generation or later may be Canadian if their parent was also born or adopted outside Canada to a Canadian citizen, and that parent spent at least 1,095 days in Canada before the person's birth. For adopted children, the same 1,095-day test applies before the adoption.
Who should recheck their status
This update matters most for people who were previously told they were outside Canada's first-generation limit. These are reasons to recheck status, not guarantees of proof. Cases worth reviewing include:
- A person born abroad before December 15, 2025 to a Canadian parent who was also born abroad.
- A person whose parent may now be Canadian because that parent was born abroad to a Canadian citizen.
- Families with a Canadian grandparent or older direct ancestor where the citizenship link may now move parent-to-child through the intervening generations.
- Adopted people born and adopted outside Canada in the second generation or later.
- Anyone who applied under IRCC's interim measure after the December 2023 Ontario Superior Court decision on the first-generation limit.
The change does not take citizenship away from anyone. IRCC states that people who were already Canadian before Bill C-3 became law remain Canadian.
Proof still matters
The rule change can operate automatically in law, but a person still needs proof. IRCC says people who think they became Canadian because of Bill C-3 should apply for a citizenship certificate to confirm and document the status.
That certificate matters in practice. It can support a Canadian passport application and reduce delays when entering Canada. IRCC advises people who may be Canadian to apply for proof of citizenship first, then use the certificate to apply for a Canadian passport before travelling to Canada. The practical risk is that IRCC can still scrutinize the file, especially where the claim depends on older family records, replacement records, translations, or a multi-generation chain.
People with an in-progress application under the interim measure do not need to file a new citizenship certificate application. IRCC says those files will be processed under the new rules.
June 2026 certificate suspensions
CBC News reported on June 15, 2026 that the federal government had suspended an unknown number of Canadian citizenship certificates issued to people who became eligible after the late-2025 change. Some described receiving notices requiring recipients to return certificates while IRCC reviewed their files, with documentation concerns focused on whether records came from original source authorities or whether applicants had adequately explained why original-source documents could not be obtained.
This reporting does not change the Bill C-3 eligibility rules, but it does change the practical approach. Applicants should treat document quality as critically important. A certificate is powerful proof, but users should pay close attention to any later IRCC notice, preserve every original-source civil record they can obtain, and avoid irreversible moves based only on a newly issued certificate if the file is still vulnerable to review.
Citizeo context
Citizeo users who think they may have a strong Canadian citizenship claim, or who may already be Canadian under the statute, should plan to put together a carefully documented citizenship certificate application.
Practical takeaways
- People with Canadian parents or direct Canadian ancestry should recheck Canadian citizenship status if an older first-generation-limit rule was the only reason they were excluded.
- People born or adopted before December 15, 2025 may have stronger claims than people born or adopted after that date.
- For new second-or-later generation cases from December 15, 2025 onward, the Canadian parent's 1,095 days in Canada is likely the central evidence question.
- Citizenship status, proof of citizenship, and travel documents are separate. A person may have citizenship in law but still need a citizenship certificate and Canadian passport before travel.
- Original-source documents matter. CBC's June 2026 reporting on certificate suspensions shows that weak or incomplete documentation can remain a practical problem even after a certificate has been issued.
- Users should confirm directly with IRCC or a qualified Canadian immigration professional before relying on a result.
