On December 15, 2025, IRCC confirmed Bill C-3 is now in force, changing Canada’s “first-generation limit” for citizenship by descent. Many people born or adopted abroad before today who were previously excluded may now be Canadian automatically, while births/adoptions abroad on or after today in later generations can qualify if the Canadian parent proves a substantial connection (1,095 days in Canada).
Key Takeaways
- Bill C-3 took effect on December 15, 2025, and IRCC says it is applying the new rules now.
- Many people born/adopted abroad before today who were blocked by the first-generation limit may now be citizens automatically and should apply for proof (a citizenship certificate).
- For births/adoptions abroad on or after today in the second generation (or later), IRCC requires the Canadian parent (also born/adopted abroad) to prove 1,095 days (3 years) of physical presence in Canada before the child’s birth/adoption.
Bill C-3 citizenship by descent changes now in effect
IRCC published an official update on December 15, 2025 confirming that Bill C-3, An Act to Amend the Citizenship Act (2025), is now in effect. The change targets the long-criticized “first-generation limit” introduced in 2009, which often prevented Canadians born or adopted abroad from automatically passing citizenship to their own children born or adopted abroad.
In plain language: the rules changed in two directions at once. First, many people impacted by older rules (especially those born or adopted abroad before today) may now have citizenship automatically. Second, for future cases (births/adoptions abroad starting today), citizenship by descent in the second generation (or later) is tied to a new “substantial connection” requirement.

What changed today
1) People born or adopted abroad before December 15, 2025 may now be citizens automatically
IRCC states that people born before December 15, 2025 who “would have been citizens” but for the first-generation limit (or other outdated rules) will be Canadian and can now apply for proof of citizenship. This is especially relevant for families where a Canadian parent (or grandparent) was born or adopted outside Canada and the “chain” of citizenship was previously cut off by the 2009 limit.
2) A consistent “path going forward” starts today
For children born or adopted outside Canada on or after December 15, 2025, a Canadian parent who was also born or adopted abroad can pass on citizenship if they can demonstrate, at the time of application, that they spent three years in Canada prior to the child’s birth or adoption.
3) IRCC confirms the new rules apply to current processing
IRCC’s guidance explains that if you already applied under the earlier interim measure, applications still in progress will be processed using the new rules and you do not need to submit a new citizenship certificate application.
Who is affected
The key is understanding (a) your date of birth/adoption and (b) how “generations” are counted in your family history. IRCC generally uses “first generation” for someone born/adopted abroad to a Canadian who was born in Canada or naturalized, and “second generation or later” for someone also born/adopted abroad to a first-generation person.
| Scenario | What it means under Bill C-3 (effective Dec 15, 2025) | What to do next |
|---|---|---|
| Born abroad before Dec 15, 2025 and previously blocked by the first-generation limit | In many cases, citizenship may be restored or granted automatically (depending on your facts) | Apply for a citizenship certificate (proof of citizenship) to confirm status |
| Adopted abroad before Dec 15, 2025 by a Canadian parent who was also born/adopted abroad | You may be eligible to apply through the adopted-person “direct grant” pathway | Gather adoption/legal documents and apply under the adopted-person process |
| Born/adopted abroad on or after Dec 15, 2025 to a Canadian parent who was also born/adopted abroad | Citizenship by descent may be available if the parent proves a “substantial connection” (1,095 days in Canada) | Collect strong evidence of the parent’s physical presence in Canada before the birth/adoption |
| You became Canadian automatically but don’t want citizenship | IRCC notes you may be able to renounce citizenship | Review renunciation consequences carefully before taking any steps |
What to do next
Step 1: Apply for proof of citizenship (don’t rely on assumptions)
Even if you strongly believe you became a citizen automatically today, IRCC’s guidance is clear: you must apply for a citizenship certificate to find out for sure and to obtain official proof. Proof matters for practical reasons like passports, status confirmation, and updating records across borders.

Step 2: If the “substantial connection” rule applies, build an evidence package early
Where your case falls under the on-or-after December 15, 2025 rules, the requirement is about the Canadian parent’s cumulative physical presence in Canada (1,095 days) before the child’s birth or adoption. Start collecting evidence that is difficult to dispute, such as school transcripts, job records, leases, tax slips, medical records, and travel history. The stronger the file, the smoother the assessment tends to be.

Step 3: If you filed under the interim measure, monitor your file (but don’t reapply)
If you already submitted a citizenship certificate application during the interim period, IRCC’s posted guidance indicates it will process your application using the new rules and that you do not need to submit a new application. The practical next step is to ensure IRCC has your current contact details and to respond quickly to any document requests.
Action Checklist
- Apply for a citizenship certificate to confirm automatic status
- Prepare evidence for the “substantial connection” requirement
- Ensure IRCC has current contact details
- Respond promptly to IRCC document requests
- Consider professional advice for complex cases
Conclusion
Bill C-3 significantly changes the landscape for Canadian citizenship by descent. It offers a pathway to citizenship for those previously excluded by the first-generation limit, while setting clear criteria for future generations. For anyone impacted, understanding these changes and taking proactive steps is crucial.
