Updated July 2026. Canada’s citizenship-by-descent rules changed fundamentally when Bill C-3 came into force on December 15, 2025. The old “first-generation limit” — which blocked Canadians born abroad from passing citizenship to their own children born abroad — has been removed and replaced with a substantial-connection test. If you or your children were born outside Canada to a Canadian parent, this law may make you a citizen automatically. Here’s how it works.
What the First-Generation Limit Was
Since 2009, citizenship by descent stopped at the first generation born abroad: a Canadian born in Toronto could pass citizenship to a child born in London, but that child could not pass it to a grandchild also born abroad. Court challenges found this created “Lost Canadians,” and in 2023 the Ontario Superior Court ruled the limit unconstitutional — Bill C-3 is Parliament’s response.
The Two Rules Under Bill C-3
Born abroad before December 15, 2025
The law applies retroactively: anyone born abroad to a Canadian parent before that date — regardless of generation — is generally a citizen automatically. This restores status to many “Lost Canadians” and their descendants. There is no connection test for this group; if this describes you, you may already be a citizen and can apply for a citizenship certificate (proof of citizenship) to confirm it.
Born abroad on or after December 15, 2025
For children born or adopted abroad going forward, a Canadian parent who was themselves born abroad can pass on citizenship only if that parent has a substantial connection to Canada — defined as at least 1,095 days (3 years) of cumulative physical presence in Canada before the child’s birth or adoption. The days don’t need to be consecutive.
What This Means in Practice
- Second-generation-plus families: if your parent or even grandparent was Canadian but you were born abroad and previously told you didn’t qualify — reassess. The retroactive rule may cover you.
- Canadian expats planning families: if you were born abroad and expect to have children abroad, your time physically in Canada now matters. Keep records (school transcripts, tax records, travel history) that prove your 1,095 days.
- Proof of citizenship applications: the mechanism is a citizenship certificate application to IRCC — see the official IRCC page on the 2025 rule changes. Processing volumes surged after the law took effect, and wait times for certificates have grown accordingly.
What Bill C-3 Does Not Do
- It doesn’t grant citizenship to people with no Canadian parent in their line
- It doesn’t change naturalization rules for permanent residents (the 3-in-5-years residency path is unchanged)
- It doesn’t automatically issue documents — you still need to apply for a citizenship certificate to have proof
One related development to know: in mid-2026 IRCC reversed a batch of erroneous citizenship-surrender letters connected to C-3 implementation — if you received correspondence questioning your status, read our coverage of the IRCC Bill C-3 letter reversal.
Frequently Asked Questions
I was born abroad in 1995 to a Canadian father who was also born abroad. Am I a citizen?
Quite possibly, under the retroactive rule — you were born before December 15, 2025. Apply for proof of citizenship to confirm.
Do the 1,095 days need to be before the child’s birth?
Yes — the parent’s cumulative physical presence must be accumulated before the birth or adoption of the child.
Does this affect citizenship by naturalization?
No. It only changes citizenship by descent for people born outside Canada.
