Citizenship by Descent Calculator Canada 2026

Check if you qualify for Canadian citizenship by descent under Bill C-3. First and second generation abroad, substantial connection test.

Key Takeaways

  • Bill C-3 (effective December 15, 2025) restored citizenship rights for many Canadians born abroad who lost status under the 2009 first-generation limit.
  • First-generation Canadians born abroad are automatically citizens at birth, regardless of when they were born.
  • Second-generation Canadians born abroad must prove their Canadian parent had a substantial connection to Canada (at least 1,095 days of physical presence before the child's birth).
  • Children of Crown servants (military, diplomats, federal employees) serving abroad are exempt from generational limits.

Canadian Citizenship by Descent — Bill C-3 Eligibility

Canadian citizenship by descent allows children born outside Canada to a Canadian parent to acquire citizenship automatically at birth. Bill C-3, which took effect on December 15, 2025, significantly expanded these rights by removing the previous first-generation limit that had left many "Lost Canadians" without citizenship since 2009.

How It Works

Enter your parent's citizenship information and your birth details to determine if you qualify for Canadian citizenship by descent. The calculator evaluates your generation classification, checks whether the substantial connection test applies, and identifies if you need to submit an application under the retroactive provisions.

Generation Classification

Under Bill C-3, your eligibility depends on which "generation born abroad" you fall into. First-generation (your parent was born in Canada or became a citizen through naturalization) grants automatic citizenship. Second-generation (your parent was also born abroad but was a citizen at birth) requires the substantial connection test. Third-generation and beyond are generally not eligible through descent alone.

Substantial Connection Test

For second-generation Canadians born abroad, the Canadian parent must demonstrate a substantial connection to Canada. The primary requirement is at least 1,095 days (3 years) of physical presence in Canada before the child's birth or adoption. This test ensures that citizenship by descent remains connected to genuine ties to Canada.

Key Facts

  • Bill C-3 took effect December 15, 2025, and applies retroactively to people born before that date.
  • The substantial connection test requires 1,095 days of the parent's physical presence in Canada before the child's birth.
  • Crown servants (Canadian Armed Forces, federal employees, provincial public servants) serving abroad are exempt from generational limits.
  • Adopted children are treated the same as biological children if the adoption was processed through the citizenship grant pathway.
  • People born between April 17, 2009, and December 14, 2025, to second-generation parents may need to apply to confirm their restored citizenship.

FAQ

Does Bill C-3 apply to me if I was born before 2025?

Yes. Bill C-3 is retroactive. If you were born abroad to a Canadian parent and previously lost or were denied citizenship under the 2009 first-generation limit, you may now be eligible. Those born between April 17, 2009, and December 14, 2025, may need to submit an application to IRCC to confirm their citizenship.

What counts as "substantial connection" to Canada?

The primary measure is physical presence — your Canadian parent must have spent at least 1,095 days (3 years) in Canada before your birth or adoption. IRCC may also consider other factors such as language, family ties, and tax filing history, but the 1,095-day threshold is the key requirement under Bill C-3.

My parent was a diplomat posted abroad. Am I eligible?

Yes. Children of Crown servants (Canadian Armed Forces members, federal public servants, provincial/territorial public servants) serving abroad are exempt from the generational limits. This means you qualify for citizenship by descent regardless of which generation you are.

I was adopted by a Canadian citizen. Do I qualify?

It depends on the adoption pathway. If your adoption was processed through the citizenship grant pathway (direct grant of citizenship), the same descent rules apply as for biological children. If the adoption was processed through the immigration pathway (permanent residency first), the descent rules do not apply — you would instead use the citizenship timeline calculator for the naturalization path.
