Citizenship by Descent Calculator Canada 2026

Frequently asked questions

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

Yes. Bill C-3 (effective December 15, 2025) 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. The test applies to second-generation Canadians born abroad; first-generation Canadians are automatically citizens at birth.

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.

How does this calculator work?

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. First-generation (parent born in Canada or naturalized) grants automatic citizenship, second-generation requires the substantial connection test, and third-generation and beyond are generally not eligible through descent alone. It also identifies if you need to submit an application under Bill C-3's retroactive provisions.
