You may already be Canadian—especially after the December 2025 changes.

01

Why status comes before an application

If you acquired citizenship at birth or received it through a legislative change, you should not apply for an adult grant. A citizenship certificate is commonly used to establish proof, and the official status checker is the safest starting point.

The analysis depends on birth dates, where each generation was born or naturalized, parentage, adoption and sometimes historic law. Do not decide status from a family story alone.

02

People born abroad before 15 December 2025

Legislative changes that took effect on December 15, 2025 restored or conferred citizenship on many people affected by the former first-generation limit and historic citizenship-loss rules. Individual exceptions and evidence requirements still apply.

A person affected by the change generally seeks proof through the citizenship-certificate process rather than applying for a discretionary grant.

03

People born abroad on or after 15 December 2025

When the Canadian parent was also born abroad, that parent generally must demonstrate at least 1,095 cumulative days physically present in Canada before the child’s birth to transmit citizenship. The days do not have to be consecutive.

A Canadian parent born in Canada or naturalized before the child’s birth can generally transmit citizenship without this additional substantial-connection test, subject to the complete statutory rules.

04

International adoption follows separate rules

Adoption by a Canadian does not automatically make the child a citizen in every case. Families may use a direct citizenship route or immigration followed by citizenship. Substantial-connection rules can apply when the Canadian adoptive parent was also born or adopted abroad.

Adoption validity, the child’s best interests and the absence of an adoption arranged mainly to obtain status are important parts of the process.

05

Build the family and presence evidence

IRCC may need long-form birth certificates, citizenship certificates, naturalization records, adoption records and evidence of the Canadian parent’s presence in Canada. Names, dates and parent-child links must line up across generations.

• Map every generation with dates and places of birth.
• Identify when each Canadian parent became a citizen.
• For the 1,095-day test, gather objective Canadian presence records.
• Use IRCC’s application package for the exact proof route.
• Seek qualified advice if parentage, adoption or historic loss rules are disputed.
