Am I Canadian If My Grandparent Was Born in Canada?

Short answer: Very likely, yes. If your grandparent was born in Canada, and both your parent and you were born outside Canada before December 15, 2025, Bill C-3 generally makes you a Canadian citizen already. You do not apply to become Canadian; you apply to IRCC for proof of citizenship (a citizenship certificate) to have it recognized.

Why the answer changed

Before December 15, 2025, Canadian citizenship by descent stopped at the first generation born outside Canada. A grandchild born abroad to a parent who was also born abroad was usually cut off. Bill C-3 removed that limit for people born abroad before December 15, 2025, so the chain can now continue through your parent to you, and on to your own children born before that date.

Who this applies to

• The line can run through your mother or your father. Bill C-3 also addressed older rules that treated mothers and fathers differently.
• It must be a biological line. Citizenship by descent does not pass through adoption. Adopted children have a separate, more complex route called a grant of citizenship.
• The grandparent must not have formally renounced Canadian citizenship before your parent was born. Becoming a U.S. citizen did not usually count as renouncing; formal renunciation is a separate application to the Canadian government and is rare.
• Children born on or after December 15, 2025 are covered by a new rule: if you are Canadian by descent and your child is born abroad after that date, you must have spent at least 1,095 days in Canada before the birth to pass on citizenship.

How you prove it

The application shows the chain one generation at a time:

• your grandparent's Canadian birth record (or citizenship certificate, if they were naturalized);
• your parent's birth certificate, naming the Canadian grandparent;
• your own birth certificate, naming your parent;
• marriage or name-change records wherever a name changes between documents; and
• government photo identification for you.

We get certified copies of two records up front: your grandparent's Canadian birth record and your own birth certificate. Plain copies from the official source are enough for the rest.

What if your grandparent's Canadian birth record cannot be found?

This is common for births in the 1800s and early 1900s, and it is not the end of the claim. The application must explain why the record is unavailable, for example because civil registration did not yet exist where your grandparent was born, and support that with letters from churches or archives confirming that no record exists. It then relies on other evidence of the birth in Canada. In our experience, at least two Canadian sources, typically two Canadian census records showing your grandparent born in Canada, give a high chance of success. Less than that is possible but weaker.

Cost and timing

The IRCC fee is $75 CAD per applicant. IRCC's published processing time for proof of citizenship is about 34 months, with roughly 130,700 people waiting (IRCC figures, last updated October 9, 2026). Family members can file together in one package.

Frequently asked questions

Does it matter if my Canadian grandparent was my mother's parent rather than my father's?

No. The line can run through either parent.

My grandparent became a U.S. citizen. Does that break the chain?

Usually not. U.S. naturalization did not by itself end Canadian citizenship; formal renunciation is a separate application to Canada and was rare.

What if my grandparent's Canadian birth record is missing?

You explain why it is unavailable and rely on other evidence. In our experience, two Canadian sources, typically two census records, showing the birth in Canada give a high chance of success.
