Canadian Citizenship by Descent

Who does citizenship by descent apply to?

If you were born outside Canada and have a Canadian ancestor in your direct family line (a parent, grandparent, great-grandparent, or beyond) citizenship by descent may apply to you. After Bill C-3, citizenship can now pass down through multiple generations. This often includes people born in the United States, United Kingdom, or elsewhere; people whose family emigrated from Canada decades ago; and people who only recently discovered their Canadian ancestry, many of whom have never held a Canadian passport or set foot in Canada. This also includes newly born children, though for babies born on or after December 15, 2025, the Canadian parent may need to meet a physical presence requirement in certain cases (see Family & Children below).

Am I automatically a citizen, or do I need to apply?

If you qualify for citizenship by descent, you are already a Canadian citizen by operation of law. You do not apply for citizenship in the way a naturalized applicant would. What you apply for is a citizenship certificate, which is official proof of the citizenship you already hold. The certificate is required before you can apply for a Canadian passport or otherwise document your status.

Does time spent in Canada at any age count toward the 1,095 days?

Yes. Any day you were physically present in Canada counts toward the 1,095 cumulative days, including time spent as a child, student, visitor, temporary resident, or worker. Days do not need to be consecutive. Examples of strong evidence may include tax returns, school records, employment records, leases, and passport stamps from any period of your life.

What was the first-generation limit, and has it been removed?

Before Bill C-3, Canadian citizenship by descent was generally limited to the first generation born outside Canada. Bill C-3 removed that limit for many people born or adopted before December 15, 2025. For people born or adopted on or after that date, citizenship can still pass beyond the first generation only if the Canadian parent meets the 1,095-day physical presence requirement.

What documents do I need to apply for a citizenship certificate?

The required documents depend on your family line, but you usually need your completed application, proof of identity, citizenship photos, your birth certificate, and the Canadian parent’s proof of citizenship. In descent cases, you may also need birth certificates for each generation in the chain, marriage certificates or other name-change records, and certified translations where needed. A cover letter is optional but can help explain the chain of descent.

How long does the application process take?

As of early 2026, IRCC processing times for citizenship certificates are approximately 10 to 12 months from the date of receipt. Processing times fluctuate and are expected to change as application volumes increase following Bill C-3. IRCC publishes updated estimates on its website.

Is there a deadline to apply?

No. If you qualify for citizenship by descent, your citizenship exists from the moment of your birth. There is no deadline to apply for proof. You can apply at any time.

Can I pass Canadian citizenship to my children?

It depends on when your child was born. If your child was born before December 15, 2025, they may qualify under the retroactive rules in Bill C-3. If your child was born on or after December 15, 2025, citizenship beyond the first generation generally requires the Canadian parent born or adopted abroad to have been physically present in Canada for at least 1,095 cumulative days before the child’s birth or adoption.

What is the 1,095-day physical presence requirement?

This is the substantial connection test under Bill C-3 for children born or adopted abroad on or after December 15, 2025. It requires the Canadian parent who was born or adopted abroad to have at least 1,095 cumulative days of physical presence in Canada before the child’s birth or adoption. The days do not need to be consecutive, and time in Canada at any age can count.

Does getting Canadian citizenship create a tax obligation?

“Canadian tax obligations are based on residency, not citizenship. Simply obtaining Canadian citizenship does not, by itself, create a Canadian tax‑filing requirement if you continue to live outside Canada and are not a Canadian tax resident, consistent with CRA guidance. The United States, in contrast, taxes its citizens on worldwide income regardless of residence.

If you open Canadian financial accounts, you may trigger foreign‑account reporting rules in your home country (for example, U.S. FBAR/FATCA), even though you still do not owe Canadian tax solely because of citizenship. Given the complexity of cross‑border tax rules and the importance of your specific circumstances, we recommend consulting a qualified cross‑border tax professional before making decisions based on tax consequences.

What if I was adopted by a Canadian citizen?

Adoption is a distinct route from citizenship by descent. Children adopted outside Canada by a Canadian citizen may be eligible for a direct grant of citizenship under section 5.1 of the Citizenship Act, which is application‑based, not automatic, and requires the adoption to be in the child’s best interests, create a genuine parent‑child relationship, and comply with the laws of the place of adoption and the adopting parent’s country of residence.

For adoptions occurring on or after December 15, 2025, the adoptive parent who was themselves born or adopted abroad must meet the 1,095‑day physical‑presence requirement in Canada before the adoption, mirroring the substantial‑connection test for citizenship by descent.

What if my parent is deceased and never claimed Canadian citizenship?

Your parent's citizenship exists whether or not they ever applied for proof, held a Canadian passport, or knew they were Canadian. The death of a parent does not break the chain of descent. Bill C-3 was designed to provide relief in cases where a parent or grandparent died before the law came into force, so that surviving descendants are not penalized for circumstances outside their control. The specific application depends on the family situation.

Do I need a lawyer or immigration consultant to apply?

For straightforward cases, such as when your parent was born in Canada, documentation is clear, and there are no name discrepancies, many people successfully apply on their own. For more complex situations involving unclear ancestry chains, missing or destroyed records, prior refusals, pre-1947 maternal line issues, or the substantial connection test, professional guidance can help you navigate the process and avoid delays or refusals.
