Claiming Canadian citizenship by descent for those born before 2009

If you were born outside Canada before 2009, and you have a Canadian parent, grandparent or earlier ancestor, you may already be a Canadian citizen.
Canada's new citizenship laws cover those who were previously impacted by the first generation limit (FGL) rule, which was first introduced in 2009.
Now found unconstitutional, Canada's FGL rule has been repealed and the country has enacted legislation to ensure that any individual who was denied Canadian citizenship due to the rule has now legally gained citizen status.
To fully attain Canadian citizenship and the rights that accompany it, you must submit a proof of citizenship application for a citizenship certificate.
You don't apply to become a Canadian citizen. You apply for the certificate that proves it.

Overview
On December 15, 2025, Bill C-3 (An Act to amend the Citizenship Act, 2025, c. 5) changed the first-generation limit to citizenship by descent.
Before that date, citizenship by descent generally stopped at the first generation born outside Canada. Bill C-3 removed that limit in many situations. Immigration, Refugees and Citizenship Canada (IRCC), the federal department that handles citizenship, now says that people born outside Canada before December 15, 2025 to a Canadian parent are in most cases automatically Canadian citizens.
This page explains who that covers, which older rules still matter if you were born before 2009, and how to get proof of your status. It doesn't cover people born on or after December 15, 2025, whose situation works differently
Who may be a Canadian citizen
You may already be a Canadian citizen if all of the following are true:
- You were born outside Canada;
- You were born before December 15, 2025; and
- You can trace an unbroken line of descent to an ancestor who was a Canadian citizen.
The number of generations no longer decides the outcome on its own. IRCC's application instructions now ask for documents proving the Canadian citizenship of "your parent, grandparent and parental ancestor."
The proof of citizenship application form sets out how to claim through a Canadian ancestor.You do not need to have lived in Canada. There's no language test, no residency requirement, no exam and no oath. Your ancestor didn't need to hold a Canadian passport or a citizenship certificate. What matters is whether they were a citizen under the law that applied at the time.
Some situations fall outside these rules. You're not automatically a citizen if your parent was granted Canadian citizenship after you were born. If you were born outside Canada and adopted by a Canadian parent, you're not automatically a citizen either, and you'd apply through a different process for adopted people.
What changed on December 15, 2025
Canada introduced the first-generation limit in 2009. It meant that a person born outside Canada to a Canadian parent was a citizen, but that person generally couldn't pass citizenship to their own child born outside Canada.
In December 2023, the Ontario Superior Court of Justice found key parts of that limit unconstitutional. Bill C-3 was Parliament's response.The instruction guide for the citizenship certificate application sets out who the change covers. A person born outside Canada to a Canadian parent before December 15, 2025 is automatically a Canadian citizen, effective from their date of birth or from the date they lost their citizenship.
That includes people who:lost citizenship on their 28th birthday under the former section 8 of the Citizenship Act, which Parliament repealed on April 17, 2009 were born between January 1, 1947 and December 15, 2025 to someone who was a Canadian citizen when they were born were born before January 1, 1947, or before April 1, 1949 in the case of Newfoundland and Labrador, to someone who became a Canadian citizen on that date were born before December 15, 2025 to someone who became a citizen through the 2009, 2015 or 2025 amendments to the Act
That last point matters more than it looks: If the changes made your parent a citizen, they can make you one too, even though your parent's status was only recognized recently.
Older rules that still matter if you were born before 2009
The first-generation limit no longer blocks claims. Other parts of Canada's citizenship history still shape what you'll need to prove.
If you were born outside Canada before February 15, 1977
Canada's older citizenship law treated mothers and fathers differently. A Canadian father could pass citizenship to a child born abroad in wedlock. A Canadian mother generally couldn't.
That distinction no longer decides your case. The Citizenship Act now says a person is a citizen if they were born outside Canada before February 15, 1977 to a parent who was a citizen at the time of the birth. The provision doesn't distinguish between mothers and fathers, and it doesn't turn on whether your parents were married.
If your family has a registration of birth abroad or a certificate of retention
Under the rules in force between January 1, 1947 and February 14, 1977, a birth outside Canada had to be registered, and some people had to take steps to keep their citizenship. Two documents came out of that system: the Certificate of Registration of Birth Abroad and the Certificate of Retention of Canadian Citizenship.
Both are still valid proof of Canadian citizenship today. If one is sitting in a family file, you may be holding your answer already. IRCC asks you to include it with your application if you have it.
If your parent became a citizen of another country before 1977
Canada's older law caused some people to lose their citizenship when they took another nationality. IRCC still asks about this on the application form, for you and for your parent.
Later amendments restored citizenship to many people who lost it this way, and the restoration runs from the date of the loss rather than from the date of the amendment. The Act sets out exceptions, including for people who formally renounced their citizenship. Whether your parent's line was restored depends on the facts, and it's worth reviewing with a lawyer before you apply.
If your family line reaches back before 1947
Before January 1, 1947, there was no Canadian citizenship as such. People born or naturalized in Canada were British subjects. Newfoundland and Labrador joined Confederation later, and April 1, 1949 is the equivalent date there.
The Act now includes a set of provisions covering people who fell through the gaps at those transitions, and their children born outside Canada. Applications in this group are handled on paper and need more supporting evidence than a straightforward parent-to-child claim.
Documents you'll need
Your application must be supported by authentic, reliable and verifiable documents for every generation you're claiming through. IRCC's standard is strict on two points. Documents must come from the original authority that created or keeps the record, such as a provincial vital statistics office or a civil registry. And your application can't be supported by third-party records alone.
For each Canadian ancestor in the chain, you'll usually provide one or more of:
- a provincial or territorial birth certificate
- a birth certificate from another country showing the parent-child relationship in that generation
- a Canadian citizenship or naturalization certificate
- a Certificate of Registration of Birth Abroad, or a Certificate of Retention of Canadian Citizenship
- a British naturalization certificate issued in Canada, Newfoundland or Labrador
- proof of British subject status or landed immigrant status in Canada before January 1, 1947, or before April 1, 1949 for Newfoundland and Labrador
You'll also need your own birth certificate showing your Canadian parent's name, two pieces of identification, and photos that meet IRCC's citizenship photo specifications. Documents in another language need a translation and an affidavit from the translator. IRCC doesn't accept translations done by family members.
If a record was destroyed or the office no longer holds it, you can't simply substitute a baptismal record or a school record. IRCC asks you to explain in writing why you can't get the official document, and to show evidence that you tried, such as correspondence with the issuing authority. Records like these can support an application, but they can't carry it alone.
Gathering the chain is where most applicants get stuck. A claim through a great-grandparent can require birth records across four generations, in two or more countries.
How to apply
You apply for a citizenship certificate through a proof of citizenship application, using form CIT 0001. The document checklist is form CIT 0014.
Most applicants will have to apply on paper, including applications from people born in Canada who've never held a certificate, and applications in the pre-1947 British subject categories. IRCC runs a short questionnaire on its website to tell you whether your situation qualifies.
Paper applications go to the Case Processing Centre in Sydney, Nova Scotia.
Choose your certificate format on the application. An electronic certificate arrives as a downloadable PDF and carries a number starting with X. A paper certificate is an 8½ by 11 inch document and carries a number starting with K. Both are valid proof, and you can hold only one.
Don't apply twice for the same request. If you've already applied on paper, IRCC won't process an online application for the same thing.
Processing takes multiple months with wait times fluctuating based on demand. You can check the current figure using IRCC's processing times tool. Urgent processing exists for a narrow set of situations and requires documented proof of the urgency.
After you receive your certificate
A citizenship certificate shows your name, date of birth, gender, unique client identifier, certificate number and the effective date of your citizenship. It doesn't carry a photo, and it isn't an identity document. Don't laminate it, because that makes it invalid.
The certificate is the document you use to apply for a Canadian passport. If you were born outside Canada, you need it before a passport application will go anywhere. People born in Canada can generally use a provincial or territorial birth certificate instead.
Citizenship cards, which IRCC stopped issuing in February 2012, remain valid proof.
What Canadian citizenship gives you
- The right to live, work and study anywhere in Canada, with no permit and no residency condition
- Access to International Experience Canada work opportunities (for you or your children)
- The right to vote in federal elections and to run for office
- Access to provincial health coverage once you become a resident of a province. Waiting periods differ by province.
- The ability to pass your status to your children
Canada allows dual citizenship. Becoming Canadian doesn't affect your American citizenship, or your citizenship of most other countries.
Canada taxes on residency rather than citizenship, which works differently from the United States system. Cross-border tax rules are complex, and you should speak with a cross-border tax professional about your own situation.
If you qualify, your relatives probably do too
Citizenship by descent runs through a family line, not through one person. If you're eligible through a particular ancestor, your siblings are almost certainly eligible through the same ancestor. So are your cousins, and in many cases their children.
The genealogical work happens once. A single set of records can support applications across an extended family, and applications for family members submitted together are processed together.
