Canadian Citizenship by Descent in 2026: Who Qualifies Under Bill C-3 and How to Prove It

By the ImmigrationShop legal team · Last updated October 26, 2026

Short answer: If you were born outside Canada before December 15, 2025, and you have an unbroken line of Canadian citizenship running back through a parent, grandparent or earlier ancestor, you are most likely already a Canadian citizen. You don't need a test, an oath or a ceremony. What you need is proof: a Canadian citizenship certificate. That proof now takes about 34 months to get, and since June 2026 IRCC has been much stricter about which documents it accepts. Applying early, with the right records, matters more than ever.

This guide explains who qualifies, what changed in 2026, which documents IRCC now accepts, and how to apply without your file stalling.

What Bill C-3 changed

From 2009 until late 2025, Canadian citizenship by descent stopped at the first generation born abroad. If your Canadian parent was also born outside Canada, the line usually stopped with them, and you weren't Canadian. People in this group are often called "Lost Canadians."

In December 2023, the Ontario Superior Court of Justice declared that first-generation limit unconstitutional for many people. Parliament responded with Bill C-3, An Act to amend the Citizenship Act (2025):

• Introduced: June 5, 2025
• Royal Assent: November 20, 2025
• In force: December 15, 2025

The law did two things:

1. For people born before December 15, 2025: it removed the first-generation limit. If you would have been Canadian but for that limit (or similar outdated rules), you are now recognized as a citizen, back to your date of birth.
2. For children born on or after December 15, 2025: it created a new "substantial connection" test, explained below.

Anyone who was already a citizen before Bill C-3 remains a citizen.

Do you qualify? The quick test

If you were born before December 15, 2025

You are likely a Canadian citizen if you were born outside Canada to a parent who was a Canadian citizen when you were born. That includes a parent who only became Canadian because of Bill C-3. This is how the line now passes through several generations.

The key word is "unbroken." Each person in your line must have been a Canadian citizen when the next person was born. Having a Canadian ancestor isn't enough on its own; IRCC has said publicly that distant Canadian ancestry does not automatically make someone eligible.

Tip: If you have more than one Canadian ancestor, build your claim through the closest one. Every extra generation means more records to find and more places for a gap.

If your child was born on or after December 15, 2025

A child born abroad in the second generation or later is Canadian only if their Canadian parent spent at least 1,095 days (three years) physically in Canada before the child's birth. The same 1,095-day rule applies before an adoption, for adopted children applying for a direct grant of citizenship.

If you're a citizen by descent planning a family abroad, count your days in Canada now. Proving them later is much harder.

If you were adopted

People adopted outside Canada in the second generation or later may be eligible for a direct grant of citizenship for adopted people. That is a separate application from proof of citizenship, with its own rules.

"Automatic" doesn't mean "documented"

This is the part most people miss. Bill C-3 made you a citizen by law, but nobody will recognize it until you hold a citizenship certificate.

Without one, you cannot get a Canadian passport, and you may run into problems at the border, with employers, or when accessing benefits. IRCC's own guidance is clear: if you think Bill C-3 made you Canadian, you must apply for a certificate to confirm it.

What changed in June 2026: IRCC got stricter about documents

In June 2026, IRCC flagged about 100 citizenship certificates issued under Bill C-3 that may not have been backed by enough evidence. Some relied on records pulled from "open sources" such as genealogy websites. IRCC suspended those certificates and asked holders to return them, and some people were told their passports were no longer valid.

IRCC then reviewed roughly 6,500 Bill C-3 applications. It finished on June 30, 2026, and reported that:

• 33 of the flagged certificates were reinstated automatically.
• 67 cases, about 1% of certificates issued, were still under further review.
• Its own guidance on acceptable documents had been unclear, for officers as well as applicants.

Bill C-3 itself was not repealed, paused or reversed. But IRCC rewrote its document checklist (form CIT 0014) on June 17–18, 2026. Three changes matter most:

1. "Original" authority, not "appropriate" authority. Records must come from the body that created or keeps them: a civil registry, vital statistics office, provincial or state archive, or federal records office.
2. Third-party records alone are not enough. Printouts from Ancestry, FamilySearch, MyHeritage and similar sites are research tools, not proof. They can support a file, but they can't carry it.
3. Every generation must be proven. You must show parentage and Canadian citizenship for each person in the chain, not just for yourself and your Canadian ancestor.

What if a record no longer exists? IRCC now expects two things:

• a written explanation of why you can't provide it, and
• proof that you tried to get it, such as letters or emails with the issuing office, or an official "no record found" letter.

The lesson: A file that would have been approved in January 2026 may not be approved today. Build yours to the June 2026 standard from day one. It's far cheaper than fixing it after IRCC questions it, or after a certificate is suspended.

How long it takes: about 34 months

IRCC's processing time for proof of citizenship has climbed every month since Bill C-3 took effect:

About 130,700 people were waiting for a decision as of the October 2026 update. That was the first month the queue actually got shorter, falling from about 136,000.

IRCC's estimate is based on when your application arrives, so every month you wait adds people ahead of you. If you qualify, waiting rarely helps.

Can you skip the line? Urgent processing

IRCC may process a certificate faster if you need it, for example:

• to move your minor child to Canada (child born abroad with a Canadian parent)
• for work (to apply for a job or keep one) or for school in Canada
• to access social benefits such as a pension, health care or a Social Insurance Number
• to travel because of a death or serious illness in the family, when you can't get a passport from your other country
• to renounce another citizenship by a deadline
• to avoid harm or hardship, or in a case of statelessness

There is also a separate route for dual citizens. You can request urgent processing if you are also a citizen of a visa-exempt country (for example, the United States) and have proof of air travel to Canada within six months of applying.

Every urgent request needs a letter explaining the reason and supporting documents, such as a ticket with proof of payment, an employer or school letter, or a doctor's note. IRCC won't process incomplete applications, and even an approved urgent request comes with no guarantee of a decision in time.

How to apply for proof of Canadian citizenship: step by step

1. Map your chain. Write out each generation from your Canadian ancestor down to you, with birth dates and places. Mark where each person was born and whether they were a citizen when the next person was born.

2. Choose your anchor ancestor. Use the closest Canadian in your line. Confirm how they became Canadian: born in Canada, naturalized, or by descent.

3. Order certified records from the original authority. For each generation, you'll typically need:

• long-form birth certificates that name the parents (short forms often leave parents out)
• marriage certificates wherever a name changed
• proof of the anchor's Canadian citizenship, such as a Canadian birth record, naturalization record or citizenship certificate

4. Document any gaps. For anything you can't get, include your explanation and the proof that you tried.

5. Complete the application. That means the Application for a Citizenship Certificate (CIT 0001), checked against the Document Checklist (CIT 0014). Most people can apply online. Some must apply on paper.

6. Pay the government fee. It's CAD $75 per person. Each family member needs a separate application, though they can be filed together.

7. Request urgent processing, if you qualify. It's easiest to do this when you file, not afterwards.

8. Once the certificate arrives, apply for your Canadian passport.

Common mistakes that delay or sink applications

• Submitting genealogy-site printouts instead of certified records from the original authority
• Using short-form birth certificates that don't name the parents
• Missing marriage or name-change records, so names don't match from one generation to the next
• Skipping a generation and assuming IRCC will "connect the dots"
• Building the claim through a distant ancestor when a closer one was available
• Filing duplicate applications (for example, a paper urgent request and an online application for the same person)
• Assuming the 1,095-day rule applies to you when you were born before December 15, 2025. It doesn't; it only applies to people born on or after that date.

Frequently asked questions

Am I a Canadian citizen if my grandparent was Canadian?

Very likely, if you were born before December 15, 2025 and your parent was a Canadian citizen by descent when you were born. You still need a citizenship certificate to prove it.

Do I have to live in Canada or pass a test?

No. Citizenship by descent under Bill C-3 is recognized by law. There is no residency requirement, language test, citizenship test or oath. The 1,095-day test applies only to Canadian parents of children born on or after December 15, 2025.

Can I get a Canadian passport while my application is pending?

No. You need the citizenship certificate first.

Will I lose my U.S. (or other) citizenship?

Canada allows dual citizenship. Whether you keep your other citizenship depends on that country's laws. The United States generally permits dual nationality, but check your own country's rules.

Does Canadian citizenship mean I'll pay Canadian taxes?

Canada generally taxes people based on residency, not citizenship. Get advice from a cross-border tax professional before moving.

I'm Canadian under Bill C-3 but don't want to be. What can I do?

If the law made you a citizen automatically, you can apply to renounce your Canadian citizenship.

I applied before Bill C-3 took effect. Do I need to reapply?

No. IRCC is processing pending applications under the new rules. Do check whether your file meets the June 2026 document standard, and send any missing original-authority records through the IRCC web form.
