Canadian Citizenship by Descent FAQ: 30 Questions Answered (2026)

If you're exploring Canadian citizenship by descent after Bill C-3, you probably have questions. This FAQ answers the 30 most common questions about eligibility, the application process, dual citizenship, taxes, timelines, and what happens after you receive your certificate.

We've organized these answers based on real questions from Americans and others with Canadian ancestry who are navigating the new law.

Eligibility questions

Am I eligible for Canadian citizenship by descent under Bill C-3?

You're eligible if you were born outside Canada to a Canadian-citizen parent, even if that parent was also born outside Canada. Before December 15, 2025, the first-generation limit cut off citizenship for anyone whose Canadian parent was also born abroad. Bill C-3 eliminated that rule.

The most common pathway: your grandparent was born in Canada, your parent was born outside Canada (and is a Canadian citizen), and you were born outside Canada. You are now a Canadian citizen retroactively to your birth, and you can claim it by applying for a citizenship certificate.

For a detailed walkthrough of this scenario, read our grandparent pathway guide.

What if my parent never knew they were a Canadian citizen?

That doesn't matter. Citizenship by descent is automatic at birth. Your parent became a Canadian citizen the moment they were born, whether or not anyone applied for documentation. They don't need to apply for or activate their citizenship before you apply for yours.

You'll prove their citizenship through their birth certificate and your grandparent's Canadian birth certificate. IRCC will assess the chain of descent and recognize both your parent's and your citizenship in a single application.

Does my parent need to get a citizenship certificate first?

No. You can apply directly for your own certificate. IRCC will evaluate your parent's citizenship as part of your application. You'll need to submit your parent's birth certificate and proof that their parent (your grandparent) was Canadian-born.

If your parent wants their own certificate for travel or other purposes, they can apply separately, but it's not a prerequisite for your application.

What if my Canadian ancestor is my great-grandparent, not my grandparent?

This depends on when you and your parent were born. If your great-grandparent was born in Canada, your grandparent was born outside Canada, your parent was born outside Canada, and you were born outside Canada, the chain still holds—as long as you were born before April 17, 2009, when the first-generation limit took effect.

If you were born after December 15, 2025, your parent must meet the substantial connection test (1,095 days physically present in Canada before your birth). Read more in our great-grandparent guide.

I was adopted by a Canadian parent. Am I eligible?

Yes, if you were adopted before your 18th birthday and the adoption created a legal parent-child relationship recognized under Canadian law. Adoptions finalized in Canada, the U.S., and most other countries are recognized. You'll need to submit adoption records and proof of your adoptive parent's Canadian citizenship.

Adoption cases can be more complex. If you're unsure, consult an RCIC or Canadian immigration lawyer.

What if my grandparent left Canada as a child and never went back?

It doesn't matter. Canadian citizenship by birth is permanent. Your grandparent didn't lose it by living abroad, and they passed it to your parent at birth. You inherited it through your parent.

The only requirement is that your grandparent was born in Canada (or became a Canadian citizen through naturalization before your parent's birth).

Can I claim through a grandparent who naturalized as a Canadian citizen?

Yes, as long as your grandparent became a Canadian citizen before your parent was born. Citizenship by descent flows from a Canadian-citizen parent, whether that parent was born in Canada or naturalized.

You'll need proof of your grandparent's naturalization (citizenship certificate or naturalization certificate) and your parent's birth certificate showing they were born after that date.

Documents and application process

What documents do I need to apply?

You'll need:

• Your long-form birth certificate (showing parents' names)
• Your parent's long-form birth certificate (showing their parents' names)
• Your grandparent's long-form Canadian provincial birth certificate
• Two pieces of personal ID for yourself
• Two passport-style photos

If any documents are in French (especially Quebec birth certificates), you'll need a certified translation by a member of a recognized translators' association, with an affidavit. See our Quebec birth certificate guide for details.

What is a long-form birth certificate and where do I get one?

A long-form birth certificate (also called a certified copy of birth registration) includes your parents' names, not just your own name and birthdate. It's the official proof of parentage.

If your grandparent was born in Ontario, British Columbia, Alberta, or another Canadian province, you order it from that province's vital statistics office. Processing usually takes 2-6 weeks. We walk through this in our long-form birth certificate guide.

How do I fill out form CIT 0001?

Form CIT 0001 is the Application for a Citizenship Certificate (proof of citizenship). It's a 6-page form asking for your personal details, your parents' details, and your claim to citizenship.

We've published a line-by-line CIT 0001 guide that explains every section, common mistakes, and how to describe your descent pathway clearly.

Where do I mail my application?

Mail everything to the IRCC processing centre in Sydney, Nova Scotia:

Case Processing Centre – Sydney
Citizenship – Proof of Citizenship Unit
P.O. Box 10000
Sydney, NS B1P 7C1
Canada

Use tracked mail (USPS Priority Mail, FedEx, UPS) so you have proof of delivery. Don't use courier services that require a street address—IRCC uses a P.O. Box.

How much does it cost?

The application fee is $75 CAD per person. Pay by credit card, bank draft, or money order. If paying from the U.S., a money order in Canadian dollars from your bank works well.

There are no other mandatory government fees. Any other costs (photocopies, translations, postage, ordering birth certificates) vary by situation.

How long does processing take?

IRCC estimates 9-12 months for most citizenship certificate applications as of mid-2026. Some take longer, especially if documents are missing or require additional review.

You can check status online using your application number. Read more in our processing time guide.

Do I need a lawyer or immigration consultant?

No. The CIT 0001 application is straightforward if your lineage is clear and you have the right documents. Most people with a Canadian-born grandparent and complete birth records can apply on their own.

Consider consulting an RCIC or Canadian immigration lawyer if:

• Your lineage involves adoption, name changes, or missing records
• You're unsure whether you're a citizen
• Your application was rejected and you're appealing

Arryv is not a law firm, but we help you organize documents, fill out forms correctly, and avoid common rejection reasons. Learn more at /check.

What are the most common reasons applications get rejected?

The top reasons:

• Submitting a short-form birth certificate instead of long-form
• Missing or incomplete parent or grandparent birth certificates
• No certified translation for French documents
• Errors or omissions on form CIT 0001
• Insufficient proof of parent's or grandparent's citizenship

Our CIT 0001 rejection reasons guide covers each of these in detail.

Dual citizenship and legal questions

Does Canada allow dual citizenship?

Yes. Canada has allowed dual (and multiple) citizenship since 1977. You don't have to give up your current citizenship to become Canadian, and Canada won't require you to renounce.

Check your other country's rules. The U.S., U.K., Australia, and most Western countries also allow dual citizenship. A few countries (China, India, Japan, among others) do not.

Will the U.S. tax me if I claim Canadian citizenship?

If you're a U.S. citizen, the U.S. taxes you on worldwide income regardless of your other citizenships. Claiming Canadian citizenship doesn't change your U.S. tax obligations.

Canada taxes based on residency, not citizenship. If you live in the U.S., you won't owe Canadian income tax. If you move to Canada, you'll file in both countries and use the U.S.-Canada tax treaty to avoid double taxation.

Read our dual U.S.-Canadian citizenship tax guide for a full breakdown.

Can I vote in Canadian elections?

Yes. As a Canadian citizen, you can vote in federal elections even if you live abroad, as long as you've resided in Canada at some point or intend to in the future. Register with Elections Canada online.

You can also vote in provincial elections if you meet the residency requirements for that province (usually living there for a certain period).

Do I have to do military service?

No. Canada has no military conscription. The Canadian Armed Forces are all-volunteer.

Can my children inherit Canadian citizenship from me?

It depends on where and when they were born.

• If they were born before December 15, 2025, they are Canadian citizens by descent (the old first-generation limit no longer applies).
• If they were born on or after December 15, 2025 outside Canada, you must meet the substantial connection test: you need 1,095 cumulative days of physical presence in Canada before their birth.

If you've never lived in Canada and your child was born after December 15, 2025, they won't be Canadian citizens at birth. You'd need to move to Canada and accumulate 1,095 days, then have another child, or sponsor them for permanent residence.

Learn more in our substantial connection test guide.

What if I lose my citizenship certificate?

You can apply for a replacement using the same form (CIT 0001) and paying the $75 fee. Treat your certificate like a passport: store the original in a safe place and keep certified copies for travel or ID purposes.

You don't need the original certificate to apply for a passport. A certified copy or even a scanned copy submitted with your passport application usually works, though some offices may ask for verification.

Practical questions

What's the difference between a citizenship certificate and a passport?

A citizenship certificate is proof that you're a Canadian citizen. It's an 8.5" x 11" document. You can't travel with it.

A Canadian passport is a travel document that also proves citizenship. You need a citizenship certificate (or other proof of citizenship) to apply for a passport.

Most people apply for the certificate first, then use it to apply for a passport. Read our citizenship certificate vs. passport guide for details.

Can I apply for a Canadian passport right away?

Not until you receive your citizenship certificate. The passport application (form PPTC 153) requires you to submit proof of citizenship. Your certificate serves that purpose.

Once you have your certificate, you can apply for a passport by mail or in person at a Service Canada office or Canadian consulate. Processing takes 20-45 business days by mail, or 10 business days for in-person urgent service.

What can I do after I get my citizenship certificate?

You can:

• Apply for a Canadian passport
• Move to Canada and live, work, or study without any visa or permit
• Access Canadian healthcare (after meeting provincial residency requirements, usually 3 months)
• Sponsor family members for Canadian permanent residence (spouses, dependent children, parents in some cases)
• Vote in Canadian elections
• Apply for Canadian government jobs that require citizenship

Our guide on what to do after receiving your citizenship certificate covers next steps in detail.

Can I sponsor my spouse or children for Canadian permanent residence?

Yes, but only if you're living in Canada or plan to return to Canada when your sponsored family member becomes a permanent resident. Canadian citizens living abroad can sponsor spouses and dependent children, but you must prove your intent to move back.

The sponsorship process is separate from citizenship by descent. It involves a different application, fees (around $1,050 CAD for a spouse), and processing times of 12-18 months.

Consult an RCIC or immigration lawyer for sponsorship cases. Arryv focuses on citizenship certificate applications, not family sponsorship.

Do I need to live in Canada after I become a citizen?

No. Citizenship has no residency requirement once you have it. You can live anywhere in the world and remain a Canadian citizen for life. You won't lose your citizenship by living abroad.

This is different from permanent residence, which requires you to spend at least 730 days in Canada in every five-year period.

What if my documents have different name spellings?

Minor variations (middle name vs. middle initial, hyphenated surnames, accented characters) are common and usually fine. Include a brief letter of explanation with your application noting the discrepancy and explaining that the documents refer to the same person.

If there's a legal name change (marriage, court order, etc.), include the official name change document (marriage certificate, court order, deed poll).

Can I apply if my parent or grandparent is deceased?

Yes. Citizenship by descent doesn't require your parent or grandparent to be alive. You just need their birth certificates and proof of their Canadian citizenship. If your grandparent is deceased, order their birth certificate from the province where they were born—vital statistics offices issue certificates for deceased individuals to family members.

What if I can't find my grandparent's birth certificate?

If your grandparent was born in Canada, their birth was registered with the province. Contact the vital statistics office in the province where they were born and request a copy. You'll need some identifying information (full name, approximate birth date, parents' names if known).

If the birth was never registered (rare but possible for very old records), you may need alternative proof: baptismal records, census records, immigration records showing they were born in Canada. Consult an RCIC or immigration lawyer for guidance on complex cases.

I was born before 1947. Am I still eligible?

Possibly, but it depends on the specific details of your lineage and the laws in effect when you were born. Canadian citizenship as a distinct legal status was created on January 1, 1947. Before that, Canadians were British subjects.

Bill C-3 expanded eligibility for many people born before 1947 (often called "Lost Canadians"), but each case is unique. Read our Lost Canadians and Bill C-3 guide or consult an immigration lawyer.

Timeline and next steps

What happens after I mail my application?

IRCC receives your application, opens it, and checks that the fee and documents are included. You'll receive an acknowledgement letter (by mail or email) with an application number. Use that number to check status online.

IRCC reviews your documents, verifies your lineage, and processes your application. If anything is missing or unclear, they'll send a request for additional information. If everything is in order, they'll approve your application and mail your citizenship certificate.

Can I travel to Canada while my application is processing?

Yes, using your current passport and citizenship. If you're American, you don't need a visa to visit Canada for up to six months. Your pending citizenship application doesn't affect your ability to enter Canada as a visitor.

You can't enter as a Canadian citizen or apply for a Canadian passport until you have your citizenship certificate.

What if my application is rejected?

You'll receive a letter explaining why. Common reasons include missing documents, incorrect form answers, or failure to prove the chain of descent. In most cases, you can correct the issue and reapply.

If you believe the rejection was incorrect, you can request a review or appeal through the Federal Court. Consult a Canadian immigration lawyer if you're considering an appeal.
