Canadian Citizenship by Descent Documents: Complete Checklist

Your Canadian citizenship by descent application lives or dies on your documents. Missing a single piece, submitting a short-form birth certificate instead of long-form, or failing to translate a Quebec document properly will trigger a rejection and cost you months of processing time. This checklist covers exactly what you need, organized by generation, so you can submit once and get it right.

The core principle: proving the chain

Every citizenship by descent application is a proof exercise. You're showing IRCC an unbroken chain from you, through your parent, to your Canadian-citizen ancestor. Each link in that chain requires specific documents, and the format matters as much as the content.

The CIT 0001 form itself is straightforward—we've covered it line-by-line in our step-by-step form guide. But the 15–20 pages of supporting documents you attach are what IRCC actually scrutinizes.

Your documents (the applicant)

These prove your identity and your birth to a Canadian-citizen parent.

Birth certificate (long-form, government-issued)

You need the long-form or certified birth certificate issued by the vital statistics office in your birth state, province, or country. This version includes:

• Your full name
• Date and place of birth
• Both parents' full names
• Registration number and issuing authority

Hospital birth certificates, short-form "wallet cards," and souvenir certificates do not qualify. IRCC needs to see who your parents are.

If you were born in the United States, you order this from your birth state's vital records office. Turnaround ranges from 2 days (online expedited orders in states like Texas) to 8 weeks (New York City, we're looking at you).

If you were born outside Canada and the US, you'll need an official birth certificate from the civil registry in that country, plus a certified English or French translation if the original is in another language.

Government-issued photo ID (copy)

A clear, legible photocopy of your current:

• Passport (photo and signature pages), or
• Driver's license (both sides), or
• National identity card

IRCC uses this to confirm your current identity matches your birth certificate. If your name has changed since birth, see the section on name-change documents below.

Two identical photos

Passport-style photos taken within the last 6 months:

• 50 mm × 70 mm (approximately 2" × 2.75")
• White or light-coloured background
• Neutral expression, no glasses (unless medically required)
• Name and date of birth written on the back

The photo studio must stamp the back of one photo and complete the declaration on the back of the other. These are the same specs as a Canadian passport photo.

Your parent's documents (the connecting generation)

This is the person who transmitted citizenship to you—the one born outside Canada to a Canadian-citizen parent before December 15, 2025 (when Bill C-3 came into force and ended the first-generation limit).

Birth certificate (long-form)

Your parent's long-form birth certificate, showing:

• Their full name
• Date and place of birth
• Both of their parents' full names (i.e., your grandparents or great-grandparents)

This document connects you to the Canadian-born generation. If your parent was born in the US, order from their birth state. If born elsewhere, same rules apply: government-issued, long-form, with parents' names visible.

Marriage certificate or name-change documents (if applicable)

If your parent's surname on their birth certificate differs from the surname on your birth certificate (for example, your mother's maiden name vs. married name), you must prove the connection with:

• A marriage certificate (long-form, showing both spouses' full names), or
• A legal name-change certificate, or
• Divorce decree showing former and current names

IRCC will not assume a name change. You must document it.

Your Canadian ancestor's documents (the load-bearing generation)

This is the person born in Canada who is the source of your claim. Usually a grandparent or great-grandparent.

Canadian long-form birth certificate (the critical document)

This is the single most important document in your application. It must be:

• Long-form (also called "full" or "certified" birth certificate)
• Issued by a provincial or territorial vital statistics office
• Show the ancestor's full name, date and place of birth in Canada, and parents' names

Short-form certificates—common in Ontario and other provinces—show only the person's name and birth date, without parents' names. IRCC will reject your application if you submit a short-form certificate.

Ordering instructions vary by province:

• Ontario: Order from ServiceOntario online or in person. Long-form costs $45 CAD. Ships in 15–20 business days. See our detailed Ontario guide.
• Quebec: Order from Directeur de l'état civil. If the birth certificate is in French, you must include a certified translation by a member of a recognized translators' association (OTTIAQ, ATIO, CTINB, etc.) with the translator's affidavit. See our Quebec-specific guide.
• British Columbia: Order from Vital Statistics Agency online. $50 CAD. 4–6 weeks.
• Alberta, Saskatchewan, Manitoba: Faster turnaround (1–2 weeks), order online from provincial vital statistics.
• Maritime provinces: 2–4 weeks, order by mail or online depending on province.

If your Canadian ancestor was born before provincial registration systems were robust (pre-1920s in some provinces), you may need baptismal records or other church records. Contact an RCIC or Canadian immigration lawyer if you're in this situation.

Marriage certificate or name-change documents (if applicable)

If your Canadian ancestor's surname on their birth certificate differs from the surname on your parent's birth certificate, include:

• Marriage certificate (long-form)
• Legal name-change certificate
• Divorce decree

For example, if your grandmother was born Mary Smith in Ontario but your mother's birth certificate lists her as Mary Johnson, you need proof of that name change.

Additional documents for complex cases

Multiple name changes across generations

If more than one person in the chain changed names, document every single change. Chain them clearly: birth name → first marriage → second marriage → current name. Label each document in your application package.

Adoption

If you or anyone in the chain was adopted:

• Include the adoption order or decree
• IRCC may request additional documentation depending on the date and jurisdiction of the adoption

Citizenship transmission through adoptive parents follows different rules depending on when and where the adoption occurred. Consult an RCIC if adoption is part of your claim.

Parents not married at the time of your birth

For births before February 15, 1977, Canadian citizenship law treated children born outside Canada differently depending on whether the parents were married. You may need to provide:

• Proof that parents later married, or
• Statutory declarations regarding parentage, or
• Evidence of the Canadian parent's custody or guardianship

This is covered in detail in our Lost Canadians guide, as these scenarios were common among people excluded before Bill C-3.

Translation requirements

Any document not in English or French requires a certified translation by a member of a recognized translators' association:

• Association of Translators and Interpreters of Ontario (ATIO)
• Ordre des traducteurs, terminologues et interprètes agréés du Québec (OTTIAQ)
• Society of Translators and Interpreters of British Columbia (STIBC)
• Others listed on IRCC's website

The translator must include:

• A signed affidavit or declaration
• Their membership number and association
• A statement that the translation is accurate and complete

Submit both the original document and the certified translation. Do not submit only the translation.

What happens if you're missing something

IRCC will send you a procedural fairness letter or a request for additional documents. You'll typically have 30 to 60 days to respond. This adds 3–6 months to your processing time.

Common rejection triggers:

• Short-form birth certificate instead of long-form
• Missing parents' names on a birth certificate
• Undocumented name change
• Missing or improper translation
• Unsigned photos or wrong photo dimensions

We've written a detailed guide to common CIT 0001 rejection reasons if you want to see real examples.

How long to wait after submitting

Once your complete, correct application arrives at the IRCC processing centre in Sydney, Nova Scotia, you're looking at 9 to 12 months for processing under current timelines. We track this monthly in our processing time guide.

You can check your application status through your IRCC online account (if you created one) or by calling IRCC's client support centre. They won't have updates in the first 6–8 weeks—your file is in the intake queue.

Start with an eligibility check

Before you order long-form birth certificates from three provinces, spend two minutes confirming you're actually eligible under Bill C-3. Our free eligibility quiz at arryv.ai/check walks through your family tree and tells you whether you qualify through the grandparent pathway, great-grandparent pathway, or another route. If you qualify, we'll generate a personalized document checklist and help you gather everything IRCC needs—correctly, the first time.
