How to Fill Out the CIT 0001 Application
A complete, step-by-step guide to filling out Canada's Proof of Citizenship application form in 2026. Whether you're claiming citizenship by descent under Bill C-3 or replacing a lost certificate, this guide walks you through every section.
What Is the CIT 0001 Form?
The CIT 0001 is the official application form used by Immigration, Refugees and Citizenship Canada (IRCC) for issuing a Proof of Canadian Citizenship certificate. This is the document you need if you are a Canadian citizen but do not currently hold a citizenship certificate or Canadian passport.
For Americans claiming citizenship by descent — meaning you were born outside Canada to a Canadian-born parent or ancestor — the CIT 0001 is the form you will submit to prove your citizenship. Under Bill C-3, the former first-generation limit has been removed, so even if your grandparent or great-grandparent was the one born in Canada, you may now qualify.
The CIT 0001 form is not an application for citizenship — it is an application to prove citizenship you already hold. This is an important distinction: if you qualify under Bill C-3, you are already legally a Canadian citizen. The CIT 0001 simply gets you the official certificate that proves it.
Before You Start: What You'll Need
Gather all of these documents before you begin filling out the form. Having everything ready will make the process much smoother.
- Your birth certificate — A certified copy of your own birth certificate showing your parents' names.
- Canadian ancestor's birth certificate — A long-form Canadian birth certificate for your parent (or grandparent/great-grandparent if claiming under Bill C-3) that shows their parents' names. Must be issued by a Canadian provincial vital statistics office. See our document ordering guide for how to order one.
- Marriage certificates — If names changed through marriage between any generation in the chain, you will need marriage certificates to show the name-change link.
- Intermediate birth certificates — For multi-generational claims (grandparent, great-grandparent), you will need birth certificates for each person in the chain between you and the ancestor born in Canada.
- Two passport-style photos — Meeting Canadian passport photo specifications (50mm x 70mm, white background, taken within the last 6 months).
- Current government-issued photo ID — A copy of your passport, driver's license, or state ID.
- $75 CAD filing fee — Payable online via the IRCC portal or by cheque/money order if submitting by mail.
Section-by-Section Walkthrough
Section A: Applicant Information
This section collects your personal details. Fill in every field exactly as it appears on your official documents.
- Full legal name: Enter your name exactly as it appears on your birth certificate. If your name has changed (through marriage or legal name change), use your current legal name and include documentation of the name change.
- Date and place of birth: Enter the city, state/province, and country where you were born. This must match your birth certificate exactly.
- Gender: Select as it appears on your current ID. Canada allows M, F, or X designations.
- Current mailing address: This is where IRCC will mail your citizenship certificate. Provide a stable address where you will be able to receive mail for the next 6 to 12 months. If you use a US address, make sure to include the country.
- Email and phone: IRCC may contact you if they need additional information. Provide contact details you actively monitor.
- Previous citizenship applications: Indicate whether you have ever previously applied for a proof of Canadian citizenship or been issued a citizenship certificate. If you were previously denied under the old first-generation limit, note this — Bill C-3 now makes you eligible.
Section B: Citizenship Information (Family Chain)
This is the most critical section of the form. Here you establish the chain of citizenship from you back to the ancestor who was born in (or naturalized in) Canada.
- Parent's information: Enter the full legal name, date of birth, place of birth, and citizenship status of the parent through whom you are claiming Canadian citizenship. If that parent was born in Canada, this establishes a direct one-generation chain. Include their Canadian birth certificate number if available.
- Grandparent's information (if applicable): If your parent was not born in Canada but your grandparent was, you will need to document both generations. Enter your grandparent's details and provide birth certificates for both your parent and grandparent. Under Bill C-3, this multi-generational claim is now valid.
- Great-grandparent's information (if applicable): For even longer chains, document each generation with full names, birth details, and supporting vital records. Each link in the chain must be supported by a birth certificate showing the parent-child relationship.
- How your ancestor became Canadian: Indicate whether your Canadian ancestor acquired citizenship by birth in Canada, by naturalization, or through another provision of Canadian law. For most Americans applying under Bill C-3, the ancestor was simply born in Canada.
Signatures & Declaration
The final section requires your signature and a declaration that all information provided is truthful and complete.
- Applicant signature: Sign and date the form. If submitting online through the IRCC portal, an electronic signature is accepted. If submitting by mail, the form must have an original wet-ink signature.
- Declaration of truth: By signing, you are declaring under penalty of law that all information in the application is true and complete. Providing false information on a citizenship application is a criminal offense under the Canadian Citizenship Act and can result in denial, revocation of citizenship, or criminal prosecution.
- Guarantor (if required): Depending on your circumstances, IRCC may require a guarantor — a Canadian citizen who has known you for at least 2 years and can vouch for your identity. The guarantor must sign a section of the form and provide their citizenship certificate number. Not all applications require a guarantor; this depends on the specific instructions provided by IRCC at the time of your application.
Common Mistakes to Avoid
- Using the short-form birth certificate: IRCC requires the long-form birth certificate that includes parents' names. Short-form or wallet-size certificates that only show your name and birth date will be rejected. This is the single most common reason for application returns.
- Name mismatches between documents: If your mother's maiden name appears on your birth certificate but her married name appears on other documents, you need a marriage certificate to bridge the gap. Every name change in the chain must be documented.
- Missing a generation in the chain: For multi-generational claims, you must document every link from you to the ancestor born in Canada. Skipping even one generation will result in your application being returned.
- Incorrect photo specifications: Photos must be 50mm x 70mm with a white background. Photos that are the wrong size, have shadows, or show the applicant wearing sunglasses or hats (except for religious headwear) will be rejected.
- Forgetting to sign the form: It sounds obvious, but unsigned applications are returned without processing. Double-check before you submit.
- Sending photocopies instead of certified copies: IRCC requires certified true copies of all supporting documents, or original documents. A plain photocopy is not acceptable.
Fee Payment ($75 CAD)
The government filing fee for a CIT 0001 application is $75 CAD per adult applicant. This fee is paid directly to IRCC — it is separate from any MaplePass service fees.
If submitting online through the IRCC portal, you can pay by credit card (Visa, Mastercard, or American Express). If submitting by mail, include a cheque or money order payable to "Receiver General for Canada" for $75 CAD. Do not send cash. Personal cheques drawn on a US bank may not be accepted — use a Canadian-dollar money order from your bank or a postal money order instead.
There is no fee for children under 18 who are included on a parent's application. However, if you are applying for separate certificates for multiple family members, each adult application requires its own $75 CAD fee.
How to Submit Your Application
Option 1: Online (Recommended)
Submit through the IRCC online portal at ircc.canada.ca. You will need to create an IRCC online account, upload your completed form and scanned supporting documents, and pay the $75 CAD fee by credit card. Online applications generally receive faster processing and you can track your application status online.
Option 2: By Mail
Mail your completed CIT 0001 form, supporting documents (certified copies), photos, fee payment, and a return envelope to the IRCC Case Processing Centre in Sydney, Nova Scotia. Use a tracked mailing service and keep copies of everything you send. Allow extra time for international mail from the US.

Processing Time
As of 2026, IRCC processing times for proof of citizenship applications range from 5 to 12 months, depending on the complexity of your case and current application volume. The surge in applications following Bill C-3 has increased wait times somewhat.
Simple cases (one-generation, parent born in Canada with straightforward documentation) tend to be processed faster. Multi-generational claims or cases with name discrepancies may take longer as IRCC verifies the full chain of citizenship.
You can check the current posted processing times on the IRCC processing times page. If you submitted online, you can track your application status through your IRCC account. If you submitted by mail, allow at least 4 weeks for your application to be received and entered into the system before checking status.
