Proof of Citizenship · The plain-English guide
Canadian citizenship by descent, explained.
A plain-English walk through Bill C-3, how generations are counted, what documents you'll need to prove your line of descent, and the five steps to getting your citizenship certificate recognized by IRCC.
First, a distinction
What you're actually applying for.
Most people call it Canadian citizenship by descent. That's the phrase you'll see in the news, on Facebook and other social media groups, and in most of the articles about Bill C-3. It's the phrase we use too, because it's what people search for.
But technically, it's something slightly different — and the distinction matters.
The key point
If you qualify, you're already a Canadian citizen. You've been one since birth. You're not applying to become Canadian — you're asking IRCC to recognize and document that you already are.
The official process is called Proof of Citizenship. The form is CIT 0001. And what IRCC issues when your application is approved is a Canadian Citizenship Certificate — the document that proves the citizenship you've always had.
This distinction isn't just semantic. It changes how you frame your application, what you need to prove, and how you describe yourself on forms. You're not a citizenship applicant. You're an existing citizen applying for recognition.
The framework
How generations are counted.
The single most important thing to understand before you check your eligibility. Everything else — which documents you'll need, how complex your application will be, what you can prove — flows from this.
Gen 0 — The anchor
Canadian citizen
Every chain of descent starts here. This is your Canadian-born ancestor — parent, grandparent, great-grandparent, or further back. Gen 0 is not counted as a generation in the generational math. They're the origin point.
Generation 1
Their child
The first person in the chain born outside Canada. Under both the old rule and the new rule, this person has always been Canadian by descent.
Generation 2
Their grandchild
This is where the old rule cut the line. Before Bill C-3, Generation 2 was not automatically Canadian under the first-generation limit. Bill C-3 changes that.
Generation 3
Their great-grandchild
Also previously cut off. Also now eligible under Bill C-3, with citizenship restored retroactively for anyone born before December 15, 2025.
Generation 4+
And further back
There's no cap on how far back the chain can go — only a documentation challenge. Every link must be provable through official records.
The key detail
Generation 1 is not the first Canadian in your family — it's the first person in your chain who was born outside Canada to a Canadian citizen. The Canadian-born ancestor at the top of the chain isn't counted as a generation at all. They're Gen 0, the anchor.
Who qualifies
Does any of this sound like you?
Most applicants under Bill C-3 fall into one of four common situations. Each has its own wrinkles, but the underlying process is the same.
Most common path
My grandparent was Canadian
A Canadian-born grandparent, a parent born outside Canada, and you. The most straightforward scenario to document, with one anchor record and a clean two-generation chain.
Deeper ancestry
My Canadian ancestor goes back further
Great-grandparent, great-great-grandparent, or beyond. Bill C-3 removed the generational cap, but each additional generation means more documents to find and more chances for the chain to break.
What makes this different
Section 9 of the CIT 0001 form requires an extra sheet for each generation beyond great-grandparent. You'll need to prove each link in the chain individually.
Immigration waves
My Canadian roots are in Quebec
Roughly one million French Canadians left Quebec for New England between 1840 and 1930, leaving millions of American descendants. Other waves include the Acadians, Maritime migrations, and Black Loyalists. Each has its own archives, records, and conventions.
What makes this different
Quebec didn't start issuing civil birth certificates until 1926. Before that, parish baptismal records (held at BAnQ) serve as birth records. Names were often anglicized upon immigration.
Lost Canadians
I'm a "Lost Canadian"
Before Bill C-3, the first-generation limit excluded many eligible descendants — people the media and advocates came to call "Lost Canadians." If you were one of them and were born before December 15, 2025, the new law restores your citizenship retroactively. You're automatically Canadian now — you just need to apply for proof.
Complex situations — adoption, contested parentage, surrogacy, or other unusual legal circumstances — fall outside our scope. In those cases, we recommend consulting an immigration attorney.
What you'll need
Every application is built on a chain of documents.
To prove your line of descent, IRCC needs to see every link — from your Canadian-born ancestor down to you. Here's what that chain typically includes.
For each ancestor
Birth certificates
Long-form, naming both parents, issued by the appropriate provincial, territorial, or national authority. Every generation in the chain needs one.
Where surnames change
Marriage certificates
Required to connect maiden names to married names across generations. Without them, the chain can break even when all the birth certificates exist.
For your Canadian anchor
Proof of Canadian citizenship
A provincial birth certificate, naturalization record, or certified parish baptism record for older Quebec lineages. This is the document that anchors the entire application to Canada.
For you
Identity documents
Two pieces of valid ID — such as a passport, driver's license, or health insurance card — with at least one showing your photo. Plus two citizenship photos meeting IRCC specifications.
If documents aren't in English or French
Translations
Any document not already in English or French needs a translation. If the translator isn't certified in Canada, the translation must be accompanied by a notarized affidavit from the translator attesting to its accuracy. Quebec records in French are fine as-is.
Where gaps exist
Supporting evidence
Census records, death certificates, property deeds, naturalization papers, or sworn affidavits can help fill missing or unclear links when primary records are unavailable.

Open the Hub →The process
Five steps, start to finish.
The shape of the process is the same for every applicant. What varies is how much time you spend on each step — some lines take weeks to document, others take months.
01
Determine your eligibility
Identify your Canadian-born ancestor and map out the chain of descent from them down to you. Confirm that every generation in between can be traced.
02
Gather your documents
Request birth and marriage certificates for each generation in the chain, plus proof of your Canadian anchor's citizenship. This is where most applicants spend the majority of their time — archive response times range from days to months.
03
Complete the application
Fill out CIT 0001, the Application for a Citizenship Certificate. Write your cover letter. Prepare a generational summary showing how your documents connect the chain. Get two citizenship photos taken to IRCC specifications.
04
Assemble and mail
Organize your packet in the order IRCC expects, pay the application fee online through IRCC's portal, and mail your complete application to the correct address on the CIT0014 form (checklist). Tracking is strongly recommended.
05
Wait for your certificate
IRCC reviews the application, verifies the chain of descent, and issues your Canadian Citizenship Certificate. You may receive requests for additional documentation along the way. Processing times vary and are currently lengthening as submissions accelerate.
Time and cost
How long and how much.
The honest answer: it depends on your line. A straightforward grandparent application can take a few weeks and cost around $300. A seven-generation Quebec line can take months and cost well over $700. Here's what to plan for.
Your time investment
How long it takes
Gathering documents
2–12 weeks
Depends on how many generations, where records live, and archive response times.
Completing the application
A few days
Form, cover letter, generational summary, photos, and assembly.
IRCC processing
4–10 months
Currently lengthening as Bill C-3 applications accelerate.
Out-of-pocket expenses
How much it costs
IRCC application fee
$75 CAD
Paid online through IRCC's portal. One fee per adult applicant; free for minors.
Birth and marriage certificates
$15–$45 each
Varies by province, state, or country. Budget for one per generation, plus marriage certificates where surnames change.
Certified archive records
$100–$400
For older pre-civil-registration records — BAnQ parish records, diocese-issued baptism certificates, and similar. Often the single largest cost for Quebec and other historic lineages.
Translation (if needed)
$25+ per page
For documents not already in English or French.
Mailing with tracking
$15–$50
USPS or courier, depending on how fast and how protected you want it.
A note on the real cost
A straightforward grandparent-line application typically runs $300 to $400 total. A multi-generation application involving older archival records — especially Quebec parish records — can easily run $600 to $800 or more. The IRCC application fee itself is small; it's the research and record requests around it that add up.
The Resource Hub costs $39, one time. A session with a guide ranges from $50 to $450 depending on the scope. These are optional — everything you need to file is publicly available through IRCC and the archives themselves.
