Proof of Canadian Citizenship: Certificate Guide 2026

A citizenship certificate does not make you a citizen. It confirms citizenship you already have, for example by birth outside Canada to a Canadian parent. You use it to apply for a Canadian passport, a pension, a social insurance number or a job. It is not a travel document and it does not prove your identity.

If you were born in Canada, a provincial or territorial birth certificate is usually enough proof, although you may still apply for a certificate. If you became a citizen through a grant (naturalization), you receive a certificate after the ceremony and do not need to apply for one.

   Bill C-3 takes effect

   An Act to amend the Citizenship Act (2025) changed the limit and, as IRCC puts it, removed it in some situations. Anyone who was already a citizen stays a citizen.

How IRCC counts generations: a Canadian citizen is someone born in Canada or granted citizenship. The first generation is a person born or adopted outside Canada to that citizen. A person born outside Canada to a first-generation parent is the second generation.

The 1,095 days are cumulative and have no time window: any days your parent spent in Canada before your birth count. The rule is in subsection 3(3) of the Citizenship Act. If both your parents are Canadian, it is enough for one of them to meet it. It does not apply if your parent was a Crown servant at the time of your birth (employed outside Canada in or with the Canadian Armed Forces, the federal public administration or the public service of a province, and not locally engaged), or if one of your grandparents was a Crown servant when your parent was born or adopted.

Adopted people: a person born and adopted outside Canada in the second generation or later is likely eligible for a direct grant of citizenship for adopted persons. For adoptions on or after December 15, 2025, the Canadian parent needs 1,095 days in Canada before the adoption.

If your parent does not meet the 1,095-day rule, you are not a citizen by descent. IRCC explains that you can become a permanent resident and later apply for a grant. A child born on or after December 15, 2025 who would otherwise be stateless can apply for a grant as a stateless person under subsection 5(5), which requires being under 23, having always been stateless and having 1,095 days in Canada in the 4 years before applying.

If you applied under the interim measure, IRCC processes your application under the new rules and you do not need to reapply. If the changes made you a citizen and you do not want to be one, you can apply to renounce with fewer requirements than usual, and IRCC charges no fee in that case.

You must prove the parent-child link and Canadian citizenship for every generation in your claim: your Canadian parent and, where relevant, your grandparent and earlier ancestors. IRCC requires authentic, reliable and verifiable documents issued by the original authority, such as a civil registry or vital statistics office. Third-party records alone are not enough.

• Birth recordsA provincial or territorial birth certificate, or a foreign birth certificate showing the parent-child relationship in each generation
• Citizenship recordsA Canadian citizenship or naturalization certificate, a Certificate of Registration of Birth Abroad or a Certificate of Retention of Canadian Citizenship
• If a birth certificate is missingOther original-authority records, such as a hospital birth record, a record from the physician or midwife, a baptismal record made soon after birth, census records or a boat manifest
• Parent's 1,095 days (births on or after December 15, 2025)Form CIT 0555 with proof such as T4 slips, school transcripts, passports or entry and exit records, leases or mortgages, government records, or affidavits
• Crown servant exceptionAn employer letter with the parent's or grandparent's name, positions, dates and the transfer abroad
• TranslationsDocuments not in English or French need a translation and the translator's affidavit. IRCC does not accept translations by family members.

If you cannot get an official document, explain in writing why and include proof that you tried, such as emails with the issuing authority. IRCC considers everything you send.

1. 1

   Check whether you can apply online

   IRCC's questions on its how-to-apply page give the answer for your case. In general, online applications are open to people born on or after February 15, 1977 who were naturalized on or after April 17, 2009 or were born abroad to a parent born in Canada on or after February 15, 1977 or naturalized on or after April 17, 2009. People born in Canada, replacements, updates, guardians applying for minors, 4 or more children and cases with unknown family details go on paper.

2. 2

   Prepare and submit

   Online, you have 60 days to submit after you start, and you pay by credit or Canadian debit card. On paper, send clear colour copies, the forms and the fee receipt. A parent can apply online for up to 3 children at once if the reason is the same for each.

3. 3

   Receive the acknowledgement of receipt (AOR)

   After IRCC confirms the application is complete, you get an AOR and your unique client identifier (UCI). Incomplete applications are returned.

4. 4

   Answer requests

   Complex files may need more information or time. IRCC's quality assurance program randomly selects some applications for an interview and may ask for more documents, up to DNA evidence of parentage.

5. 5

   Receive the decision

   If you are a citizen, you get an e-certificate in your IRCC account or a paper certificate by mail (to an address in Canada or the United States, or to the embassy or consulate you chose). If you are not, you get a refusal letter.

6. 6

   Apply for a passport

   Use the certificate to apply for a Canadian passport. Print an e-certificate when you apply.

Apply for a new certificate if yours is lost, stolen, damaged or destroyed, out of date (for example after a legal name change) or contains an error. If IRCC approves the application, your current certificate is cancelled.

• Return old certificatesYou may not hold more than one valid certificate. Send any original certificates you have; IRCC must receive them before it issues a new one. If you later find one you declared lost, send it back.
• Replacing an e-certificateDelete and destroy all printed and digital copies when you apply, and do not download another copy until IRCC decides. If you only lost access to your IRCC Portal account, reset your password instead.
• Citizenship cardsIRCC stopped issuing cards in February 2012, but a card you have is still valid proof. If you replace or update it, you receive a certificate.
• Do not laminateLaminating or re-laminating a proof of citizenship makes it invalid.

Replacement and update applications are made on paper. A lost Canadian birth certificate is replaced by the province or territory that issued it, although you may apply for a citizenship certificate instead.

A search of citizenship records confirms when a person became a citizen, or that they are not one. If IRCC finds a record, it sends a letter valid for 1 year; for a deceased person the letter does not expire.

You can apply online only for your own records. For someone else's, apply on paper: a living person must sign their consent, and for a person who died less than 20 years ago you must show proof of death, your relationship and your legal right to the information.

IRCC may process a certificate faster in some cases, for example to avoid harm or hardship, to move a minor child born abroad to a Canadian parent to Canada, to help with statelessness, to travel because of a death or serious illness when you cannot get a passport from your other country, to renounce a foreign citizenship by a deadline, for a job or school, or to access benefits such as a pension, health care or a social insurance number.

A dual citizen of a visa-exempt country can also ask for urgent processing with proof of air travel to Canada within 6 months of the application date. Include an explanation letter and supporting documents, such as a ticket with proof of payment or an employer letter. IRCC reviews each request and says it cannot promise the certificate will arrive in time.

Urgent searches of records are possible too, for example to confirm to a foreign government that you are not a citizen, to administer an estate, or for a job.

You cannot get a refund once IRCC starts processing. If IRCC finds you are not a citizen, it sends a refusal letter and keeps the fee. Other costs can include official records from other countries, translations and affidavits.

Processing times below are IRCC's live figures for proof of citizenship. IRCC says to add 3 to 4 months for mailing if you live outside Canada and the United States and apply through an embassy, high commission or consulate, and 6 to 8 months if you apply for a minor living outside Canada and the United States directly to the Case Processing Centre in Sydney, Nova Scotia.

• Check the detailsMake sure the information on your certificate is correct and keep it safe. An e-certificate number starts with X and a paper one with K.
• Effective dateIf a parent passed citizenship to you, the effective date is your date of birth. If a change in the law restored your citizenship, it is the date of restoration.
• PassportApply for a Canadian passport before you travel. Children 15 and under can use a certificate, card or birth certificate instead of a passport only when travelling between Canada and the United States by land or sea.
• Your other nationalityIf you are unsure whether applying affects your citizenship of another country, ask that country's embassy, high commission or consulate.
