Born abroad to a Canadian parent? Learn if Bill C-3 affects your eligibility for Canadian citizenship by descent and how to apply for proof of citizenship.

If you were born outside Canada to a Canadian parent, you may already be a Canadian citizen by descent under the Citizenship Act. In many cases, eligible individuals acquire Canadian citizenship automatically at birth and do not need to apply to become Canadian citizens. Instead, they must apply for a Proof of Citizenship (Citizenship Certificate) to obtain official confirmation of their citizenship status.

Recent amendments under Bill C-3 have expanded eligibility for certain individuals, making it important to understand the current citizenship by descent rules before submitting an application. Determining your eligibility and preparing the required documentation can help ensure a more efficient application process.

This guide explains who may qualify for Canadian citizenship by descent, how the recent legislative changes may affect eligibility, the documents typically required, the steps to apply for a Proof of Citizenship, and what to expect after your application is submitted. Continue reading to gain a clear understanding of the process and the requirements for confirming your Canadian citizenship.

What Is Canadian Citizenship by Descent?

Definition

Canadian citizenship by descent recognizes individuals who are Canadian citizens from birth because they were born outside Canada to a Canadian parent who met the requirements under the Citizenship Act. Canadian citizenship by descent allows eligible individuals to claim Canadian citizenship through their Canadian lineage, provided they meet the requirements of Canada's citizenship laws and the provisions in effect at the time of their birth.

If you qualify, you are considered a Canadian citizen under the law and are recognized as Canadian from birth. Rather than applying for citizenship through a grant of citizenship, eligible individuals apply for a Citizenship Certificate to obtain official confirmation of their Canadian citizenship status.

Proof of Citizenship vs. Canadian Passport

Although both documents are related to Canadian citizenship, they serve different purposes:

Citizenship Certificate (Proof of Citizenship): An official document issued by Immigration, Refugees and Citizenship Canada (IRCC) that confirms you are a Canadian citizen.
Canadian passport: A travel document issued to Canadian citizens that allows international travel and serves as proof of identity and citizenship while travelling.

If you are claiming Canadian citizenship by descent and have never received official proof of your citizenship, you generally must apply for proof before applying for your first Canadian passport. There is generally no deadline to apply for proof of citizenship, although obtaining a Citizenship Certificate is required before many citizenship-related services.

Who Qualifies for Canadian Citizenship by Descent?

Born Outside Canada to a Canadian Parent

Canadian citizenship by descent generally applies to individuals born outside Canada to a Canadian parent who meets the requirements of the Citizenship Act. Eligibility depends on the citizenship rules in effect when you were born and your family's circumstances. If you qualify, you are a Canadian citizen by law from birth and can apply for a Proof of Citizenship (Citizenship Certificate) to obtain official confirmation of your status.

How Bill C-3 Changed Citizenship by Descent Rules

After the Government of Canada passed Bill C-3, the amendments to the Citizenship Act came into force on December 15, 2025, expanding Canada's citizenship by descent framework. Previously, Canadian citizenship by descent generally applied only to the first generation born outside Canada under the first-generation limit to citizenship. This prevented many children born or adopted abroad from automatically receiving Canadian citizenship if their Canadian parent was also born or adopted outside Canada.

Under the amended law, citizenship transmission beyond the first generation is permitted if the Canadian parent demonstrates a substantial connection to Canada by having accumulated at least 1,095 days (three years) of physical presence in Canada before the child's birth or adoption. The Canadian parent must meet this statutory requirement before Canadian citizenship can be passed to later generations.

How Bill C-3 Restored Citizenship for Many "Lost Canadians"

The amended law restores or grants Canadian citizenship to many individuals who were previously excluded because of the first-generation limit or other provisions of earlier citizenship laws. Depending on the circumstances, some people are automatically recognized as Canadian citizens, while others may claim citizenship by obtaining a Proof of Citizenship (Citizenship Certificate). Eligibility continues to depend on the applicable requirements of the Citizenship Act.

Situations That May Affect Your Eligibility

Additional review may be required if you were adopted outside Canada, have missing or incomplete records, or your application involves legal name changes, parentage issues, or other complex family circumstances.

Applications involving a grandparent, great-grandparent, or another Canadian ancestor may require documents establishing the line of descent. The entire chain of descent must be supported by official records so Immigration, Refugees and Citizenship Canada (IRCC) can determine whether the requirements for Canadian citizenship by descent have been met.

Documents Required for a Proof of Citizenship Application

Identity Documents

Provide valid identity document(s) to confirm your identity. Depending on your age and circumstances, IRCC generally requires identification that includes:

Your full name
Date of birth
Photograph
Signature (if applicable)

Birth Certificates and Family Relationship Documents

Provide documents that establish your relationship to your Canadian parent, such as:

Your birth certificate.
Other civil documents, if needed, to confirm your parent-child relationship.

Proof That Your Parent Was a Canadian Citizen

Submit evidence showing your parent was a Canadian citizen at the time of your birth. Acceptable documents may include:

Canadian birth certificate
Canadian citizenship certificate
Other proof of Canadian citizenship accepted by IRCC

If your parent was born in Canada, a provincial or territorial birth certificate is often sufficient to establish citizenship. If your parent was also born or adopted outside Canada, additional documentation may be required to determine eligibility under the current citizenship by descent framework.

Name Change or Supporting Civil Documents (If Applicable)

If the information on your documents does not match, include supporting records such as:

Legal name change certificate.
Marriage certificate.
Adoption records.
Other civil documents that explain differences in names or family relationships

Certified Translation Requirements

If any supporting document is not in English or French, it must be accompanied by a certified translation that meets IRCC requirements. Depending on who completed the translation, IRCC may also require a translator's affidavit. Providing complete and properly translated documents can help avoid processing delays.

Every translation undergoes thorough quality checks to ensure accuracy, consistency, and confidentiality. We help applicants prepare complete, properly translated documents for Canadian citizenship applications. Contact us for a quote.

How to Apply for Proof of Canadian Citizenship Certificate

Reviewing supporting documents before submitting a Proof of Citizenship application.

Step 1: Confirm Your Eligibility

Before applying, confirm that you qualify for Canadian citizenship by descent under the Citizenship Act. Review your family history, verify that your Canadian parent was a Canadian citizen when you were born, and determine whether you meet the applicable eligibility requirements.

If your case involves historical citizenship laws or complex family circumstances, consulting an immigration lawyer may help clarify your eligibility.

Step 2: Gather the Required Documents

Collect all required documents before applying, including proof of identity, your birth certificate, documents showing your relationship to your Canadian parent, and proof of your parent's Canadian citizenship.

If your application involves multiple generations of Canadian citizenship by descent, additional records may be needed to establish your family's line of descent and allow Immigration, Refugees and Citizenship Canada (IRCC) to assess your eligibility.

Step 3: Complete and Submit Your Application

Complete the Application for a Citizenship Certificate (Proof of Citizenship), pay the required processing fee, and submit your application with all supporting documents according to IRCC's instructions.

A Citizenship Certificate confirms existing Canadian citizenship and does not grant citizenship. If you are not already a Canadian citizen, you must apply through the appropriate citizenship process, if eligible, under the Citizenship Act.

What Happens After You Apply?

Processing Times

After Immigration, Refugees and Citizenship Canada (IRCC) receives your application, it reviews your forms and supporting documents under the amended Citizenship Act to determine whether your citizenship may be recognized and whether you qualify for a Citizenship Certificate. Processing times vary depending on application volume, the completeness of your application, and whether additional review is required.

If IRCC Requests Additional Documents

During the review process, IRCC may request additional documents or information if more evidence is needed to confirm your identity, family relationship, or eligibility under Canada's citizenship framework. Responding by the specified deadline can help avoid unnecessary processing delays and delays in Canadian immigration and citizenship services.

After Receiving Your Citizenship Certificate

If your application is approved, IRCC will issue a Citizenship Certificate, your official proof of Canadian citizenship. You can use it to apply for a Canadian passport and access government services that require proof of citizenship.

For application updates, contact Immigration, Refugees and Citizenship Canada (IRCC), the federal citizenship department. Canada recognizes dual citizenship and multiple citizenship, so people born with or entitled to another nationality may also hold citizenship in another country if that country's laws permit.
