Canadian Citizenship by Descent 2026: Bill C-3 Rules Explained

The rules for obtaining Canadian citizenship by descent changed significantly on 15 December 2025. Following the passage of Bill C-3, the Canadian government has expanded eligibility for people born abroad to a Canadian parent, addressing long-standing issues for those previously excluded by the first-generation limit.

This landmark legislation creates two distinct pathways to citizenship by descent depending on an individual's date of birth. For those born before 15 December 2025, the law retroactively grants citizenship to many in the second and subsequent generations born abroad, a group often referred to as 'Lost Canadians'. For children born on or after this date, the rules introduce a new 'substantial connection' test for their Canadian parent if that parent was also born outside Canada. This means that while the rigid first-generation limit is gone, a new condition has taken its place for future generations.

Understanding which set of rules applies to you is the first step in claiming your right to Canadian citizenship. This article explains the changes under Bill C-3, who now qualifies for citizenship and the practical steps for applying for your proof of citizenship, the essential document that confirms your status and allows you to obtain a Canadian passport.

What changed under Bill C-3

To understand the importance of Bill C-3, it is necessary to look at the previous law. In 2009, the Citizenship Act was amended to include a 'first-generation limit'. This rule meant that a Canadian citizen parent who was born outside Canada could not pass on citizenship to their own child if that child was also born outside Canada. Citizenship could only be passed down by one generation born abroad. This created significant challenges for many families and led to a growing number of people with strong ties to Canada being denied citizenship status simply because of where they and their parents were born.

These individuals became known as 'Lost Canadians'. They were often the children or grandchildren of Canadians who had worked abroad for the government or private companies, yet they had no pathway to citizenship themselves despite their direct lineage. Bill C-3, formally titled An Act to amend the Citizenship Act, 2025, was designed specifically to remedy this situation. The bill received Royal Assent on 20 November 2025 and its provisions came into force on 15 December 2025.

The most significant change is the removal of the first-generation limit for individuals born before the act came into force. The legislation retroactively grants citizenship to people born abroad in the second or later generations, as long as their Canadian parent was also born abroad to a Canadian parent. This automatically restores citizenship to many who had lost it or never qualified under the 2009 rules.

However, for children born or adopted on or after 15 December 2025, the government has introduced a new framework. The hard first-generation limit has been replaced with a conditional rule based on a parent's 'substantial connection' to Canada. Under this new rule, a Canadian parent who was themselves born abroad can pass on citizenship to their child born abroad if they can demonstrate at least 1,095 days of physical presence in Canada before the child's birth or adoption. This change aims to balance the desire to be more inclusive with the principle that citizenship should be tied to a tangible connection to the country.

Who qualifies (born before vs on or after 15 December 2025)

The new legislation effectively splits eligibility for Canadian citizenship by descent into two distinct categories based on a single date: 15 December 2025. Your date of birth determines which set of rules you must follow. It is crucial to identify which category you fall into to understand your potential pathway to citizenship.

Born Abroad Before 15 December 2025

If you were born outside Canada before 15 December 2025, the rules have been simplified and expanded in your favour. The previous first-generation limit no longer applies to you. You are a Canadian citizen if you were born to a Canadian parent, regardless of where that parent was born. This is a significant change that primarily benefits second and subsequent generations born abroad.

For example, consider the question of Canada citizenship by descent from a grandparent. If your mother was born in Germany to a Canadian parent (your grandmother, who was born in Canada) and you were also born in Germany in 1995, under the old rules you would not be a citizen because your mother was the first generation born abroad. Under the new rules of Bill C-3, you are now considered a Canadian citizen because the first-generation limit is retroactively removed for your birth date. Your claim is valid because your lineage connects directly to a Canadian.

This change rectifies the status of many 'Lost Canadians' and simplifies the process for anyone born before the cut-off date with a Canadian parent or grandparent in their direct line. Your eligibility now depends only on having a Canadian parent at the time of your birth.

Born or Adopted Abroad On or After 15 December 2025

If your child is born or adopted outside Canada on or after 15 December 2025, a different set of rules applies. While the absolute first-generation limit is gone, it has been replaced by a new condition known as the 'substantial connection' test.

In this scenario, if the child's Canadian parent was born in Canada, citizenship is automatically passed down. There are no additional requirements.

However, if the child's Canadian parent was also born outside Canada (making the child the second generation born abroad), that parent must prove they have a substantial connection to Canada. This is defined as having accumulated at least 1,095 days of physical presence in Canada before the birth or legal adoption of the child. This rule ensures that the parent has spent a significant amount of time in Canada, thereby establishing a meaningful link that can be passed to the next generation.

This new test provides a clear and attainable pathway for Canadian expatriate families to pass on citizenship, something that was impossible under the previous law, but it requires proactive planning to meet the physical presence requirement.

The 1,095-day substantial connection test

The substantial connection test is a core component of the new citizenship rules for children born abroad on or after 15 December 2025. This test applies specifically and only to Canadian parents who were themselves born outside of Canada and wish to pass on citizenship to their children also born outside of Canada.

The requirement is precise: the Canadian parent must have been physically present in Canada for a cumulative total of at least 1,095 days before the child's birth or adoption. This period equates to three full years. It is important to note that the days do not need to be consecutive. A person could accumulate the time over several different periods spent in Canada throughout their life. The critical factor is that the total of 1,095 days must be met before the child is born.

This test is designed to demonstrate a meaningful and tangible link to Canada. The logic is that a parent who has lived in Canada for a significant period has been integrated into Canadian society, understands its values and can pass this connection on to their child. It moves away from the previous rigid system, where a person could have spent their entire life in Canada from infancy but was still unable to pass on citizenship if they happened to be born abroad.

To prove this physical presence, parents will need to provide comprehensive documentation to Immigration, Refugees and Citizenship Canada (IRCC). While IRCC will publish a definitive list of acceptable evidence, applicants should expect to provide records that can substantiate their time in the country. This could include a combination of documents such as:

• School or university transcripts showing dates of attendance.
• Employment records, pay stubs or letters from employers.
• Canadian income tax assessments (Notice of Assessment).
• Rental agreements or property ownership documents.
• Provincial health records.
• Entry and exit records from passports.

It is essential for Canadian parents living abroad who may have children in the future to begin tracking and preserving these documents carefully. The burden of proof will be on the applicant to demonstrate that the 1,095-day threshold has been met. For official guidance on what constitutes valid proof, applicants must consult the specific instructions provided by IRCC for their application.

How to apply for a citizenship certificate

Acquiring citizenship by descent under the new rules is not an automatic process in a practical sense. While the law may grant you citizenship status, you must formally apply to the Canadian government to have it recognised. The official document that proves your Canadian citizenship is the citizenship certificate. You will need this document to apply for a Canadian passport and access other rights and services as a citizen.

The application is made to Immigration, Refugees and Citizenship Canada (IRCC). The process requires careful attention to detail and thorough documentation.

1. Determine your eligibility and gather initial documents. The first step is to confirm that you meet the criteria based on your date of birth and your parent's citizenship status. Begin by collecting core documents like your full birth certificate and your Canadian parent's proof of citizenship, such as their Canadian birth certificate or citizenship certificate.

2. Complete the correct application form. You will need to fill out the 'Application for a Citizenship Certificate (Proof of Citizenship)'. It is critical to use the most current version of the form available on the IRCC website. The forms are detailed and require precise information about yourself, your parents and in some cases, your grandparents.

3. Gather all required supporting documents. IRCC provides a detailed document checklist with the application package. You must provide all the necessary documents from this list. This will include identity documents, birth certificates to prove lineage and any name change documents. All documents that are not in English or French must be accompanied by a certified translation. If you are applying under the substantial connection test, you will also need to provide the extensive evidence of physical presence in Canada.

4. Pay the application fees. The government charges a fee to process the application. You cannot pay this fee in person or by mail. You must pay the fees online through the IRCC payment service and include a copy of the receipt with your application. The exact fee amount can change, so you must check the official IRCC website for the current fee schedule before paying.

5. Submit your application. Once the forms are complete, the fees are paid and all supporting documents are collected and organised, you must submit the entire package to the IRCC case processing centre as specified in the application guide. Be sure to follow the mailing instructions carefully.

6. Wait for processing and decision. After submission, your application will be reviewed by an IRCC officer. IRCC does not provide a fixed processing time for citizenship certificate applications as it can vary widely based on the complexity of the case and application volumes. You can monitor general processing times using the official IRCC processing times tool on their website. If your application is approved, you will receive your citizenship certificate in the mail.

Documents you will need

Gathering the correct documentation is the most critical part of applying for a Canadian citizenship certificate. An incomplete or poorly documented application will lead to delays or rejection. While the exact list of documents can vary depending on your specific situation, you must always follow the official document checklist provided by IRCC. The general categories of documents required are as follows.

• Proof of your identity: You will need a copy of your full birth certificate, which must show your name, date of birth, place of birth and the names of your parents. You will also need to provide copies of government-issued photo identification, such as a passport from another country or a driver's licence.

• Proof of your parent's Canadian citizenship: You must prove that at least one of your biological or legal parents was a Canadian citizen at the time of your birth. The best proof is the parent's Canadian birth certificate (if they were born in Canada) or their Canadian citizenship certificate (if they became a citizen by descent or naturalisation).

• Linking documents: You must provide a clear paper trail that connects you to your Canadian ancestor. Your full birth certificate showing your Canadian parent's name is the primary linking document. If you are claiming citizenship through a grandparent because your Canadian parent was also born abroad (and you were born before 15 December 2025), you will need your parent's birth certificate to link them to your Canadian grandparent.

• Name change documents: If your name or your parent's name has changed since birth (for example, through marriage), you must provide official documents that prove this change, such as a marriage certificate or a legal name change deed.

• Translations: Any document that is not in English or French must be submitted with a complete translation by a certified translator. You must also include a copy of the original document and an affidavit from the translator.

For those applying under the new substantial connection test, an additional category of documents will be required to prove the 1,095 days of physical presence. As mentioned, this could include a wide array of official records. Applicants should check the specific IRCC guide for the definitive list of acceptable evidence.

Dual citizenship

Canada fully recognises and permits dual citizenship. This means that when you claim Canadian citizenship by descent, you will not be asked by the Canadian government to renounce any other citizenship you may currently hold. You can be a citizen of Canada and another country or multiple other countries simultaneously.

This is a significant benefit for those acquiring status through ancestry, as it allows them to maintain their ties to their country of birth or other citizenships. As a dual citizen, you will enjoy the rights and privileges of citizenship in both countries, such as the ability to live, work and vote in both. You will also be able to hold a passport from each country.

However, it is crucial to understand that while Canada permits dual citizenship, your other country of citizenship may not. Some countries have restrictions or prohibitions on holding another nationality. Before beginning your application for Canadian citizenship, you should verify the laws of your other country of citizenship to ensure that acquiring Canadian status will not negatively impact your existing nationality. You can learn more about the policies of different nations in our guide to dual citizenship rules by country in 2026.

Obtaining citizenship by descent through a European Union country can also provide a pathway to living and working across the EU. You can explore these options in our articles on EU citizenship by descent, including specific guides to Irish citizenship by descent and Italian citizenship by descent.

Frequently asked questions

Am I a Canadian citizen if my grandparent was Canadian?

It depends on your birth date and lineage. If you were born before 15 December 2025 and your parent was a Canadian citizen at your birth (even if they were born abroad to a Canadian), you are now likely a citizen. This change under Bill C-3 removes the previous first-generation limit for this group, opening the door for many to claim Canada citizenship by descent through a grandparent.

What is Bill C-3 and when did it become law?

Bill C-3 is an act of the Canadian Parliament that amended the Citizenship Act. Its main purpose was to address the 'Lost Canadians' issue by changing the rules for citizenship by descent. The bill received Royal Assent on 20 November 2025 and its new rules came into force on 15 December 2025. These rules change how citizenship is passed to children born abroad.

I was born abroad to a Canadian parent in 2010. Am I a Canadian citizen?

It depends on where your Canadian parent was born. If your parent was born in Canada, you have been a citizen since birth. If your Canadian parent was also born abroad, under the old rules you would not have been a citizen. However, because you were born before 15 December 2025, the new law retroactively grants you citizenship. You should apply for a proof of citizenship certificate.

My child will be born next year abroad. I was also born abroad. Can they be Canadian?

Yes, potentially. Because your child will be born after the 15 December 2025 cut-off date, you can pass on citizenship if you can prove you have a 'substantial connection' to Canada. This means you must demonstrate that you have been physically present in Canada for at least 1,095 days (three years) before your child is born. The days do not need to be consecutive.

How do I prove the 1,095-day substantial connection to Canada?

You will need to provide documentary evidence to IRCC. While the official checklist should be consulted, this can include school records, employment history in Canada, tax statements, rental agreements and other official documents that show you were living in the country. The burden of proof is on you to demonstrate you meet the cumulative three-year physical presence requirement before your child's birth.

Is a citizenship certificate the same as a passport?

No, they are different documents. A citizenship certificate is the official document that proves you are a Canadian citizen. You must first obtain your citizenship certificate before you are eligible to apply for a Canadian passport. The passport is a travel document, while the certificate is your foundational proof of status. You need the certificate to get the passport.

How long does it take to get a proof of citizenship certificate?

There is no fixed processing time. Wait times can vary significantly based on the number of applications IRCC has received and the complexity of your case. For the most current estimates, you should consult the official processing times tool available on the Immigration, Refugees and Citizenship Canada (IRCC) website. It is best to apply as early as possible.

What are the fees for a citizenship certificate application?

The Canadian government charges a non-refundable processing fee for citizenship certificate applications. The fee amount is subject to change. For this reason, you must always check the official IRCC website for the current fee schedule and payment instructions immediately before you submit your application. You must pay the fee online and include the receipt with your submission.

Am I a Canadian citizen automatically under the new rules?

Legally, yes, the law may grant you citizenship automatically. However, in practice, you are not recognised as a citizen by the government until you have successfully applied for and received your citizenship certificate. You must take the step of formally applying to prove your status. Without this certificate, you cannot get a passport or access other services, so the answer to 'am I a Canadian citizen' is only practically yes after you have your proof.

Can I still be a 'Lost Canadian' after Bill C-3?

Bill C-3 was specifically designed to provide a remedy for the vast majority of 'Lost Canadians' who were excluded by the 2009 first-generation limit. If you were born before 15 December 2025 and had a Canadian parent at birth, you are now likely a citizen regardless of where you or your parent were born. The law has retroactively fixed the status for most people in this situation.
