Understanding Canadian Citizenship Through Grandparents

Discovering your Canadian roots can open the door to citizenship through your grandparents. This pathway provides a unique opportunity for those with a Canadian family lineage to claim citizenship, even if they were born elsewhere. The process hinges on proving direct descent from a Canadian grandparent and understanding specific eligibility criteria, which can vary based on historical amendments to citizenship laws.

This guide aims to simplify the complexities and offer insights into potential challenges. It also highlights the importance of legal assistance and resources available to support you on this journey. Whether you’re seeking dual citizenship or an enriching personal connection to your heritage, this information could be your key to Canadian citizenship through grandparents.

To obtain Canadian citizenship through grandparents, it’s important to understand the eligibility criteria that focus on proving a direct lineage. This means that one of your grandparents must have been born in Canada or acquired Canadian citizenship and you must have documentation to prove this relationship. Establishing this lineage often requires birth certificates and other family records that clearly show the link between you and your Canadian ancestor.

Historically, Canadian citizenship laws have evolved, impacting claims through grandparents. Before 1947, Canada was largely governed by British nationality laws. The introduction of the Canadian Citizenship Act in 1947 marked the beginning of Canadian nationality law as distinct from British law. Changes over the years have affected who is eligible to pass on citizenship, especially regarding descent.

For instance, amendments such as the 2009 Bill C-37 impacted second-generation citizenship and limited the ability to claim citizenship for those born outside Canada to Canadian parents or grandparents. Knowledge of these changes is vital when considering citizenship via grandparents.

Bill C-3

What Is Bill C-3 and Why It Matters

On December 15, 2025, Bill C-3, An Act to amend the Citizenship Act came into force in Canada. This law changes long-standing rules about how Canadian citizenship is passed down to children born outside Canada. Specifically:

• It ends the strict first-generation limit for those born before December 15, 2025 — meaning many people born abroad to Canadian parents or grandparents are now recognized as Canadian citizens if they would have qualified “but for” the old rules.
• For those born on or after December 15, 2025, the law still allows citizenship to be transmitted beyond the first generation but now with a “substantial connection” requirement. That means the Canadian parent (if born abroad) must have spent at least 1,095 days (three years) physically present in Canada before the child’s birth or adoption.
• The new law also applies to children adopted abroad, timelines for pending applications, and provides ways to obtain proof of citizenship.

In short:

Born before Dec 15, 2025: You may be automatically considered a Canadian citizen and can now apply for proof of citizenship.
Born on/after Dec 15, 2025: Citizenship depends on the 3-year substantial connection test for Canadian parents born abroad.

Eligibility

Who Qualifies Under Bill C-3

Classic Citizenship by Descent (Parents)

If you were born outside Canada to a Canadian parent, you’re generally eligible to apply for citizenship if:

• One of your parents was a Canadian citizen at the time of your birth (by birth or by earlier grant), or
• You qualify under the new law because you would have been a citizen but for the old first-generation limit.

Grandchildren / Later Generations

People born abroad to Canadian parents who themselves were born abroad may also now qualify:

• Before Dec 15, 2025: These individuals are often automatically eligible.
• After Dec 15, 2025: Eligibility depends on the Canadian parent’s Substantial Connection Test (see above).

Adopted Children

Adopted children born abroad may also qualify under Bill C-3, similar to biological children, if adoption criteria and timing requirements are met.

Key Terms Explained

First-Generation Limit: Previously, Canadian citizenship by descent was mostly limited to one generation born abroad. Bill C-3 removes that limit for people born before Dec 15, 2025.

Substantial Connection: A Canadian parent born abroad must show at least 1,095 days (three years) physically present in Canada before the birth or adoption of the child (for births after Dec 15, 2025).

Documents

For most citizenship by descent applications, you’ll need:

Your birth certificate showing parental information.

Canadian parent’s birth certificate showing parental information.

Canadian Grandparents birth certificate

Canadian Citizenship certificate if applicable

Translations for any documents not in English/French (certified).

Marriage certificates (if names differ across documents).

Adoption documents, if applicable.

If you’re missing documents (e.g., your parent’s citizenship proof), there are strategies to reconstruct a file using alternate evidence, secondary documents, or official records requests. We can advise about this and how to obtain

Process

 How to Apply — Step by Step

1. Confirm eligibility under Bill C-3 rules.
2. Gather all required documents (birth certificates, proof of citizenship, translations).
3. Complete the application
4. Pay the application fees
5. Submit to IRCC and track your file.
6. Respond promptly to any IRCC requests for additional evidence.
7. Receive your Citizenship Certificate once approved.

 Common Challenges

Missing documents or inaccessible records — can delay or complicate processing.
Understanding generational eligibility — especially for older ancestors.
Proving substantial connection for parents born abroad (post-Dec 15, 2025 births).

Dealing with complex family histories can be another hurdle. Families that have moved across borders or experienced name changes might face additional layers to verify lineage. Navigating these complexities requires patience and detailed record-checking to ensure the family ties are clear and traceable.

Considerations also arise regarding dual citizenship. If your home country and Canada both permit dual nationality, there could be certain benefits or restrictions to be aware of, such as tax obligations or mandatory citizenship activities, like military service, in your home country. Understanding these implications is crucial as each country has its own nationality laws that could influence your citizenship application process.

We help clients address these hurdles with targeted evidence strategy and case management.
