The changes introduced through Bill C-3 have created new opportunities for many people with Canadian ancestry. If you have a Canadian grandparent or another Canadian ancestor, you may now qualify for Canadian Citizenship by Descent—but having a Canadian relative alone does not automatically make the application successful.

To officially prove your status, you must submit a Proof of Canadian Citizenship application along with documents that establish an unbroken family connection between you and your Canadian ancestor.

What Changed Under Bill C-3?

Following the implementation of Bill C-3 on December 15, 2025, Canada removed the previous first-generation limit on citizenship by descent for eligible individuals born before that date.

This means that many people with Canadian parents, grandparents, or even earlier generations may now qualify as Canadian citizens. However, eligibility still depends on your family’s citizenship history and supporting documentation.

Why the Family Connection Matters

One of the biggest misconceptions is that submitting your grandparent’s Canadian birth certificate is enough.

It isn’t.

Immigration, Refugees and Citizenship Canada (IRCC) requires applicants to provide a complete chain of documents connecting every generation.

For example, if your grandmother was born in Canada and your father was born abroad before you, you would generally need documents such as:

• Your grandparent’s Canadian birth certificate
• Marriage certificate (if their surname changed)
• Your parent’s long-form birth certificate showing your grandparent as the parent
• Your own long-form birth certificate showing your parent

This complete document trail helps IRCC verify both your family relationship and whether Canadian citizenship legally passed from one generation to the next.

Why IRCC Requires an Unbroken Chain

When reviewing a Canadian Citizenship Certificate application, IRCC doesn’t simply verify that one ancestor was Canadian.

The department must confirm that citizenship remained valid throughout every generation leading to you.

Missing records, incorrect documents, or gaps in the family history can delay or even prevent approval.

That is why gathering the correct documentation before applying is extremely important.

When Citizenship by Descent May Not Apply

Even if your grandparent was Canadian, there are situations where citizenship may not pass to future generations.

Some examples include:

• A parent formally gave up (renounced) Canadian citizenship before the child was born.
• A parent became a Canadian citizen only after their child had already been born.
• Required legal conditions for citizenship transmission were not met at the relevant time.

Every family history is different, so eligibility should always be reviewed carefully before submitting an application.

Documents You May Need

Depending on your situation, IRCC may request:

• Canadian birth certificates
• Long-form birth certificates
• Marriage or name change certificates
• Canadian citizenship certificates
• Naturalization records
• Other identity and civil status documents

Preparing these documents correctly can significantly improve the application process.
