Canadian Citizenship Through a Grandparent: How Bill C-3 Could Make You Eligible

Have you recently discovered that your grandparent was Canadian? Or perhaps you've always known but were told years ago that you didn't qualify for Canadian citizenship because you were born outside Canada.

If so, it may be time to look again.

On December 15, 2025, significant changes to Canada's Citizenship Act came into force through Bill C-3. These changes expanded who can obtain Canadian citizenship by descent, creating new opportunities for many people who were previously excluded under the old rules.

If you have a Canadian grandparent, here's what you need to know.

What Is Bill C-3?

For many years, Canada's Citizenship Act included what was known as the first-generation limit. Generally, Canadian citizenship by descent could only be passed to the first generation born outside Canada.

This meant that if your parent was born outside Canada to a Canadian citizen, they could often inherit Canadian citizenship. However, if you were also born outside Canada, you were frequently unable to inherit citizenship yourself.

As a result, many families with genuine Canadian roots were prevented from passing citizenship to future generations.

Bill C-3 changed these rules.

The legislation introduced new provisions that recognize citizenship for many people who were previously excluded and allows Canadian citizenship by descent to extend beyond the first generation in certain circumstances.

For many individuals with Canadian ancestry, this represents an opportunity that simply did not exist before.

Can You Get Canadian Citizenship Through Your Grandparent?

Possibly.

Whether you qualify depends on your family's citizenship history, when you were born, and how the law applies to your particular circumstances.

The rules differ depending on whether you were born before or on or after December 15, 2025.

If You Were Born Before December 15, 2025

One of the most significant features of Bill C-3 is that it includes retroactive provisions for people who were previously excluded by the first-generation limit.

In many cases, a parent who was previously prevented from passing on Canadian citizenship may now be recognized as having been a Canadian citizen under the amended legislation. If that applies in your family's situation, you may also have become a Canadian citizen at birth.

These changes are particularly important for many people who have long been referred to as "Lost Canadians"—individuals who missed out on Canadian citizenship because of previous legislative restrictions rather than anything they did themselves.

Every family history is different, so determining eligibility requires a careful review of the citizenship chain across each generation.

If You Were Born On or After December 15, 2025

For children born on or after December 15, 2025, Canadian citizenship by descent may still extend beyond the first generation born abroad, but an additional requirement now applies.

The Canadian parent who was born outside Canada must have accumulated at least 1,095 days (three years) of physical presence in Canada before the child's birth.

This means actual physical presence in Canada—not simply holding Canadian citizenship.

The purpose of this requirement is to maintain a meaningful connection between future generations and Canada.

Why So Many People Think They Don't Qualify

Many people investigated their eligibility years ago and were correctly told they did not qualify under the law that existed at the time.

Bill C-3 has changed that for many families.

If you were previously told that Canadian citizenship could not pass through your grandparent because of the first-generation limit, it may be worthwhile to have your eligibility reviewed again under the current legislation.

Important Things to Know About Canadian Citizenship by Descent

Older Family Histories Can Be More Complex

Most people born in Canada automatically became Canadian citizens.

If your grandparent was born before January 1, 1947, determining whether they were a Canadian citizen at the relevant time can be more complex. Canada did not create Canadian citizenship until January 1, 1947, and earlier nationality laws sometimes affect whether citizenship could be passed to later generations.

These cases often require a careful review of your family's history and the citizenship laws that applied over time.

How Your Parent Became a Canadian Citizen May Matter

Your parent may have been born in Canada, acquired Canadian citizenship by descent, or become a Canadian citizen through naturalization.

Any of these circumstances may support your eligibility, provided your parent was already a Canadian citizen before your birth and all other legal requirements are met.

You Do Not Need to Travel to Canada

If you qualify for Canadian citizenship by descent, you can apply for a Canadian citizenship certificate from outside Canada.

The application is completed through Immigration, Refugees and Citizenship Canada (IRCC), and travelling to Canada is not required simply to obtain proof of your citizenship.

Canadian Citizenship by Descent Is Full Citizenship

If you qualify, you become a full Canadian citizen with the same legal rights and responsibilities as other Canadian citizens.

This includes the right to:

• Live and work anywhere in Canada

• Apply for a Canadian passport

• Vote in Canadian elections (once eligible)

• Access the rights and protections available to Canadian citizens

• Pass Canadian citizenship to your own children where permitted under the current law

  
  

How Long Does the Process Take?

As of July 2026, IRCC is reporting processing times of approximately 15 months for many Canadian citizenship certificate applications.

Processing times may change over time depending on application volumes, so it is always advisable to check the latest information when planning your application.

Every Family's Situation Is Different

Canadian citizenship law can be surprisingly complex.

A person's eligibility often depends on factors including:

• when each generation was born;

• whether family members were Canadian citizens at the relevant time;

• changes to citizenship legislation over many decades; and

• the documents available to prove your family history.

  
  

Two families that appear almost identical can have very different legal outcomes.
