Many people may already be Canadian citizens without knowing it.
Canada’s citizenship rules changed significantly on December 15, 2025, when Bill C-3 came into effect. The new law removed the first-generation limit that had previously stopped Canadian citizenship by descent from being passed beyond one generation born outside Canada.
Many people who were once considered ineligible may now qualify for Canadian citizenship through their family history. As a result, thousands of people who were previously excluded now have an opportunity to confirm their citizenship.
Applicants can check their eligibility for proof of Canadian citizenship before gathering supporting documents.
Even with these changes, many people still believe they do not qualify because of common misunderstandings about the law. Below are seven of the most common reasons people think they are not eligible and why those assumptions are often incorrect.
So, without further ado, let us begin!
Many Grandparents Were Born In Canada But Left Years Ago
Many people believe that a grandparent who left Canada many years ago cannot help them qualify for citizenship. In reality, that is often not true.
A grandparent who was born in Canada may provide one of the strongest foundations for a citizenship by descent claim.
Canada generally grants citizenship to people born in the country. Whether that grandparent moved away as a child, lived abroad for decades, or never returned does not usually affect their citizenship.
The important question is whether that grandparent was still a Canadian citizen when the applicant’s parent was born.
If that was the case, the parent may have automatically become a Canadian citizen, even if they were born outside Canada. Since Bill C-3 removed the first-generation limit for many applicants, that citizenship can now continue to later generations.
If eligibility is confirmed, the applicant can apply for proof of Canadian citizenship. Once approved, the citizenship certificate can be used to apply for a Canadian passport.
Some Canadian Ancestors Are Several Generations Back
Some people think a Canadian ancestor who lived several generations ago is too distant to count.
The current rules do not automatically disqualify someone simply because the Canadian ancestor is a great-grandparent or even further back.
Instead, each generation must show that Canadian citizenship passed from one parent to the next at the time each child was born.
For example, if a great-grandparent was a Canadian citizen when the grandparent was born, the grandparent may also have become a citizen. If the grandparent was a citizen when the parent was born, citizenship could continue through the family line.
Because the first-generation limit has been removed in many cases, this chain may now continue to the present generation.
Applications involving several generations usually require more documents to prove each family connection, but a longer family history does not automatically prevent someone from qualifying.
Being Born Or Raised Outside Canada Does Not Always Prevent Eligibility
Many people believe that living in Canada or being born there is necessary to qualify.
For citizenship by descent, this is usually not the case.
If a parent was already a Canadian citizen when the applicant was born, the applicant may already be a Canadian citizen as well, regardless of where the birth took place.
For many people born outside Canada before December 15, 2025, there is generally no requirement to have lived, worked, or studied in Canada before applying for proof of citizenship.
Parents May Never Have Claimed Canadian Citizenship
Some families never applied for Canadian passports or citizenship certificates because they never realized they were entitled to Canadian citizenship.
However, citizenship by descent does not depend on whether someone claimed it.
A parent may have been a Canadian citizen throughout life without ever holding a passport or citizenship certificate.
If the parent was legally a Canadian citizen, then citizenship may still pass to the next generation, even if no official documents were previously requested.
The proof of citizenship application simply confirms an existing legal status rather than creating a new one.
Families May No Longer Have Strong Ties To Canada
Many families lost contact with Canada generations ago.
Some no longer have relatives living there. Others have never visited Canada, do not own property, and have no ongoing connection to the country.
These factors generally do not affect citizenship by descent.
Eligibility depends on documented family relationships and citizenship history, not on current family connections.
Even families that have lived outside Canada for many generations may still qualify if they can establish the required family lineage.
Some Canadian Ancestors No Longer Have Birth Records
Many people worry that older birth records no longer exist.
Fortunately, this is not always the case.
Provincial and territorial vital statistics offices, along with historical archives, often keep records going back many decades or even more than a century.
These offices can often issue certified copies of birth records needed to support a citizenship by descent application.
If an official record cannot be located, IRCC may accept a written explanation together with evidence showing that reasonable efforts were made to obtain the document. Alternative supporting records may also help establish the family connection.
Many provinces, including Nova Scotia, Ontario, and Quebec, maintain historical records that may assist applicants researching their family history.
Surname Changes Do Not Automatically Affect Eligibility
Surname changes are another reason many people believe their application cannot succeed.
However, a name change alone does not usually break the family connection.
Marriage certificates often provide the link between a person’s maiden name and married name.
These records help connect birth certificates, marriage records, and other official documents issued under different surnames.
Provincial and territorial vital statistics offices often maintain marriage records along with birth and death records, making it easier to prove the relationship between generations.
By collecting the correct supporting documents, applicants can usually establish the necessary family connections despite surname changes.
Canada’s updated citizenship by descent rules have created new opportunities for many families with Canadian ancestry. Although every case depends on individual family history and supporting evidence, many people who once believed they were not eligible may now have a valid claim.
For anyone with a Canadian parent, grandparent, or ancestor, researching family records may reveal a citizenship that has existed all along.
Note: People born or adopted outside Canada on or after December 15, 2025, to a Canadian parent who was also born or adopted outside Canada must meet an additional physical presence requirement. In these cases, the Canadian parent must have lived in Canada for at least 1,095 days before the child’s birth or adoption.
