Can a Criminal Record Affect a Canadian Citizenship by Descent Claim?

Canada’s citizenship by descent rules changed significantly after Bill C-3 came into force on December 15, 2025. Since then, many people with Canadian parents, grandparents or other Canadian ancestors have been exploring whether they may already be Canadian citizens under the law.

One common question is whether a past criminal charge or conviction can affect a claim to Canadian citizenship by descent.

In most cases, the answer is no. Citizenship by descent is based mainly on whether a person meets the legal requirements through their Canadian parent or ancestor. A past criminal record does not normally remove citizenship that a person already has by operation of law.

Does a Criminal Record Affect Citizenship by Descent?

A criminal record generally does not affect whether a person is a Canadian citizen by descent.

Bill C-3 changed the Citizenship Act and removed the previous first-generation limit in many situations. That limit had prevented citizenship from automatically passing to some children born outside Canada when their Canadian parent had also been born abroad.

For many people born outside Canada before December 15, 2025, citizenship may now be recognized if they were born to a parent who was a Canadian citizen, including situations where the parent became recognized as a citizen because of the new amendments.

For children born or adopted outside Canada on or after December 15, 2025, different requirements can apply. In certain cases, a Canadian parent who was also born outside Canada must show that they spent at least 1,095 days in Canada before the child’s birth or adoption.

This means that citizenship by descent is generally determined by the Citizenship Act and the person’s family connection to Canada, rather than by their criminal history.

A Citizenship Certificate Confirms Existing Status

A citizenship certificate does not normally create Canadian citizenship for a person who is already a citizen by descent.

Instead, the certificate serves as official proof of Canadian citizenship.

Once a person is confirmed to be a Canadian citizen, they generally have the right to enter, live, work and study in Canada without needing a visa, study permit or work permit.

This is one of the major differences between citizenship by descent and immigration applications made by foreign nationals.

Where a Criminal Record May Still Matter

Although a criminal record generally does not affect citizenship by descent itself, it can still become relevant in other situations.

One important example is a Canadian passport application.

A citizenship certificate and a Canadian passport are separate documents and are governed by different rules.

A person may already be a Canadian citizen and may have proof of citizenship, but certain criminal matters can still affect whether a passport is issued.

Criminal Issues That May Affect a Canadian Passport Application

Under the Canadian Passport Order, a passport may be refused or restricted in certain circumstances involving criminal matters.

Examples may include situations where a person:

• Is currently facing certain serious criminal charges in Canada
• Is facing charges outside Canada that would be considered serious offences under Canadian law
• Has been convicted of certain passport-related offences
• Is currently in prison
• Is subject to court conditions preventing travel
• Is prohibited by a court from holding or using a passport

These situations are different from simply having an old criminal record.

A conviction from many years ago that has already been fully dealt with may not automatically prevent a person from obtaining a Canadian passport, unless other restrictions still apply.

Anyone facing current criminal charges, court conditions or passport-related issues may want to obtain legal advice before applying for a passport.

Can a Canadian Citizen Be Refused Entry to Canada Because of a Criminal Record?

Canadian citizens have the right to enter Canada.

Once Canadian authorities are satisfied that a person is a Canadian citizen, criminal inadmissibility rules that apply to foreign nationals generally do not prevent that citizen from entering Canada.

However, travellers still need to establish their Canadian citizenship when entering the country.

A Canadian citizenship certificate can help prove citizenship, although travel document requirements may depend on how the person is travelling to Canada.

What Happens If You Are Not a Canadian Citizen?

The situation is very different for someone who does not qualify for Canadian citizenship by descent.

A foreign national with a criminal conviction can potentially be found criminally inadmissible to Canada.

Even offences committed outside Canada, including some driving offences, may create immigration problems depending on how the foreign offence compares with Canadian law.

In some cases, a foreign national may need to address the inadmissibility issue before travelling to Canada.

Possible options can include criminal rehabilitation or a Temporary Resident Permit, depending on the circumstances.

This is why confirming whether a person is already a Canadian citizen can be especially important for individuals with Canadian ancestry and a past criminal record.

Citizenship by Descent vs. Citizenship by Naturalization

Citizenship by descent and citizenship through naturalization are different processes.

A person claiming citizenship by descent is usually asking the government to confirm citizenship that may already exist under Canadian law.

Naturalization, on the other hand, involves a permanent resident applying for a grant of Canadian citizenship.

A permanent resident applying for citizenship must meet several requirements, which may include:

• Physical presence in Canada
• Tax filing obligations
• Language requirements, where applicable
• Citizenship knowledge requirements
• Criminal and security-related requirements

Criminal history can have a much greater impact on a grant of citizenship application.

For example, certain criminal charges, convictions, imprisonment, probation or parole can affect eligibility for naturalization.

A person who is already a Canadian citizen by descent is in a different position because they are not applying to become Canadian. They are applying for proof of a citizenship status they may already hold.

How to Apply for Proof of Canadian Citizenship

Individuals who believe they may be Canadian citizens by descent can apply to Immigration, Refugees and Citizenship Canada for a citizenship certificate.

One of the most important parts of the application is proving the family connection to the Canadian ancestor.

Applicants may need to collect documents such as:

• Birth certificates
• Marriage certificates
• Citizenship certificates
• Naturalization records
• Name change documents
• Adoption documents, where applicable
• Other government-issued civil records

The documents should clearly establish the family connection from one generation to the next.

In multi-generation cases, collecting historical records can be one of the most time-consuming parts of the application process.

Why Accurate Documentation Matters

Citizenship by descent applications can become complicated when records are missing, names have changed, ancestors were born many generations ago or citizenship status changed over time.

Applicants should make sure that each generation in the family line is properly documented.

They should also ensure that the information provided in the application matches the supporting documents.

If there are differences in names, dates of birth, places of birth or other important details, an explanation and additional supporting evidence may be required.
