This update is part of the Bill C-3 citizenship by descent hub, with the Citizenship guide. A criminal record does not impact a claim for Canadian citizenship by descent, which relies on law and lineage. This status differs from Canadian passport applications, which can be affected by a criminal record. The distinction is important for individuals confirming their Canadian citizenship and securing travel documents. Many Americans with Canadian ancestry have applied for citizenship certificates since Bill C-3 came into force on December 15, 2025.

Bill C-3 amended the Citizenship Act, removing the first generation limit. This rule, established in 2009, previously prevented Canadian citizenship from passing to children born abroad if their Canadian parent was also born abroad. Now, most individuals born outside Canada before December 15, 2025, are citizens if their parent was a Canadian citizen, including those whose parent gained citizenship via the 2025 amendments. For children born abroad on or after December 15, 2025, a Canadian parent born abroad must have resided in Canada for at least 1,095 days before the child's birth or adoption.

Many Americans qualifying for citizenship by descent are already Canadian citizens, holding dual US Canadian citizenship. These citizens possess the right to enter, live, work, and study in Canada without a visa or permit. A criminal record does not affect their citizenship or their right to enter Canada. However, a criminal record can impact a Canadian passport application if open charges, a current sentence, or a passport offence exist. Foreign nationals, including US citizens without Canadian citizenship or permanent residence, may face criminal inadmissibility to Canada due to a criminal record, even for a US misdemeanor like a DUI. Unlike citizenship by descent, naturalization applications consider an applicant's criminal history, potentially barring a grant of citizenship under specific conditions.

Upon receiving proof of citizenship, individuals can apply for a Canadian passport. Immigration, Refugees and Citizenship Canada's Passport Program manages these applications under the Canadian Passport Order. The Minister may refuse a passport based on criminal matters, including current charges for an indictable offense in Canada or abroad, conviction of a passport offense, imprisonment, or court conditions restricting travel or passport possession. Applicants can seek judicial review from the Federal Court to challenge a refusal. Americans with Canadian ancestry can apply for a citizenship certificate by mail to Immigration, Refugees and Citizenship Canada, submitting documentation, a form, photographs, a fee, and identity documents.

Citizenship by descent is determined by law and lineage, not character, meaning a criminal record does not affect this status. While Canadian citizens retain an unconditional right to enter Canada, a criminal record can still impact their ability to secure a Canadian passport. This distinction is crucial, differing from naturalization applications and entry requirements for foreign nationals with criminal records.
