Can Your Child Have Dual Citizenship in the U.S. and Canada?

Navigating the world of dual citizenship can feel overwhelming, especially for American families living in Canada or Canadians with ties to the U.S. If you’re wondering whether your child can have dual citizenship in the U.S. and Canada, you’re not alone. Many expat parents want to understand the legalities, benefits, and responsibilities that come with holding two passports from birth or by descent. In this guide, we’ll break down the rules, eligibility, and practical implications—so you can make informed decisions for your family’s future.

Understanding dual U.S.-Canada citizenship: Legal framework and permissions

Let’s start with the basics: both the United States and Canada allow dual citizenship. This means your child can legally be a citizen of both countries at the same time, provided they meet each country’s requirements. Neither government requires a person to choose one citizenship over the other, nor do they penalize dual citizens simply for holding two passports.

Key points to know:

• The U.S. does not formally encourage dual citizenship, but it recognizes it and does not prohibit it.
• Canada fully permits dual or even multiple citizenships.
• Dual citizenship in the U.S. and Canada is common among families with cross-border ties, and both countries have clear legal frameworks to support it.

However, dual citizenship comes with both privileges and obligations. For example, your child may have tax, military, or legal responsibilities in both countries. Understanding these nuances is essential for long-term planning.

Automatic dual citizenship at birth: When children quality by location and parentage

Many children acquire dual citizenship U.S. and Canada automatically at birth, depending on where they are born and the citizenship status of their parents. Here’s how it works:

By birthplace (Jus Soli)

• Canada: Any child born on Canadian soil (with very few exceptions, such as children of foreign diplomats) is automatically a Canadian citizen, regardless of their parents’ citizenship.
• United States: Children born in the U.S. are automatically U.S. citizens, even if their parents are not U.S. citizens.

By parentage (Jus Sanguinis)

• U.S. citizenship by descent: If at least one parent is a U.S. citizen, a child born abroad (including in Canada) may automatically acquire U.S. citizenship at birth, provided certain residency requirements are met by the U.S. citizen parent.
• Canadian citizenship by descent: Children born outside Canada to at least one Canadian citizen parent may also be eligible for Canadian citizenship, but there are some generational limits.

Example: If an American couple living in Toronto has a baby, their child is automatically a Canadian citizen by birth. If at least one parent meets the U.S. residency requirements, the child is also a U.S. citizen at birth—making them a dual citizen from day one.

U.S. citizenship requirements for children born in Canada to American parents

If you’re an American living in Canada and have a child in the country, you’ll want to know how to secure U.S. citizenship for your child. The U.S. has specific rules for transmitting citizenship to children born abroad:

Key requirements

• At least one parent must be a U.S. citizen at the time of the child’s birth.
• The U.S. citizen parent must have lived in the U.S. for a certain period before the child’s birth. For most cases, this means at least five years of physical presence in the U.S., with at least two of those years after the age of 14.

The process

1. Report the birth to the nearest U.S. consulate or embassy in Canada as soon as possible.
2. Apply for a Consular Report of Birth Abroad (CRBA), which serves as proof of U.S. citizenship.
3. Obtain a U.S. passport for your child.

Canadian citizenship by birth and descent: Eligibility rules for American families

For American families in Canada, understanding Canadian citizenship rules is equally important. Here’s what you need to know:

By birth in Canada 

• Automatic citizenship: Any child born in Canada (except to foreign diplomats) is a Canadian citizen, regardless of the parents’ nationality.

By descent (born outside Canada)

• First generation only: Children born outside Canada to a Canadian parent are eligible for Canadian citizenship, but only if the parent was either born in Canada or naturalized as a Canadian citizen. This is known as the “first generation limit.”
• Second generation and beyond: If a Canadian citizen parent was also born outside Canada, their child may not automatically qualify for Canadian citizenship.

Example: If you’re an American married to a Canadian, and your child is born in the U.S., your child can claim Canadian citizenship by descent—provided your Canadian spouse was born in Canada or became a naturalized citizen.

Benefits and responsibilities of dual citizenship for children and families

Holding dual citizenship in the U.S. and Canada opens up a world of opportunities for your child, but it also comes with important responsibilities. Here’s what to consider:

Benefits

• Freedom to live, work, and study in both countries without visas or permits.
• Access to healthcare, education, and social services in both the U.S. and Canada.
• Ability to own property and invest in both countries.
• Cultural and family connections on both sides of the border.

Responsibilities

• Tax obligations: The U.S. taxes its citizens on worldwide income, even if they live in Canada. This means your child may need to file U.S. tax returns (and possibly Canadian returns) as an adult.
• Military service: While neither country currently enforces mandatory military service, dual citizens should be aware of any future changes.
• Legal compliance: Dual citizens must follow the laws of both countries, which can sometimes create complex situations (for example, travel restrictions or legal disputes).

Practical advice:

• Keep both citizenships documented and up to date (passports, birth certificates, etc.).
• Stay informed about tax filing requirements and deadlines in both countries.
• Seek professional advice if you’re unsure about your family’s obligations or rights.
