Adopted by a Canadian citizen? Here’s how citizenship by descent works for you

Bill C-3 removed the former first-generation limit for some people born or adopted before December 15, 2025.

As a result, some adopted people who were previously unable to inherit Canadian citizenship through a Canadian ancestor now qualify.

That said, the process works differently than it does for biological children.

This article explains how Canadian citizenship by descent applies to cases of adoption.

Adoption follows a different citizenship process

Under Bill C-3, many biological children born outside Canada before December 15, 2025 who can trace their lineage to a Canadian ancestor are now Canadian citizens automatically. They do not need to take an oath or meet any residency requirements. Instead, they apply for a Canadian citizenship certificate to prove their status.

However, a person adopted abroad by a Canadian citizen generally does not become a Canadian citizen automatically once the adoption process is finalized.

Instead, an adopted person born abroad can become a Canadian citizen through one of two routes:

• A direct grant of citizenship under the adoption provisions of the Citizenship Act; or
• Naturalization after first becoming a Canadian permanent resident.

Adopted people who are born abroad cannot directly for a citizenship certificate. However, once their citizenship grant is approved, they can apply for a Canadian citizenship certificate as proof of their status.

Option 1: Citizenship by direct grant for adopted people

An adopted person born outside Canada may qualify for a direct grant of citizenship.

In general, at least one adoptive parent must have been a Canadian citizen when the adoption took place and must have been eligible to pass on citizenship.

Option 2: Citizenship through naturalization

An Canadian parent may instead sponsor an adopted child to immigrate to Canada as a permanent resident.

Once the child becomes a permanent resident, depending on the their circumstances, a parent or guardian may apply for citizenship for the minor, or the person may later apply as an adult if they meet the adult citizenship requirements. This route is known as citizenship through naturalization.

Before granting citizenship, Immigration, Refugees and Citizenship Canada (IRCC) looks at:

• Whether the Canadian parent is eligible to pass on citizenship; and
• Whether the adopted person meets the requirements for citizenship by adoption.

IRCC also considers factors such as the age of the adopted person and whether the adoption established a genuine parent-child relationship.

For an adopted child under 18 to qualify for a grant of citizenship, the adoption must:

• Be in the child's best interests;
• Create a genuine parent-child relationship;
• Comply with the adoption laws of both the country where the adoption took place and the country where the adoptive parent lives;
• Not have been entered into primarily to gain citizenship or immigration status; and
• Not circumvent the legal requirements that normally apply to international adoptions.

Frequently asked questions

Can an adopted child automatically become a Canadian citizen by descent thanks to Bill C-3?

No. Unlike a biological child born abroad, an adopted child does not automatically become a Canadian citizen when the adoption is finalized. In most cases, their application for Canadian citizenship through the adoption process must be approved. Once that citizenship grant is complete, the individual can obtain a Canadian citizenship certificate as proof of their citizenship.

If my ancestor was adopted by a Canadian family decades ago, am I automatically a Canadian citizen thanks to Bill C-3?

Your adopted ancestor would first need to obtain Canadian citizenship through the adoption provisions of the Citizenship Act. This requires establishing that at least one adoptive parent was a Canadian citizen at the time of adoption and met all of IRCC's requirements for citizenship by adoption.

If the adopted person becomes a Canadian citizen through the adoption provision, descendants (like you) may have a citizenship claim.

I'm a Canadian citizen by descent and have a stepchild. Does my stepchild automatically become a Canadian citizen?

A stepchild does not acquire citizenship through a stepparent by descent unless there is a qualifying legal adoption or another independent citizenship basis.

Another option may be family class sponsorship. Family class sponsorship may be an option if the stepchild qualifies as a dependent child, including as your spouse or partner’s biological or adopted child, and you meet admissibility and other program requirements.

Because citizenship by adoption depends on the circumstances of the adoption and the Canadian parent's citizenship history, eligibility can vary significantly from one family to another. This is especially true for cases involving a longer ancestral chain combined with an adoption, where the answer often turns on adoption dates and parental documentation.

Keep in mind that adoptions are among the more complex proof of citizenship cases. If you're unsure whether you or your child qualifies, consider speaking with a licensed Canadian immigration lawyer or consultant before applying.
