Canada Citizenship by Descent Changes Take Effect Under Bill C-3
The Canada citizenship by descent changes officially took effect on December 15, 2025, following the passage of Bill C-3, An Act to amend the Citizenship Act. According to the Government of Canada, the legislation modifies the long-standing first-generation limit on citizenship by descent, expanding eligibility in specific circumstances for people born or adopted outside Canada.
The policy update represents a significant shift in how Canadian citizenship is transmitted across generations and follows earlier court rulings that found aspects of the previous framework to be unconstitutional.
What Changed Under the Canada Citizenship by Descent Changes
Before Bill C-3, Canadian citizenship by descent was generally limited to the first generation born outside Canada. This meant that individuals born abroad to a Canadian parent who was also born outside Canada were typically not considered citizens.
The amendments introduced by Bill C-3 remove this first-generation limit in certain situations. Officials confirmed that eligible individuals in the second generation or beyond may now be recognized as Canadian citizens, provided specific conditions related to parental connection to Canada are met.
The government stated that the change does not affect individuals who were already recognized as Canadian citizens before Bill C-3 became law.
Background and Policy Context
Canadian citizenship rules are governed by the Citizenship Act, which outlines how citizenship is acquired by birth, descent, or naturalization. The first-generation limit was introduced to ensure a meaningful connection to Canada for citizens born abroad.
In December 2023, the Ontario Superior Court of Justice ruled that aspects of the first-generation limit were unconstitutional for certain groups. In response, the federal government introduced interim measures while legislative amendments were developed. Bill C-3 formalizes those changes and establishes a revised legal framework for citizenship by descent.
Under the updated approach, generations are counted based on the first person born or adopted outside Canada to a Canadian citizen. The amendments also clarify how these rules apply to adopted persons seeking citizenship through a direct grant.
Who Is Affected by the Canada Citizenship by Descent Changes
The updated rules affect:
- Individuals born outside Canada in the second generation or later
- People adopted abroad by Canadian parents, depending on generational circumstances
- Individuals born or adopted before December 15, 2025, whose citizenship status may now be recognized automatically
- Applicants whose files were submitted under the interim measures announced after the 2023 court decision
Government guidance indicates that applications submitted under interim measures and still in progress will be assessed under the new rules without requiring a new application.
