Canada implemented Bill C-3, An Act to Amend the Citizenship Act (2025), marking a major reform to how Canadian citizenship is inherited and restoring the rights of tens of thousands of people worldwide who were previously excluded under outdated law. The new law, designed to modernize citizenship rules and better reflect the global reality of Canadian families, came into force on December 15, 2025.

Immigration, Refugees and Citizenship Canada (IRCC) and government leaders describe the amendment as a historic step toward fairness, inclusivity, and clarity. “This new legislation strengthens the bond between Canadians at home and around the world,” said Minister of Immigration Lena Metlege Diab.

What Bill C-3 Does

At its core, Bill C-3 expands who qualifies as a Canadian citizen by descent and corrects longstanding limitations in the Citizenship Act:

Removes the First-Generation Limit (FGL)

Under prior law, citizenship by descent was limited to the first generation born abroad—meaning if a child was born outside Canada to a parent who was also born outside Canada and had gained citizenship by descent, that child could not automatically acquire citizenship. Bill C-3 eliminates that automatic restriction for those born before the Act’s effective date, allowing many individuals formerly excluded to apply for recognition of citizenship.

Substantial Connection Test (Going Forward)

For children born on or after December 15, 2025 outside Canada to parents who themselves were born abroad, citizenship by descent still can be passed on provided the Canadian parent meets a “substantial connection to Canada” requirement. This test generally requires demonstrating at least 1,095 cumulative days (three years) of physical residence in Canada before the child’s birth or adoption.

Bill C-3 Restores Lost Citizenship and Addresses Other Gaps

Bill C-3 also restores citizenship for:

Individuals who lost citizenship due to outdated retention rules in previous versions of the law.
Individuals born abroad who would have been Canadian citizens but for previous statutory limits.

This means many so-called “Lost Canadians” worldwide can now apply for proof of citizenship that recognizes their status retroactively.

Impact and Transition

IRCC will continue to process applications that had already been filed under interim measures in place before the new law took effect, transitioning them to the updated framework without requiring re-submission.

Legal experts predict that tens of thousands of people globally — including large numbers of families in the United States, India, Europe, and elsewhere — will benefit from the broader citizenship eligibility. Bill C-3 has been widely discussed in global diasporic communities, particularly among Indian-origin families with multi-generational ties to Canada.

Why the Change Happened

The push for reform began after the Ontario Superior Court of Justice ruled in December 2023 that the first-generation limit was unconstitutional, as it created unequal treatment of Canadians based on where they were born. The government subsequently introduced Bill C-3, which was deliberated and amended through Parliament before receiving Royal Assent on November 20, 2025.

What This Means for Applicants

Eligible individuals can now apply to IRCC for a Citizenship Certificate, the official proof of Canadian citizenship. This includes those who:

Were born abroad before December 15, 2025 and were previously excluded by the old first-generation limit.
Were born or adopted abroad after this date and whose Canadian parent meets the substantial connection test.
Lost citizenship under earlier laws and now qualify for restoration.

Canadian citizenship offers important rights, including the ability to vote in federal elections, hold a Canadian passport, sponsor family members, and enjoy unrestricted entry and residency in Canada.
