Bill C-3: Canada Reforms Citizenship by Descent Rules — What 'Lost Canadians' Need to Know

On December 15, 2025, the Government of Canada passed Bill C-3, a landmark piece of legislation that reforms how citizenship by descent works. For decades, the "first-generation limit" rule meant that Canadians born abroad to Canadian parents could not pass on their citizenship to their own children born outside Canada. Bill C-3 changes this.

What Was the Problem?

Under the old rules, if you were a Canadian citizen born abroad (or became a citizen through parents who were born abroad), your children born outside Canada were not automatically Canadian citizens. This created a class of people often called "Lost Canadians" — individuals with deep ties to Canada who were denied citizenship due to outdated bureaucratic rules.

What Bill C-3 Changes

  • Removes the first-generation limit — The strict cutoff that prevented citizenship from passing beyond one generation born abroad has been eliminated.
  • Emphasizes genuine connections — The new framework introduces a "substantial connection to Canada" test rather than a rigid generational cutoff.
  • Resolves historical cases — Many "Lost Canadians" who were previously denied can now apply for recognition of their citizenship.

Who Does This Affect?

This primarily affects:

  • Canadians living abroad whose children were born in other countries
  • Military families stationed overseas
  • Individuals who discovered they were "Lost Canadians" due to the old rules
  • Families with multi-generational ties to Canada who have lived abroad

What About the Citizenship Test?

Bill C-3 deals with citizenship by descent (citizenship passed from parent to child). If you're applying for citizenship through naturalization (the standard process for permanent residents), the test requirements remain the same:

  • 20 questions, 45 minutes, 75% to pass
  • Based on the Discover Canada study guide
  • Required for applicants aged 18 to 54

Whether you're a new immigrant preparing for naturalization or someone affected by the Bill C-3 changes, understanding Canadian history, government, and values is essential. Start studying by chapter or take a practice test to see where you stand.
