Bill C-3 Explained

How Canada opened citizenship by descent to unlimited generations — and what it means for you.

Timeline

Pre-2023

First-Generation Limit (FGL) era

Pre-2023

The Citizenship Act restricted citizenship by descent to only the first generation born abroad. Children of a Canadian citizen born outside Canada could claim citizenship, but their children could not. This cut off millions of people with deeper Canadian ancestry.

Dec

Bjorkquist Decision

Dec 2023

A court ruling found the first-generation limit unconstitutional. The federal government introduced the Bjorkquist Interim Measure to allow beyond-first-generation applicants to apply while Parliament drafted a permanent fix.

Dec

Bjorkquist Interim Measure

Dec 2023 – Dec 2025

Thousands of people applied under the interim measure. These applications are all valid and are being processed under the final law.

Dec

Bill C-3 takes effect

Dec 15, 2025

Bill C-3 permanently eliminates the first-generation limit. Anyone with a qualifying Canadian ancestor is deemed a citizen from birth, retroactively. The law also introduced the "substantial presence test" for children born outside Canada on or after this date.

Before vs. After Bill C-3

AspectBefore C-3After C-3
Generational limitFirst generation onlyNo known limit (Gen 9+ approved)
Great-grandchild eligibilityNot eligibleEligible
Residency requirementNone (for births abroad)None (for births before Dec 15, 2025)
Post-Dec 15, 2025 births abroadN/ASubstantial presence test applies (1,095 days)
Citizenship "grant" requiredYes (for second gen+)No — citizenship is deemed from birth

Who Counts as Gen 0?

"Gen 0" is the last person in your line who was Canadian — the anchor of your citizenship claim. They must meet one of these four criteria:

  • 1Born in Canada or Newfoundland
  • 2Granted Canadian citizenship after 1946 and before the next generation was born
  • 3Naturalized as a British subject in Canada before 1947
  • 4An Irish citizen or British subject "ordinarily resident" in Canada on January 1, 1947 (or Newfoundland on April 1, 1949)
Practical simplification: Under C-3's current interpretation, if your ancestor was born in Canada, you are almost certainly a citizen. Most historical nuances no longer block eligibility.

The Substantial Presence Test

Bill C-3 introduced a new requirement for children born outside Canada on or after December 15, 2025. The Canadian parent passing citizenship must have spent at least 1,095 cumulative days (about 3 years) physically in Canada before the child was born.

  • Days do not need to be consecutive
  • Any time physically present in Canada counts
  • If the child was born inside Canada, this test does not apply
  • If you were born before December 15, 2025, this test does not apply to you at all

What Does NOT Break the Chain

Ancestor never got a citizenship certificatedoes NOT break the chain
Ancestor naturalized as a US citizendoes NOT break the chain
Taking the US citizenship oathdoes NOT break the chain
Ancestor died before applyingdoes NOT break the chain
You never lived in Canadadoes NOT break the chain
You never visited Canadadoes NOT break the chain

What DOES Break the Chain

Formal adult renunciation of Canadian citizenship in writing to Canadian officials
Adoption — adoptees need a separate "grant of citizenship" process (not citizenship by descent)
