Bill C-3 Citizenship by Descent: Who Qualifies in 2026 (Full Eligibility Rules)
As of May 25, 2026.
Acronyms used in this guide: FGL (First-Generation Limit), Immigration, Refugees and Citizenship Canada (IRCC), CIT 0001 (Application for a Citizenship Certificate), CIT 0014 (Document Checklist), Permanent Residence (PR), jus sanguinis (Latin: "right of blood," citizenship by descent), jus soli (Latin: "right of soil," citizenship by birthplace).
Most Bill C-3 explainers oversimplify the eligibility rules. The actual law has multiple cutoff dates, an exception for post-December-2025 births, retroactive provisions for Lost Canadians, and edge cases for adoption, pre-1947 births, and women who lost citizenship by marriage. This guide walks through every eligibility branch with the exact statutory test, so you can determine whether your specific case qualifies before paying the $75 CAD application fee.

Who is eligible for citizenship by descent under Bill C-3?
The eligibility test is a chain: each link must be documented. The chain runs from any Canadian-citizen ancestor down to you, parent-to-child, with no skipped generations. Under Bill C-3, the First-Generation Limit (FGL) is abolished for births before December 15, 2025, meaning there is no cap on how many generations back the ancestor can be. For births on or after December 15, 2025, the Canadian-citizen parent must have accumulated 1,095 cumulative days of physical presence in Canada before the child's birth or adoption, which is the "substantial connection" test. Pre-1947 births fall under earlier Citizenship Acts, and Bill C-3 closes most gender-based gaps left open by Bill C-37 (2009) and Bill C-71 (2014). Adoption qualifies, but only through IRCC's recognized adoption-by-grant process. The IRCC eligibility tool is free and worth running before applying.
What is the legal test for citizenship by descent, in plain English?
Short answer: You are a Canadian citizen under Bill C-3 if (a) you were born outside Canada, (b) you can document an unbroken parent-to-child line back to a Canadian-citizen ancestor, (c) the ancestor was a Canadian citizen at the time the next-generation child was born, (d) you were born before December 15, 2025, or if born after that date, your Canadian-citizen parent had accumulated 1,095 days of physical presence in Canada before your birth.
The statutory authority is section 3 of the Citizenship Act, R.S.C. 1985, c. C-29, as amended by An Act to amend the Citizenship Act (2024), S.C. 2024, c. 17. The amending Act came into force December 15, 2025. The key operative test reads (paraphrased):
A person is a citizen if they were born outside Canada to a parent who was a Canadian citizen at the time of the birth, regardless of which generation of descent the birth represents, unless the birth occurred on or after December 15, 2025 and the Canadian parent does not meet the substantial-connection requirement of 1,095 cumulative days of physical presence in Canada before the birth.
Four moving parts:
- Born outside Canada. Bill C-3 is about citizenship by descent. If you were born inside Canada, you are a citizen by jus soli under section 3(1)(a) of the Citizenship Act; Bill C-3 doesn't change anything for you. Birth tourism limitations don't apply: if you were born on Canadian soil, regardless of your parents' status, you're a citizen.
- Parent was a Canadian citizen at the time of your birth. Not "of Canadian ancestry," not "born in Canada." A Canadian citizen at the time of your birth. This is the most-misunderstood phrase in the test. If your grandfather was born in Halifax in 1910 but became a U.S. citizen in 1945 and renounced his Canadian citizenship before your father was born in 1948, the line is broken at your father, as your grandfather was not a citizen at the time of your father's birth.
- Unbroken line. No skipped generations. If you're claiming through a great-grandparent, you must document the great-grandparent → grandparent link AND the grandparent → parent link AND the parent → you link.
- Cutoff date. Born before December 15, 2025 → the unbroken descent rule applies regardless of generation count. Born December 15, 2025 or later → the Canadian-citizen parent must have 1,095 days physical presence in Canada before the birth.
Which four eligibility branches does Bill C-3 recognize?
Short answer: Most Bill C-3 applicants fall into one of four categories: (1) born to a Canadian-citizen parent abroad, second generation or further; (2) Lost Canadian whose status was previously stripped by FGL; (3) child whose Canadian parent was born abroad (pre-existing FGL applied to them); (4) adult adoptee or descendant adopted by a Canadian citizen. The eligibility map below covers all four.
The four branches below run in order of frequency. Most readers will find their case in Branch 1 (multi-generational descent) or Branch 2 (Lost Canadian restoration). Adoption cases belong in Branch 3. If the relevant birth occurred on or after December 15, 2025, go directly to Branch 4, which applies a different eligibility test.
Branch 1: Second-generation or further descent
You are the grandchild, great-grandchild, or further descendant of a Canadian citizen. Your parent and possibly grandparent(s) were also born outside Canada. Under the pre-Dec 2025 FGL, you would have been excluded after the first generation born abroad. Bill C-3 removes that cap.
[TABLE]
| Generation | Born in Canada? | FGL pre-Dec 2025 applied? | Bill C-3 (post-Dec 2025) status |
|---|
| Great-grandparent (Generation 0) | Yes (or naturalized in Canada) | N/A | Original Canadian citizen |
| Grandparent (Generation 1) | Born in U.S. | Citizenship inherited (first generation born abroad; allowed) | Citizen |
| Parent (Generation 2) | Born in U.S. | EXCLUDED by FGL | Citizen retroactively |
| You (Generation 3) | Born in U.S. | EXCLUDED by FGL | Citizen retroactively (if you were born before Dec 15, 2025) |
If everyone in the chain was alive on December 15, 2025, they all became Canadian citizens on that date. If a generation member died before that date, the line still descends; death does not break the chain provided the deceased was a Canadian citizen (under Bill C-3's retroactive operation) at the time of their child's birth.
Branch 2: Lost Canadians whose status was previously stripped
"Lost Canadians" refers to people whose Canadian citizenship was either (a) never granted because of FGL or (b) stripped by historical citizenship rules (pre-1947 born-in-wedlock-to-Canadian-mother provisions, pre-1977 oath requirements, etc.). Bill C-3, along with its predecessors Bill C-37 (2009) and Bill C-71 (2014), has restored citizenship to most of these people. Bill C-3 closes the remaining gaps left open by FGL.
You are a Lost Canadian eligible for restoration if:
- You were born abroad to a Canadian-citizen parent who themselves was born abroad (the classic FGL exclusion).
- You renounced or were deemed to renounce Canadian citizenship before age 28 under the old section 8 of the Citizenship Act (which has since been repealed).
- You are the child of a Canadian-citizen mother born abroad before 1947 who was excluded under gender-discriminatory rules in the 1947 Canadian Citizenship Act.
For most Lost Canadians, the application is the same Form CIT 0001. There is no separate "restoration application." Your citizenship is restored automatically by operation of law on Dec 15, 2025; the certificate is just the paper proof.
Branch 3: Adopted by a Canadian citizen
Adoption qualifies for citizenship by descent under section 5.1 of the Citizenship Act, but only if the adoption was completed through one of IRCC's recognized adoption-by-grant or adoption-by-direct-grant processes.
[TABLE]
| Adoption type | Bill C-3 implication |
|---|
| Hague Convention international adoption with IRCC adoption-by-grant process | Adoptee qualifies for citizenship by descent; Bill C-3 removes FGL on subsequent generations |
| State-law adoption in the U.S. without IRCC adoption-by-grant | Does NOT confer Canadian citizenship; adopted descendants do NOT qualify |
| Adoption of an adult by a Canadian-citizen adoptive parent | Recognized in most cases if the adoption is legally valid in both jurisdictions |
| Step-parent adoption without independent IRCC process | Does NOT confer Canadian citizenship on its own |
If your line passes through an adopted ancestor, IRCC will require the adoption-by-grant documentation as part of the genealogy chain. This is one of the more complex eligibility branches and benefits most from a Regulated Canadian Immigration Consultant (RCIC) review.
Branch 4: Post-Dec 15, 2025 births and the 1,095-day rule
If you were born on or after December 15, 2025, you do NOT qualify on the unbroken-descent rule alone. The Canadian-citizen parent who gave you citizenship by descent must have accumulated 1,095 cumulative days (3 years) of physical presence in Canada before your birth or adoption.
The 1,095-day standard mirrors the residency test for naturalization. "Physical presence" is counted strictly: days inside Canadian borders. Day of entry and day of departure both count. Travel through Canadian airports on connecting flights does NOT count.
[TABLE]
| Scenario | Qualifies under Bill C-3? |
|---|
| Canadian parent born and raised in Toronto, never lived outside Canada → child born in U.S. in 2027 | Yes (parent had 18+ years of physical presence) |
| Canadian parent born abroad to grandparents who were Canadian citizens; parent visited Canada for 30 days total → child born in U.S. in 2027 | No (parent did not meet 1,095-day rule) |
| Canadian parent born abroad to Canadian-citizen grandparents; parent moved to Canada at age 21 and lived there 4 years before moving back to U.S. → child born in 2027 | Yes (parent accumulated more than 1,095 days) |
| Canadian parent who is in the U.S. military stationed in Canada for 6 years → child born during Canadian assignment | The 6 years count as physical presence; child qualifies |
The 1,095-day requirement is per-parent, not per-family. If only one of two parents is Canadian, only that parent's days are counted.
How does Bill C-3 handle pre-1947 births and historical edge cases?
Short answer: Bill C-3 closes most gaps left by earlier reforms, but some pre-1947 cases involve overlapping historical statutes. If your line passes through a Canadian-born grandmother who married a non-Canadian before 1947 (and was deemed under the old law to have lost citizenship by marriage), her descendants, including you, may now qualify. The retroactive operation reaches back further than most people expect.
Canada's citizenship law has been amended in major waves. Each wave covered slightly different historical gaps:
[TABLE]
| Statute | Year | What it did |
|---|
| Canadian Citizenship Act | 1947 | Created standalone Canadian citizenship for the first time. Before this, "Canadians" were British subjects |
| Citizenship Act, 1977 | 1977 | Replaced the 1947 Act; removed many gender-based discriminatory rules |
| Bill C-37 | 2009 | Restored citizenship to many "Lost Canadians" including pre-1977 oath-requirement exclusions |
| Bill C-71 | 2014 | Further restoration; closed gender gaps in the 1947 Act |
| Bill C-3 | 2024 (in force 2025) | Removed the First-Generation Limit; closed remaining FGL gaps |
If your ancestor's case sits at the seam between two statutes (e.g., a 1944 birth to a Canadian father, or a 1946 marriage that deemed a Canadian-born woman to have lost citizenship), the question of "was she a Canadian citizen at the time of her child's birth" requires a statute-by-statute analysis. The good news: Bill C-3 is broad enough that most pre-1947 gaps are now closed by retroactive operation. The bad news: documenting it is harder because civil records from 1900-1950 are often incomplete or held in provincial archives.
For these cases, hire a genealogist or work with an RCIC who specializes in historical citizenship work before submitting CIT 0001.
What disqualifies you from citizenship by descent under Bill C-3?
Short answer: Some people are excluded from Bill C-3 even with a clean Canadian ancestry chain. The two main exclusions are: (1) prior renunciation of Canadian citizenship that has not been revoked, and (2) revocation for fraud (e.g., the historical "citizens of convenience" exclusion). A criminal record by itself does NOT disqualify you from proof of citizenship. The citizenship-by-descent path is rights-based, not discretionary.
Specific disqualifying factors:
- You voluntarily renounced Canadian citizenship under section 9 of the Citizenship Act and have not had the renunciation reversed. This is rare: renunciation requires a deliberate application and is rarely reversed.
- Your citizenship was previously revoked for misrepresentation or fraud. A specific revocation order against you is binding; you cannot simply re-apply.
- You are excluded under specific war-crimes or terror-related provisions of the Citizenship Act. These exclusions are narrow and rarely apply to ordinary applicants.
Things that do NOT disqualify you:
- A U.S. criminal record (provincial public health and certain federal benefits may have different rules, but citizenship itself is not affected).
- Your U.S. citizenship status (Canada permits dual citizenship).
- Your immigration history with IRCC (a refused TRV or work permit does not affect a citizenship-by-descent claim).
- Your political activities, religion, marital status, or sexual orientation.
- The fact that you never set foot in Canada (Bill C-3 explicitly contemplates citizenship by descent for U.S.-resident descendants).
How do you confirm your Bill C-3 citizenship eligibility before applying?
Short answer: Run IRCC's free Am I a Canadian citizen tool before paying the application fee. The tool walks you through a series of yes/no questions about your birthplace, your parents' birthplaces, and your ancestors' citizenship status. It does NOT replace Form CIT 0001, but it gives you a free preliminary answer in 15 minutes and tells you exactly which documents you'll need.
The IRCC tool's logic flow:
- Were you born inside Canada? → If yes, you're already a citizen.
- Were you born outside Canada? → Continue.
- Was at least one of your biological or legal-adoption parents a Canadian citizen at the time of your birth? → If yes, you may be eligible; collect documents.
- Was that parent ALSO born outside Canada? → If yes, continue to grandparent question.
- Repeat the chain back until you reach someone born or naturalized in Canada.
If the tool concludes "you may be a Canadian citizen," proceed to Form CIT 0001. If it says "you do not appear to be a Canadian citizen," your only path is naturalization through Permanent Residence (PR); read Americans Moving to Canada: 7 Visa Paths for the alternatives.
For complex cases (Lost Canadian, pre-1947, adoption, multiple renunciations in the chain), the IRCC tool may give an inconclusive answer. That's a sign to book a 30-minute RCIC review before applying.
What do people commonly ask about Bill C-3 citizenship by descent?
These questions address specific eligibility scenarios that come up frequently. The answers cover multi-generational descent, historical marriage rules, documentation gaps, and current processing timelines. For any case involving a chain of more than three generations, an adoption in the line, or a prior renunciation, a consultation with an RCIC will give a more precise answer than a general guide.
How many generations can citizenship pass through under Bill C-3?
Unlimited, with one caveat. For people born BEFORE December 15, 2025, there is no cap on generations. A claimant can be the 4th, 5th, or 10th generation born abroad, as long as the unbroken parent-to-child chain back to a Canadian-citizen ancestor is documented. For people born AFTER December 15, 2025, the parent's 1,095-day physical-presence requirement effectively limits the chain at the third or fourth generation in practice, because each generation must have accumulated significant time in Canada.
My grandfather was born in Canada but naturalized in the U.S. before my father was born. Do I qualify?
Probably not, but the answer depends on the timing. The legal test is: was your grandfather a Canadian citizen at the time of your father's birth? If your grandfather had become a U.S. citizen AND formally renounced his Canadian citizenship (under the old law that required renunciation when naturalizing in another country, applicable before 1977), the line breaks at your father. If your grandfather naturalized in the U.S. but never formally renounced his Canadian citizenship, which is common for naturalizations between 1947 and 1977, he may have retained Canadian citizenship under the dual-citizenship-by-omission rule. An RCIC can review the dates and applicable historical statutes to determine which case applies.
My great-grandmother was Canadian, but the line passes through a marriage in 1928. Does that affect eligibility?
Possibly, in your favor. Under the pre-1947 Naturalization Act, women who married non-Canadians were often deemed to have lost their Canadian nationality by operation of law (a gender-discriminatory rule). Bill C-71 (2014) and Bill C-3 (2025) both retroactively restore citizenship to women in these situations and their descendants. If you're claiming through a pre-1947 great-grandmother marriage, you almost certainly qualify under Bill C-3's retroactive operation, even though the chain would have been broken under the rules as they existed at the time.
What documents prove the chain?
For each generation, you need (1) a long-form birth certificate showing both parents' names, and (2) a marriage certificate for any generation where the surname changed (typically the women). For the Canadian-citizen ancestor at the root of the line, you also need proof of their Canadian citizenship at the time of the next generation's birth, most commonly a long-form Canadian birth certificate, but baptismal records (from before centralized civil registration), naturalization certificates, or census records can also work. For pre-1900 ancestors, parish baptismal records from Quebec, New Brunswick, or Ontario are often the only documentary source.
What if a key document is lost or destroyed?
IRCC will accept "best evidence" when a primary record is unavailable. If a courthouse fire destroyed your great-grandparent's birth records, you can substitute (a) the LDS Family History Center's microfilmed copies, (b) a baptismal record from the parish church, (c) census records showing the birth, or (d) sworn statutory declarations from people with personal knowledge. Plan to provide more, not less, documentation when a primary record is missing.
How long does it take to process a Bill C-3 application?
The current service standard for proof of citizenship is 11 months. Bill C-3 surge applications since December 2025 have pushed some files to 12-14 months. There is no expedited processing for ordinary applicants (humanitarian-grounds urgent processing exists but is rarely granted). Plan for a full year between submission and certificate.
Do my children automatically inherit citizenship once I have the certificate?
If your children were born BEFORE December 15, 2025, they are already Canadian citizens by descent through you, and they need their own CIT 0001 to get their own certificates. If your children were born AFTER December 15, 2025, the answer is the 1,095-day rule: you must have accumulated 1,095 days of physical presence in Canada before the child's birth or adoption, OR the child must be born in Canada (in which case jus soli applies regardless).
Can I claim through a great-great-grandparent?
Yes, assuming you can document every generation in between. Bill C-3 doesn't cap generations for pre-Dec 2025 births. The practical limiter is documentary: each generation needs at least a birth certificate and (where surnames change) a marriage certificate. For 5-6 generations back, this is genuinely difficult and often requires professional genealogical research.
What's the difference between Bill C-3 and earlier citizenship reforms?
Bill C-37 (2009) restored citizenship to many Lost Canadians but kept the First-Generation Limit. Bill C-71 (2014) closed remaining pre-1947 gender gaps but also kept the FGL. Bill C-3 (in force December 15, 2025) finally removes the FGL entirely and explicitly handles the post-Dec-2025 cohort with the 1,095-day substantial-connection rule. Bill C-3 is the broadest of the three reforms.
When should you consult an RCIC for a Bill C-3 application?
The simple cases (one or two generations, clean documents, all in English, no historical complications) are well-suited to a DIY application. The complex cases benefit from professional review:
- Pre-1947 chains
- Adoption in the line
- Suspected prior renunciation
- Missing documents in one or more generations
- Mixed nationality chains (e.g., dual American/Canadian/British citizenship somewhere in the line)
- A previously refused proof-of-citizenship application
