Canadian citizenship by descent allows people born outside Canada to a Canadian parent to acquire Canadian citizenship — without immigrating through Express Entry, sponsorship, or any other immigration program. On December 19, 2025, Bill C-3 (An Act to amend the Citizenship Act) came into force, dramatically expanding who qualifies. If you have Canadian ancestry, the rules have changed in your favour.

Calculate feesWhat Is Citizenship by Descent?
Citizenship by descent means acquiring Canadian citizenship through your parent(s) rather than by being born on Canadian soil (jus soli) or through naturalization. Under the Citizenship Act, certain persons born outside Canada to a Canadian parent are Canadian citizens from birth — they don't apply for citizenship, they apply for proof of citizenship they already have.
This is distinct from immigration. A citizen by descent has the same rights as any Canadian citizen — the right to live, work, and vote in Canada, hold a Canadian passport, and pass citizenship to their own children (subject to generational limits).
Bill C-3: What Changed (December 2025)
Bill C-3 (An Act to amend the Citizenship Act) received Royal Assent on June 19, 2024, and came into force on December 19, 2025. It made the most significant changes to citizenship by descent rules in decades:
- Replaced the strict first-generation limit with a more flexible "substantial connection to Canada" test for the second and subsequent generations born abroad
- Retroactively restored citizenship to many "Lost Canadians" who had lost or never acquired citizenship due to previous legislative gaps
- Created a new pathway for persons born abroad in the second or subsequent generation to claim citizenship if a parent had a substantial connection to Canada
- Addressed gender discrimination in pre-1977 citizenship rules — women who lost citizenship by marrying a foreign national can now reclaim it
- Extended citizenship to persons born abroad before 1977 to a Canadian mother who were excluded under the old patrilineal rules
The practical effect: thousands of people — especially Americans with Canadian parents or grandparents — who were previously blocked by the first-generation limit may now be Canadian citizens. For more details, see IRCC's Bill C-3 overview on canada.ca.
"Lost Canadians" — Who Are They?
"Lost Canadians" is an informal term for people who were — or should have been — Canadian citizens but lost their citizenship (or never acquired it) due to gaps and discriminatory provisions in previous citizenship legislation. Common Lost Canadian situations include:
- Persons born abroad to a Canadian mother before 1977 — the old Citizenship Act only transmitted citizenship through the father
- Women who automatically lost Canadian citizenship upon marrying a foreign national before 1977
- Persons born in Canada before 1947 who were British subjects (Canada had no separate citizenship until the 1947 Citizenship Act)
- Second-generation born abroad before April 17, 2009 who failed to retain citizenship by applying before age 28 (old retention rule)
- Children born abroad to Canadian parents who never registered the birth with Canadian authorities
Bill C-3 addressed most of these gaps. If you believe you may be a Lost Canadian, you can apply for a proof of citizenship — the application process will determine whether you are (and may always have been) a citizen.
The First-Generation Limit: Before vs After Bill C-3
Since April 17, 2009, Canadian citizenship by descent was limited to the first generation born abroad. This meant:
| Scenario | Pre-Bill C-3 | Post-Bill C-3 |
|---|---|---|
| Born abroad to a Canadian-born parent | Citizen ✓ | Citizen ✓ |
| Born abroad to a parent who was themselves born abroad to a Canadian | Not a citizen ✗ | May be citizen ✓ (if parent had substantial connection) |
| Born abroad to a naturalized Canadian parent | Citizen ✓ | Citizen ✓ |
| Third generation born abroad | Not a citizen ✗ | Depends on substantial connection test |
The "substantial connection to Canada" test under Bill C-3 considers factors like whether the Canadian parent lived in Canada, maintained ties, or had a genuine connection. This is assessed by IRCC during the proof of citizenship application. Guidance on what constitutes a "substantial connection" is published on canada.ca.
Eligibility: Are You a Canadian Citizen?
Work through this decision tree to determine if you may be a Canadian citizen by descent:
Were you born in Canada?
If yes → you are likely a citizen by birth (jus soli). Apply for proof of citizenship.
Were you born outside Canada to at least one Canadian parent?
If yes → proceed to step 3. If no → you are not a citizen by descent.
Was your Canadian parent born in Canada OR naturalized in Canada?
If yes → you are a first-generation born abroad = Canadian citizen. Apply for proof of citizenship.
Was your Canadian parent themselves born abroad to a Canadian?
You are second generation born abroad. Under Bill C-3 → your parent must have had a "substantial connection to Canada" for you to qualify.
Did your Canadian parent ever live in Canada, maintain ties, or have a genuine connection?
If yes → you may qualify under the Bill C-3 substantial connection test. Apply for proof of citizenship — IRCC will assess. If no → you likely do not qualify.
Were you born before 1977 to a Canadian mother and foreign father?
Bill C-3 retroactively grants citizenship in many of these cases. Apply for proof of citizenship.
How to Apply: Proof of Citizenship
If you believe you are a Canadian citizen by descent, you apply for a proof of citizenship certificate using IRCC form CIT 0001 (Application for a Citizenship Certificate — Adults) or CIT 0002 (for minors). The process:
- 1
Download and complete CIT 0001 or CIT 0002
Available on canada.ca. Complete all sections including parent's citizenship details.
- 2
Gather supporting documents
Birth certificate (yours), parent's Canadian birth certificate or citizenship certificate, proof of parent's identity, and any documents showing substantial connection to Canada (if second generation).
- 3
Pay the government fee
The proof of citizenship application fee is $75 CAD (adults). No right of citizenship fee applies — you are proving existing citizenship, not applying for a grant.
- 4
Submit your application
Mail the completed application and all documents to the IRCC Case Processing Centre in Sydney, Nova Scotia.
- 5
Wait for processing
Current processing times are approximately 5–12 months depending on complexity. Second-generation cases under Bill C-3 may take longer as the substantial connection test is assessed.
- 6
Receive your citizenship certificate
Once approved, you receive a citizenship certificate. You can then apply for a Canadian passport.
Required Documents
Gather the following before submitting your proof of citizenship application:
- Your birth certificate (long form, showing parent names)
- Parent's Canadian birth certificate or citizenship certificate
- Parent's valid or expired Canadian passport (if available)
- Two citizenship photos meeting IRCC specifications
- Government-issued photo ID (current)
- Marriage certificates if name has changed
- For Bill C-3 substantial connection cases: evidence of parent's time in Canada (tax returns, school records, employment records, residential leases, etc.)
- For Lost Canadian cases: any historical documents proving the Canadian connection (immigration records, census records, military records)
- Translation of any documents not in English or French (certified translation)
Processing Times
| Application Type | Estimated Processing |
|---|---|
| First generation born abroad (straightforward) | 5–8 months |
| Second generation (Bill C-3 substantial connection) | 8–15 months |
| Lost Canadian — pre-1977 gender discrimination | 6–12 months |
| Complex/historical cases | 12–18+ months |
Processing times are estimates based on IRCC published data. Check IRCC processing times on canada.ca for current wait times.
Dual and Multiple Citizenship
Canada fully recognizes dual (and multiple) citizenship. Claiming Canadian citizenship by descent does not require you to renounce your current citizenship. Key points:
- You can hold Canadian citizenship alongside US, UK, or any other citizenship
- Canada will not notify your current country of citizenship — your disclosure obligations depend on that country's laws
- As a Canadian citizen, you must enter Canada on a Canadian passport (or with a Canadian travel document)
- Some countries do not recognize dual citizenship — check your country's laws before applying
- US citizens who acquire Canadian citizenship do not lose their US citizenship — the US also allows dual nationality
- Tax implications: Canadian citizens have Canadian tax obligations if they reside in Canada. Simply holding citizenship while living abroad does not create Canadian tax liability (unlike US worldwide taxation)
Americans with Canadian Ancestry
An estimated 2+ million Americans have at least one Canadian-born parent or grandparent. In 2025–2026, interest in Canadian citizenship by descent surged among Americans — driven by political uncertainty and the newly expanded eligibility under Bill C-3.
If you are an American with Canadian ancestry, here's what to check:
- Was a parent born in Canada? → You are very likely a Canadian citizen already. Apply for proof.
- Was a grandparent born in Canada, and did your parent live in Canada? → Under Bill C-3, you may qualify through the substantial connection test.
- Was a parent a Canadian citizen who never lived in Canada? → The substantial connection test may still be met through other ties (property, family, financial connections).
- Do you have a Canadian birth certificate for your parent? → This is the single most important document. Start searching.
Canadian citizenship gives Americans visa-free entry to 185+ countries, access to Canadian healthcare (if resident), and the right to live and work anywhere in Canada.

View ReportsFrequently Asked Questions
Do I need to immigrate to Canada if I'm a citizen by descent?
No. If you are a Canadian citizen by descent, you have the right to enter, live, and work in Canada without any immigration application. You simply need proof of citizenship (a citizenship certificate) and a Canadian passport.
My parent was born in Canada but moved to the US as a child. Am I a citizen?
Very likely yes. If your parent was born in Canada, they are a Canadian citizen regardless of when they left. As a first-generation born abroad, you are a citizen by descent. Apply for proof of citizenship using form CIT 0001.
What is the "substantial connection to Canada" test under Bill C-3?
The substantial connection test applies to second (and subsequent) generations born abroad. IRCC assesses whether your Canadian parent had a genuine connection to Canada — through residence, education, employment, family ties, property, tax filing, or other meaningful ties. Specific guidance is published on canada.ca.
My grandmother was Canadian but my parent was born in the US. Can I claim citizenship?
Under Bill C-3, possibly. Your parent (born abroad to a Canadian) is first-generation born abroad and is a citizen. You would be second-generation born abroad. Your eligibility depends on whether your parent had a substantial connection to Canada. If your parent lived in Canada for any period, maintained ties, or had other connections, you may qualify.
How much does it cost to get proof of Canadian citizenship?
The IRCC government fee for a proof of citizenship (citizenship certificate) is $75 CAD for adults. There is no right of citizenship fee because you are proving existing citizenship, not being granted it. If you subsequently apply for a Canadian passport, that is a separate fee.
Can I pass Canadian citizenship to my children?
If you are a first-generation born abroad (parent born in Canada), your children are second-generation. Under Bill C-3, they may qualify if you have a substantial connection to Canada. If you are a citizen born in Canada, your children born abroad are first-generation and automatically citizens.
Will claiming Canadian citizenship affect my US citizenship?
No. The United States recognizes dual nationality. Acquiring Canadian citizenship does not result in loss of US citizenship. You are not required to renounce one to hold the other. However, you should be aware that as a US citizen, you have worldwide tax obligations regardless of where you live.
How long does the proof of citizenship process take?
Straightforward first-generation cases typically take 5–8 months. Bill C-3 substantial connection cases may take 8–15 months as IRCC assesses the connection evidence. Complex historical cases can take 12–18+ months. Check IRCC processing times on canada.ca for current estimates.
