Canadian citizenship by descent
Canadian citizenship by descent is citizenship passed from a Canadian parent to a child born outside Canada, and the rules have just changed under Bill C-3.
Key takeaways
Canadian citizenship by descent is citizenship passed automatically at birth from a Canadian parent to a child born outside Canada. There is no test, oath or physical-presence requirement for the child, so if you qualify you are already a citizen and simply apply for proof of citizenship. A first-generation limit once blocked descent past the first generation born abroad, but Bill C-3 was passed and took effect on December 15, 2025, and now extends it: born before that date, most people are automatically citizens with no test; born on or after it, a substantial-connection test applies instead.

What is Canadian citizenship by descent?
Canadian citizenship by descent is citizenship you receive automatically at birth because of a Canadian parent, even though you were born outside Canada. If at least one of your parents was a Canadian citizen when you were born, whether they were born in Canada or became Canadian by naturalisation here, you may be a citizen by descent. According to IRCC, the descent rules were updated by Bill C-3(source: canada.ca, “Change to citizenship rules in 2025”, in force since December 15, 2025). Importantly, this is information only and not a determination of your status.
Descent is different from a citizenship grant. With a grant, a permanent resident earns citizenship by meeting the Canadian citizenship requirements, physical presence, the citizenship test and the oath. With descent, you do not apply to become a citizen at all: if you qualify, you already are one, and you simply apply for proof of citizenship. As a standard immigration practice we advise on citizenship by descent and by grant, but we do not handle matters before the Immigration and Refugee Board or the courts, we are not affiliated with the government, and we never guarantee an outcome.
| Are you a citizen by descent? | Likely position under the current rules |
|---|---|
| Born abroad; one parent born in Canada | Generally a citizen by descent (first generation born abroad). |
| Born abroad; one parent naturalised in Canada | Generally a citizen by descent (first generation born abroad). |
| Born abroad before Dec 15, 2025; parent was themselves born abroad to a Canadian | Previously blocked by the first-generation limit; in most cases now automatically a citizen under Bill C-3, no test. |
| Born or adopted abroad on/after Dec 15, 2025; parent was themselves born abroad to a Canadian | Citizen only if the parent shows 1,095 days of physical presence in Canada before the birth (the substantial-connection test). |
| Excluded by older citizenship laws (a “Lost Canadian”) | Many are now recognised as citizens, worth checking your status. |
| Born in Canada | Citizen by birth on Canadian soil, descent rules do not apply. |
| Permanent resident, no Canadian parent | Not by descent, this is the citizenship-by-grant route instead. |
What is the first-generation limit?
The first-generation limit was the rule at the centre of most citizenship-by-descent questions. In broad terms, it allowed Canadian citizenship to pass by descent only to the first generation born outside Canada. So a parent who was a Canadian citizen but who was themselves born abroad generally could not pass citizenship automatically to their own child also born abroad. Citizenship effectively stopped at one generation outside the country.
That limit produced hard outcomes for globally mobile Canadian families, children who grew up believing they were Canadian, only to discover they were not recognised. It is the main reason the term Lost Canadians exists, and the main thing Bill C-3 sets out to fix.
How does Bill C-3 change citizenship by descent?
Bill C-3 updates the descent rules so that citizenship can pass beyond the first generation born abroad in certain cases, rather than being cut off automatically by the first-generation limit. The mechanism is a substantial-connection test: broadly, a Canadian parent who was themselves born abroad can pass citizenship to their child born abroad where the parent has a genuine, demonstrable connection to Canada.
The parent must show at least 1,095 daysof physical presence in Canada before the child's birth or adoption (IRCC, December 2025). This matters most for the second generation born abroad and beyond, where the old first-generation limit used to stop citizenship entirely.
Bill C-3 is in force, passed and effective as of December 15, 2025, per IRCC's own confirmation on canada.ca. The practical upshot is that many people who were previously excluded, and many parents planning a child's status, now have a clearer route to Canadian citizenship than they did under the old first-generation limit.
This page is general information, not a legal determination
Is Bill C-3 actually in force?
Yes. Bill C-3, An Act to amend the Citizenship Act (2025), was passed and took effect on December 15, 2025. This is not a proposal working its way through Parliament, or something expected to happen later, IRCC states plainly on canada.ca that the change “officially took effect” on that date and is now the law it applies to every citizenship-by-descent and proof-of-citizenship file. If a relative was told years ago that the first-generation limit blocked them, that answer may no longer be correct.
If you already applied for a citizenship certificate under the interim measure IRCC ran after the 2023 court ruling (see below), you do not need to reapply, IRCC says it will process that existing application under the Bill C-3 rules.
Born before December 15, 2025 vs born on or after: which rules apply to you
The single fact that decides most cases is your birth date relative to December 15, 2025, not just which generation you belong to.
Born abroad before that date to a Canadian parent, you are now, in most cases, automatically a citizen, even as the second generation or later, with no test for your parent to meet. Born or adopted abroad on or after that date, as the second generation or later, a different rule applies: your Canadian parent must be able to show, at the time of application, that they spent at least 1,095 days in Canada before your birth or adoption. That is the substantial-connection test, and it only runs forward from December 15, 2025. The table above already sets out this same before/after split for the exact scenario where it changes the outcome, a parent who was themselves born abroad.
How citizenship-by-descent generations are counted
IRCC counts generations with precise language worth using exactly, loose talk about “second generation” is where most confusion starts. A Canadian citizen is someone born in Canada, or naturalized. First generation is someone born abroad to that Canadian citizen, and is a citizen by descent. Second generation (or later) is someone also born abroad, but to a first-generation person, someone themselves born abroad to a Canadian. The same counting applies to adopted people applying through the direct grant for people adopted abroad.
Worked example: a grandmother born in Toronto is a Canadian citizen. A mother born in London to that grandmother is first generation, a citizen by descent. A child born in London to that mother is second generation, and whether that child is automatically a citizen, or needs the mother's 1,095 days in Canada proven, turns on the child's birth date against December 15, 2025.
Claiming through a grandparent or great-grandparent: how far back can you go
Canadian citizenship by descent can reach a grandparent or a great-grandparent, because Bill C-3 writes no fixed generational ceiling into the law, provided every link in the chain met whichever connection test applied to that link at the time. No rule stops a claim dead at a particular generation.
In practice, going back further gets harder for a documentary reason, not a legal one. IRCC's own application guidance is explicit that a citizenship certificate application needs original documents, birth certificates, naturalization certificates, or their equivalents, for every generation in the chain, not just yours, and that third-party records alone are not enough.
This is where descent files most often stall: not because the applicant isn't a citizen, but because a document from two or three generations back cannot be found, a civil registry with no surviving records, a naturalization certificate lost decades ago, a name spelled differently across certificates. IRCC will accept a written explanation plus proof you tried, but that is a weaker case than the original document.
Before we file a multi-generation application, we map the chain first, who was Canadian, when, and what document proves it, before touching the application. A gap found before submission is a research task; the same gap found by IRCC after submission is a stalled file.
Why the rules changed: the 2009 first-generation limit and the 2023 court ruling
The first-generation limit was not always the law. It arrived on April 17, 2009, inside a wider package meant to fix an older problem, the original Lost Canadians, people who lost citizenship, or never received it, because of gaps in the 1947 Citizenship Act. Those 2009 changes restored or granted citizenship to most of that group, but at the same time the amendment introduced the first-generation limit, cutting off descent past the first generation born abroad. One Lost Canadians problem was solved while a new one was quietly created.
That new problem reached the courts. On December 19, 2023, the Ontario Superior Court of Justice ruled the first-generation limit, as it then stood, unconstitutional for many of the people it affected. The government chose not to appeal, and ran an interim measure while legislation caught up, culminating in Bill C-3 and its December 15, 2025 effective date. Anyone who applied during that interim period does not need to reapply.
Who are the “Lost Canadians”?
Lost Canadians is the informal name for people who believed they were Canadian, or expected to be, but were shut out by past citizenship laws. Some were caught by the first-generation limit; others by older rules about birth abroad, the timing of a parent's citizenship, marriage, or registration deadlines that no longer reflect how families actually live. For many, the loss surfaced only when they tried to get a passport or pass status to their own children.
The significance of the Bill C-3 changes is that a large group of Lost Canadians are now recognised as citizens, or have a clearer path to recognition. If you suspect you might be one, perhaps a parent or grandparent was a Canadian citizen, or you were born abroad and never formalised your status, it is well worth checking, because recognition affects passports, the right to live and work in Canada, and what you can pass to your own children.
How do I confirm or claim citizenship by descent?
You confirm Canadian citizenship by descent by applying to IRCC for a citizenship certificate, the document that proves you are already a citizen and the one Canada requires before it will issue you a passport.
Because descent is automatic, you do not apply to become a citizen, you apply for proof of citizenship, also called a citizenship certificate. This is a secure IRCC document that confirms the status you already hold, and it is what you use to apply for a Canadian passport. The steps below are the typical path; confirm the current forms, fees and processing times on canada.ca, as demand has been high since the rules changed.
- 01
Map your family facts
Identify which parent (or grandparent) was Canadian, where each generation was born, and the key dates of birth, naturalisation and any time spent in Canada.
- 02
Check the current rules
Read IRCC's citizenship-by-descent and Bill C-3 pages on canada.ca to see how the first-generation limit and substantial-connection test apply to your situation.
- 03
Gather documents
Collect birth certificates across generations, your Canadian parent's proof of citizenship, and any records of their physical presence in Canada.
- 04
Apply for proof of citizenship
Submit an application for a citizenship certificate to IRCC, this confirms, rather than grants, your status.
- 05
Receive your certificate
Once issued, your citizenship certificate is your secure proof of status. Build in time, as processing has been stretched by high demand.
- 06
Apply for a passport
With your certificate, you can apply for a Canadian passport and exercise your rights as a citizen.
Proof of citizenship confirms, it does not grant, your status
Cost and processing time for a citizenship certificate
Being a citizen by descent costs nothing, there is no fee to already hold citizenship by operation of law. The cost is for the proof, the fee IRCC charges to review a citizenship certificate application. Fees change, so confirm the current amount directly on canada.ca's fee schedule rather than a figure repeated from an article.
Processing time is worth watching closely, and it moves. Demand for proof-of-citizenship applications has been elevated since Bill C-3 took effect, from newly eligible applicants and from the backlog IRCC is working through under the new rules, so published times can lag real experience. Check the live processing-time tool on canada.ca before planning around a passport renewal or a child's travel document.
What we check before filing is less about the fee and more about avoiding a second round: that every generation has an accepted original document, that a parent's 1,095-day evidence is dated and complete where that test applies, and that names and dates match across every certificate submitted. A clean file usually beats the posted processing time; one IRCC sends back for more evidence resets the clock.
Who should check their citizenship by descent status?
Some people should treat a Canadian citizenship by descent status check as a priority. You are a strong candidate to look into Canadian citizenship by descent if you were born outside Canada to a parent who was Canadian at your birth; if a parent or grandparent was Canadian and you are unsure whether status reached you; if you were previously told the first-generation limit blocked you; or if you have long suspected you might be a Lost Canadian. Being of Canadian descent is not the same as holding Canadian citizenship: status passes only where the law and your family dates line up, and that is exactly what a status check tests.
It also matters if you are planning a family abroad and want to understand whether you can pass Canadian citizenship to a child born outside Canada under the substantial-connection test. In all of these cases, a short assessment of your facts and dates is the fastest way to know where you stand, and what proof you would need to claim it.
There is a practical reason not to wait. Because the descent rules changed under Bill C-3, many people are now applying for proof of citizenship at once, and the citizenship certificate processing time has been stretched as a result. It helps to gather the records that link the generations of your family together early: birth certificates, your Canadian parent's proof of citizenship, and evidence of their time in Canada. The sooner you confirm your status, the smoother your application will be.
Older documents can take time to track down, so starting early is usually the difference between a clean file and a stalled one. Confirm the current processing times on canada.ca before you plan around any deadline, such as an upcoming move, a passport need or a child's birth abroad.

Frequently asked questions
Am I a Canadian citizen by descent?
You may be a Canadian citizen by descent if you were born outside Canada to at least one parent who was a Canadian citizen at the time of your birth, whether that parent was born in Canada or naturalised here. Until recently, a first-generation limit cut this off for many people born abroad to a Canadian parent who was also born abroad. Under Bill C-3 (in force per canada.ca), that limit has been addressed and many previously excluded people are now recognised as citizens. Whether you qualify depends on your exact family facts and dates, so confirm the current rules on canada.ca and book a consultation for an assessment.
What is the first-generation limit?
The first-generation limit was a rule that, in general, only allowed Canadian citizenship by descent to pass to the first generation born outside Canada. In other words, a Canadian who was themselves born abroad could not automatically pass citizenship to their own child born abroad. This rule left many families without status they expected. Bill C-3 changes how the limit works by allowing citizenship to pass beyond the first generation in certain cases, using a substantial-connection test. Confirm the current rules on canada.ca.
What is Bill C-3 and is it in force?
Yes, Bill C-3 is in force. It is the legislation that updates Canada's citizenship-by-descent rules, and per canada.ca it was passed and took effect on December 15, 2025, not merely proposed or awaiting a further step. If you were born abroad to a Canadian parent before that date, you are, in most cases, now automatically a citizen with no test to meet. If you were born or adopted abroad on or after that date as the second generation or later, your Canadian parent must instead show at least 1,095 days of physical presence in Canada before your birth, the substantial-connection test. This page is general information, not a legal determination of your own status, so confirm your exact facts on canada.ca or with an RCIC.
How many generations back can I claim Canadian citizenship by descent?
There is no fixed generational cap written into the law itself, a claim can in principle reach a grandparent or great-grandparent if every generation in the chain, and whichever connection test applies to each link, is actually met. In practice, claims going back further than one generation are limited less by the rules than by documents: IRCC requires an original birth or naturalization certificate (or equivalent) proving citizenship and parentage for every generation in the chain, not just yours. The further back you go, the harder those original documents usually are to locate, which is the real ceiling most families hit.
Who are the Lost Canadians?
Lost Canadians is the informal name for people who believed they were Canadian, or expected to be, but were excluded by past citizenship laws, including the first-generation limit and older rules about birth abroad, parentage and timing. Many Lost Canadians are now recognised as citizens, or have a clearer path to be recognised, following the Bill C-3 changes. If you think you might be a Lost Canadian, it is worth checking, because recognition can affect passports, work and benefits.
How do I prove I am a Canadian citizen by descent?
Citizenship by descent is not granted by an application, if you qualify, you are already a citizen by operation of law. To prove it, you apply to IRCC for proof of citizenship, also called a citizenship certificate. The certificate is a secure document that confirms your status; you can then use it to apply for a Canadian passport. Demand has been high since the descent rules changed, so processing can be slow, check current processing times on canada.ca.
Is citizenship by descent the same as a citizenship grant?
No. Citizenship by descent is automatic citizenship you receive at birth (or by operation of law) because of a Canadian parent, there is no test, no physical-presence requirement and no oath for you. A citizenship grant is the process a permanent resident goes through to become a citizen, which does involve physical presence, the citizenship test and the oath. If you are a citizen by descent, you simply apply for proof of citizenship rather than going through the grant process.
Does citizenship by descent affect dual citizenship?
Canada permits dual (and multiple) citizenship, so being recognised as a Canadian by descent does not, on Canada's side, require you to give up another nationality. However, your other country may have its own rules, some nations restrict dual citizenship, so confirm with that government. Note that, once recognised, a dual citizen generally needs a valid Canadian passport to board a flight to or from Canada.
Can I get Canadian citizenship by descent through a grandparent?
Possibly, and it now depends heavily on dates. If you were born abroad before December 15, 2025, to a parent who was themselves born abroad to your Canadian grandparent, you are, in most cases, now automatically a citizen under Bill C-3, with no test to meet. If you were born or adopted on or after that date, your parent must instead show at least 1,095 days of physical presence in Canada before your birth, the substantial-connection test, for the claim through your grandparent to succeed. Either way, IRCC will want original documents proving citizenship and parentage for your grandparent and your parent, not just for you. Confirm the current rules on canada.ca and book a consultation.
Is 'born before 2009' the same as 'born before December 15, 2025'?
No, and mixing these two dates up is a common source of confusion. April 17, 2009 is when the first-generation limit was introduced, the rule that first cut off descent past one generation born abroad. December 15, 2025 is when Bill C-3 took effect and changed that limit again. Someone born before 2009 may be affected by the older 2009 and 2015 Lost Canadians provisions; someone born before December 15, 2025 is affected by the newer Bill C-3 split described above. The two dates answer different questions, so check which one is relevant to your situation on canada.ca rather than assuming.
How long does a Canada citizenship by descent application take?
IRCC published about 33 months for a proof of citizenship application on 3 September 2026, against about 12 months for a citizenship grant. Descent files sit at the slower end, because they turn on records from earlier generations.
Can a Regulated Canadian Immigration Consultant help with citizenship by descent?
Yes. As a standard immigration practice, an RCIC can assess whether your family facts likely make you a citizen by descent under the current rules, explain how the first-generation limit and Bill C-3 apply to your case, and prepare and review your proof-of-citizenship application. We do not handle matters before the Immigration and Refugee Board or the courts, we are not affiliated with the government, and we never guarantee an outcome.
