Canadian citizenship by descent

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, “Citizenship rules: changes to the law”, current to May 2026). 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.

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.

This is typically measured by physical presence in Canada, in the order of 1,095 days, before the child's birth or adoption. This matters most for the second generation born abroad and beyond, where the old first-generation limit used to stop citizenship entirely.

We describe Bill C-3 as in force / current following royal assent in November 2025, but the detailed rules around it have been evolving, so treat the specifics here as a starting point only and confirm the live position on canada.cabefore acting. 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.

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?

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.

1. 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.

2. 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.

3. 03

   Gather documents

   Collect birth certificates across generations, your Canadian parent's proof of citizenship, and any records of their physical presence in Canada.

4. 04

   Apply for proof of citizenship

   Submit an application for a citizenship certificate to IRCC, this confirms, rather than grants, your status.

5. 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.

6. 06

   Apply for a passport

   With your certificate, you can apply for a Canadian passport and exercise your rights as a citizen.

Who should check their status?

Some people should treat a 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.

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 timehas 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.
