Canadian citizenship by descent: what Americans and Europeans need to know about Bill C-3

By Amir Ismail, RCIC #R412319

Last Updated: April 2026

A law passed in December 2025 may have already made you Canadian

If you have a Canadian ancestor and were born before December 15, 2025, you may already be a Canadian citizen. Not potentially eligible. Not on a path to something. Already a citizen, by operation of law.

Bill C-3, enacted on December 15, 2025, retroactively grants Canadian citizenship to descendants of Canadian citizens across unlimited generations. All you need is an unbroken documentary trail connecting you to a Canadian-born or naturalized ancestor.

You do not need to live in Canada. You do not need to give up your current citizenship. As of March 2026, nearly 48,000 applications are pending at IRCC, and estimates put the number of eligible Americans at up to 3 million. Over 570,000 more people globally outside the US are thought to qualify.

Most of them have no idea.

What the first-generation limit was, and why Canada scrapped it

The 2009 rule that created “Lost Canadians”

Before Bill C-3, Canadian citizenship had a hard cutoff. Under Bill C-37, passed in 2009, a Canadian citizen who was born outside Canada could not pass their citizenship to a child also born abroad. This “first-generation limit” meant that children born to Canadian expatriates had no claim to the citizenship of a parent they might know, love, and identify with.

The result was a group of people now called “Lost Canadians.” Some were children of Canadians working abroad. Some had lived in Canada for years before their parents relocated. A few were rendered stateless. All had their ancestral ties erased by a single line in the law.

The 2023 court ruling that struck it down

In December 2023, the Ontario Superior Court decided Bjorkquist et al. v. Attorney General of Canada and ruled the first-generation limit unconstitutional. The court found it violated Section 15 of the Canadian Charter of Rights and Freedoms. It had effectively created a lesser class of citizenship based purely on where a parent happened to be born.

The government chose not to appeal. Parliament drafted remedial legislation through 2024, eventually passing Bill C-3. See IRCC’s announcement when Bill C-3 came into effect for the official record.

Two tracks: which one applies to you

The law creates two distinct categories based on when you were born or adopted.

The retroactive cohort (born before December 15, 2025)

If you were born or adopted outside Canada before the law’s enforcement date, you fall here. This is likely the group reading this article.

For this cohort, the rules are straightforward. There is no limit on how many generations back your Canadian ancestor can be. There is no substantial connection test. You do not need to have lived in Canada, paid Canadian taxes, or even visited. If you can show an unbroken line of descent to a Canadian citizen, citizenship is conferred automatically.

See IRCC’s official Bill C-3 citizenship rules page for the complete statutory details.

The prospective cohort (born on or after December 15, 2025)

If you or your child were born on or after December 15, 2025, different rules apply. Citizenship is still automatic at birth, but only if the Canadian parent can prove a “substantial connection” to Canada: at least 1,095 cumulative days of physical presence in Canada at any point in their lifetime.

The 1,095 days do not need to be consecutive. Tax filings, employment records, school transcripts, and border crossing data all count as evidence. A parent who spent three summers studying in Canada and a year working in Toronto could potentially meet the threshold, even if those stays happened a decade apart.

The American case: up to 3 million people with New England roots

“La Grande Hemorragie” and why it matters today

Between 1840 and 1930, roughly 900,000 French-speaking Canadians left rural Quebec and the Atlantic provinces for the mill towns of New England. Historians call this migration “La Grande Hemorragie.” They settled in Lewiston and Biddeford in Maine, Manchester and Nashua in New Hampshire, and Fall River, Lowell, and Worcester in Massachusetts.

They built churches, formed parishes, and maintained distinct French-Canadian communities for generations. Their descendants, now numbering in the millions, carry that ancestry through family trees that may stretch back four or five generations. Under Bill C-3, every unbroken line in that descent can now produce a claim to Canadian citizenship.

Regional concentrations

A 2026 analysis by CIC News estimated a 1-in-4 chance that any given resident of New England is eligible for Canadian citizenship under the new law. Androscoggin County in Maine, site of the historical “Little Canadas,” has roughly 33% of residents identifying with French or Canadian ancestry.

Maine statewide sits at approximately 20%, as does New Hampshire. Massachusetts has over 235,000 residents who specifically identify as French Canadian. Demographers note the true figure is likely much higher, given intermarriage and surname changes across generations.

Why Americans are acting now

Many Americans watching the current domestic climate want a backup option. A Canadian passport gives the right to live, work, and access social services in Canada without surrendering US citizenship. Canada fully permits dual nationality.

The financial case is just as direct. Canada does not tax based on citizenship. Unlike the United States, which taxes citizens on worldwide income regardless of where they live, Canadian tax obligations are residency-based. An American who obtains Canadian citizenship but stays in the US does not trigger a Canadian income tax liability.

The application fee? $75 CAD.

The European case: a Canadian passport as a mobility tool

The youth mobility advantage

For Europeans, Canadian citizenship is less about political insurance and more about what the passport unlocks. The gap between a US passport and a Canadian one tells the story clearly.

A US passport grants access to working holiday visas in six countries. A Canadian passport grants access to 36, including 28 European nations.

Working holiday access for Canadians

A Canadian citizen under 35 can apply for the UK’s Youth Mobility Scheme and receive an open work permit for up to three years. No employer sponsorship. No skills assessment.

Similar agreements exist with France, Germany, Spain, Italy, and the Netherlands. Ireland offers Canadians a two-year permit, compared to one year for most other nationalities. Australia extends its working holiday age limit to 35 for Canadians, while other nationalities age out at 30.

For a young person in London, Dublin, or Berlin with Canadian ancestry, this is not an abstract benefit. It is the difference between navigating a work visa process and arriving with a valid passport.

Why Europeans have a different motivation

The European cohort is drawn from the 570,000+ individuals outside the US estimated to be globally eligible under Bill C-3. Their Canadian ancestors left generations ago. Many are third- or fourth-generation descendants of people who emigrated from Canada to the UK, Ireland, or continental Europe over the 20th century.

For this group, a Canadian passport is a practical tool. It opens 36 countries for work and travel in ways that no EU or UK passport can match in the other direction.

What documents you need to prove your lineage

Building your chain of documentation

A citizenship by descent application requires proof of an unbroken line of descent from a Canadian citizen. In practice, that means a chain of birth, marriage, and death certificates, one for every generation between you and your qualifying ancestor.

For a three-generation claim, you typically need your own birth certificate, your parent’s birth certificate, your grandparent’s birth certificate showing Canadian birth or naturalization, and marriage certificates wherever surnames changed along the way.

For multi-generational claims going back to the 19th century, this can involve historical records, church registries, and archival documents held by provincial governments in multiple languages.

Where to get Quebec vital records in 2026

Most Americans with Canadian ancestry trace their roots to Quebec and the Atlantic provinces. Quebec’s Direction de l’etat civil holds birth, marriage, and death records from 1994 onward. Older records are held by the Bibliotheque et Archives nationales du Quebec (BAnQ) and Library and Archives Canada.

Following Bill C-3, Quebec’s archival institutions reported a 3,000% increase in requests for vital records within months of the law coming into force. Wait times have extended significantly. Order records early, and order certified copies. IRCC requires certified documentation, not photocopies.

Processing times and what to realistically expect in 2026

Citizenship by descent is conferred automatically by law, but to exercise that citizenship you need a proof of citizenship certificate from IRCC. That requires a formal application.

As of early March 2026, nearly 48,000 applications were waiting for a decision, with processing times running 10 to 11 months. Before Bill C-3 came into force, the average was roughly 9 months. The Parliamentary Budget Officer projected a base-case take-up of 115,000 individuals over five years, but application volumes from the American cohort are already outpacing that estimate.

Apply now rather than later. The backlog is not shrinking.

Why Canadian citizenship by descent cases benefit from working with a regulated consultant

Citizenship by descent applications are more document-intensive than most immigration files. A gap in the lineage chain, a missing marriage certificate, a surname discrepancy across generations, or a document that was not properly certified can result in a rejection or a long delay.

A regulated consultant does not just help you fill out the form. An RCIC reviews your documentary chain before submission, identifies potential gaps or inconsistencies, and manages correspondence with IRCC. For multi-generational claims tracing back to 19th-century Quebec or provincial records in multiple languages, that review matters.

If you think you may qualify, the best first step is a conversation about your specific lineage before you start pulling records together. Start with a Canadian citizenship by descent application review.

Frequently asked questions

Can I claim Canadian citizenship if my grandparent or great-grandparent was Canadian?

Yes, under Bill C-3’s retroactive provisions. If your grandparent or great-grandparent held Canadian citizenship and you were born before December 15, 2025, you can claim citizenship through that line of descent. There is no generational limit for the retroactive cohort, provided you can document the unbroken chain with certified records.

Do I need to live in Canada or give up my current citizenship to apply under Bill C-3?

No to both. Canadian citizenship through descent does not require you to relocate. You keep whatever citizenship you currently hold. Canada permits dual and multiple nationality, and there is no residency requirement for the retroactive cohort.

How do I prove Canadian ancestry if my family records are incomplete or in French?

Start with what you have: birth certificates, family bibles, census records, or church records. Library and Archives Canada and Quebec’s BAnQ hold historical vital records, many in French. An RCIC can assess which records are required, which substitutes IRCC accepts, and how to handle documents in a language other than English.

Does claiming Canadian citizenship affect my US taxes or FATCA obligations?

Canadian citizenship alone does not trigger Canadian tax obligations. Canada taxes based on residency, not citizenship. An American living in the US pays Canadian taxes only if they spend enough time in Canada to be considered a Canadian tax resident. US citizens remain subject to US worldwide income reporting requirements regardless of any other citizenship they hold. For your specific situation, speak to a cross-border tax advisor.

My parent was born in Canada but I was born abroad on or after December 15, 2025. Do I qualify?

Possibly. You fall into the prospective cohort, which means your Canadian-born parent must prove at least 1,095 cumulative days of physical presence in Canada at any point in their lifetime. If your parent lived, studied, or worked in Canada long enough to meet that threshold, your citizenship is conferred automatically at birth.
