For decades, a quiet rule cut millions of people off from a citizenship their families once held. A 2025 law called Bill C-3 changed that—and in doing so opened a realistic path to Canadian citizenship by descent for a large number of people of French-Canadian and other Canadian ancestry, including many Americans whose families came south from Québec generations ago. This guide explains, in plain language, how citizenship by descent now works, who may qualify, and what it takes to prove a claim. It is general information, not legal advice, and the rules are still settling, so treat it as a starting point for your own research and professional consultation.
Important: This article is general information, not legal advice, and we are not lawyers. Canadian citizenship rules changed recently and remain in flux—the documentary standard was tightened during a review in June 2026—and eligibility is determined individually by Immigration, Refugees and Citizenship Canada (IRCC). Always confirm the current rules on the official canada.ca website, and consult a licensed Canadian immigration lawyer or a Regulated Canadian Immigration Consultant (RCIC) about your own situation.
What “citizenship by descent” means
Citizenship by descent is the principle that citizenship can pass from parent to child even when the child is born outside the country. Many people who qualify are not applying to become citizens at all—they already are citizens by operation of law and simply need a document, a citizenship certificate, to prove it. That distinction matters: a proof-of-citizenship application asks IRCC to confirm a status you may already hold, not to grant you something new.
What Bill C-3 changed
Between 2009 and late 2025, Canada applied a “first-generation limit”: a Canadian citizen who was themselves born abroad generally could not pass citizenship to a child also born abroad. That cutoff stranded countless families. In December 2023 an Ontario court found the limit unconstitutional, the government chose not to appeal, and Parliament responded with Bill C-3, which received Royal Assent in November 2025 and came into force on December 15, 2025.
The headline effect: for people born abroad before December 15, 2025, the first-generation limit is removed, so citizenship can now flow down through multiple generations born outside Canada, provided there is an unbroken chain back to a Canadian “anchor” ancestor. The people this restores are often called the Lost Canadians.
The December 15, 2025 dividing line
Your date of birth determines which rules apply to you:
- Born before December 15, 2025: if you descend, through an unbroken chain, from a Canadian-citizen ancestor, you may already be a citizen under the restored rules—with no residency requirement to satisfy. You apply for a certificate to confirm it.
- Born on or after December 15, 2025: a going-forward “substantial connection” test applies. A Canadian parent who was themselves born abroad must have accumulated at least 1,095 days (three years) of physical presence in Canada before the child’s birth for citizenship to pass.
Most people researching their roots fall into the first group, where the question is one of proof rather than residency. To work out where you stand, see am I a Canadian citizen?

Who may qualify through French-Canadian roots
Here is where genealogy and citizenship meet. If your family is Franco-American—descended from the great migration of Québécois to New England—you may have a Canadian-born ancestor close enough in your tree to serve as the anchor. The same is true for many people across the United States and beyond whose families left Canada generations ago. Whether a specific line qualifies depends on each ancestor’s citizenship status under the law as it stood at the time, which is exactly why building an accurate, documented family tree is the first practical step.
The process, in outline
- Build and document the chain. Establish an unbroken line from yourself back to a Canadian-citizen ancestor, with a vital record for every link.
- Apply for a proof-of-citizenship certificate. The application (the citizenship certificate / proof-of-citizenship form on canada.ca) asks IRCC to confirm your status. The government fee has been CAD $75 per person.
- Wait for processing. IRCC has quoted roughly 9 to 12 months, with the new law sharply increasing volumes.
- Use your certificate. Once confirmed, the certificate is your proof of citizenship and the basis for a Canadian passport.
Form numbers and fees change, so always take the current version from canada.ca rather than from any third-party page, including this one.
The documents are everything
A June 2026 review made one lesson unmistakable: the strength of your documentation is the whole game. IRCC asked a number of recent recipients to surrender certificates for re-examination, citing files that relied on genealogy-website records rather than documents from “original source authorities,” without an explanation for any missing originals. Most of those files were subsequently revalidated, and Bill C-3 eligibility itself never changed—but the episode showed that a claim must be built on properly sourced records. We cover exactly what to gather in documents for Canadian citizenship by descent.
A citizenship-by-descent claim stands or falls on its records chain—and the June 2026 review showed IRCC wants documents traceable to original source authorities, not just genealogy-site scans. Use Généalogie Québec (LAFRANCE + Drouin) or Ancestry to locate every Québec vital record in your line, then order certified copies from the official registrar to make the chain defensible. Our records guide explains how.
A note on French citizenship
People sometimes hope that French-Canadian roots open a door to French citizenship as well. In almost all cases they do not—descending from a New France settler is far too distant for French nationality by descent. We explain why in French citizenship and New France ancestry.

Frequently asked questions
Do I have to move to Canada or pay Canadian taxes?
No. Citizenship by descent confirms a status; it does not require you to relocate, and Canadian tax residency generally depends on living in Canada, not on holding citizenship. Still, dual status has tax-filing implications—consult a cross-border tax professional.
Is this a fast track or a lottery?
Neither. It is recognition of a right the law had blocked. There is no draw and no guarantee; eligibility turns on your specific lineage and is confirmed by IRCC based on your documents.
How long does it take?
IRCC has quoted roughly 9 to 12 months for proof-of-citizenship applications, though the surge in applications under the new law is pushing waits toward the longer end. Check canada.ca for current processing times.
The dual-citizenship reality check
Before pursuing a claim, weigh what a second citizenship actually means for you. Canada permits dual citizenship, and being recognized as Canadian does not require giving up another nationality or moving to Canada. But holding two citizenships carries obligations—most importantly, U.S. citizens face ongoing tax-filing and reporting requirements regardless of where they live, and dual status can complicate both. None of this is a reason not to claim a citizenship that is rightfully yours; it is a reason to go in informed, ideally after a conversation with a cross-border tax professional alongside your immigration advice.
The bottom line: Bill C-3 reopened a real door for many people of French-Canadian descent, and the path is one of proof, not relocation or testing. Establish your documented chain to a Canadian ancestor, build it to the source-authority standard the 2026 review made clear, confirm the current rules on canada.ca, and get a professional opinion. The genealogy and the citizenship case are, conveniently, the same project.
