Bill C-3 is the law that reshaped Canadian citizenship by descent at the end of 2025. If you have heard that “millions of people may now be Canadian,” this is the legislation behind the headline. Here is what it actually did, how it came about, and why a turbulent few weeks in June 2026 matter for anyone thinking of applying. As with everything in this section, it is general information rather than legal advice.
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.
The problem Bill C-3 fixed
In 2009, Canada introduced a first-generation limit on citizenship by descent. The rule was blunt: a Canadian citizen who was themselves born outside Canada generally could not pass citizenship to a child who was also born outside Canada. Families with deep but multi-generational ties abroad found the chain simply cut—parents who were Canadian, children who were not, for no reason but where two generations happened to be born.
How it became law
- December 2023: the Ontario Superior Court of Justice found the first-generation limit unconstitutional for many people.
- 2024–2025: the federal government chose not to appeal and instead moved to legislate a fix, introducing Bill C-3 in June 2025.
- November 2025: the bill received Royal Assent.
- December 15, 2025: the law came into force—the date that now divides the old rules from the new.
What the law does
Bill C-3 created what is effectively a two-track system, split at December 15, 2025:
- For people born abroad before December 15, 2025: the first-generation limit is removed and citizenship is recognized, retroactively, for the second and later generations born abroad, as long as the chain traces to a Canadian-citizen ancestor. There is no residency test for this group—they are recognized as citizens and apply for a certificate to confirm it.
- For people born abroad on or after December 15, 2025: a new substantial-connection test applies. A Canadian parent who was born abroad must have at least 1,095 days (three years) of physical presence in Canada before the child’s birth for citizenship to pass.
In short, the law looks backward with generosity and forward with a condition—restoring those the old cap excluded, while asking future first-generation-abroad parents to show a real tie to Canada.

How many people are affected?
Estimates vary widely, and it is worth being careful here. Commentators note that millions of Americans have some Canadian ancestry and may now have reason to check their eligibility—but the number who will actually qualify and apply is far smaller. Canada’s Parliamentary Budget Officer estimated on the order of 115,000 people affected, and the immigration minister said the government did not expect a surge. In the first months after the law took effect, IRCC issued roughly 4,000 citizenship certificates under the new rules, about half to people born in the United States. Treat “millions eligible” as a statement about the pool, not a prediction about approvals.
The June 2026 turbulence
In mid-June 2026 the program hit a very public bump. On June 13, IRCC emailed a number of people who had recently received certificates, asking them to surrender the documents pending a review—citing files that relied on genealogy-website records rather than documents from original source authorities. Within days, the department began issuing revalidation letters confirming many of those same certificates would not be cancelled, and the episode was widely reported as a reversal by late June.
Two things are essential to understand. First, Bill C-3 itself did not change—the eligibility rules stayed exactly the same; the dispute was about the standard of documentation. Second, the lasting lesson is about proof: IRCC signalled that it expects citizenship claims to rest on records traceable to official source authorities, with a documented explanation wherever an original record is unavailable. For applicants, that raises the bar on the documents you gather rather than on who is eligible.
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.
What it means for you
If you are exploring a claim, Bill C-3 is good news tempered by a practical demand: the door is open far wider than before, but you must walk through it with a well-built, well-sourced file.

Frequently asked questions
Is Bill C-3 still in force after the June 2026 review?
Yes. The review concerned the documentary standard for individual files, not the law. Bill C-3 remains in force and the eligibility rules are unchanged—but always confirm current status on canada.ca.
Does Bill C-3 mean I automatically get a passport?
No. If you qualify, you are recognized as a citizen, but you must apply for a proof-of-citizenship certificate first; a passport follows from that certificate.
The substantial-connection test in practice
The going-forward test deserves a plain explanation, because it is the part of Bill C-3 most likely to be misunderstood. It applies only to children born abroad on or after December 15, 2025, and only where the Canadian parent was themselves born abroad. For that parent to pass citizenship on, they must have accumulated at least 1,095 days—three years—of physical presence in Canada at any point before the child’s birth. The days need not be consecutive, and they can come from any period of the parent’s life in Canada. Crucially, this test does not apply to anyone born before the cutoff, which is the group most people researching their roots fall into.
What did not change
It is just as important to know what Bill C-3 left alone. It did not alter citizenship for people born in Canada, who remain citizens by birth. It did not affect anyone who was already a citizen before the law took effect. And, as the June 2026 episode confirmed, it did not change who is eligible by descent—only the scrutiny applied to the documents proving a claim. Understanding the boundaries of the reform keeps expectations realistic and your research focused on the part that matters: the documented chain.
