Bill C-3 & Canadian Citizenship,
The 2026 Guide.

Canadian citizenship by descent is the right to claim Canadian status through a qualifying ancestor — typically a parent, but, since Bill C-3 came into force on 15 December 2025, also a grandparent or great-grandparent. Unlike naturalisation (which requires permanent-resident status, three years of physical presence, language tests, and a knowledge exam), descent-based citizenship is structural: if your ancestral chain qualifies, you are a Canadian citizen — the Proof of Citizenship application simply documents what is already legally true.

The reform matters because, before December 2025, Canada operated under a first-generation limit: only the first generation born outside Canada could inherit citizenship from a Canadian parent. The second generation born abroad — children of Canadians who themselves were born abroad — were typically excluded, even when the original Canadian ancestor's citizenship was incontestable. That cut out an entire population of descendants, particularly in the United States, where over a million French-Canadians migrated south in the 19th and 20th centuries.

The headline change. Bill C-3 removed the first-generation limit. Descendants of Canadians can now inherit citizenship through three generations of ancestry, provided the qualifying ancestor became Canadian on or after 1 January 1947.

This guide walks through what changed, who qualifies under the new rules, what documents are required, what the application costs in real-world terms, and what to do if you have or plan to have children born outside Canada.

Bill C-3 is the 2025 amendment to the Citizenship Act that removed Canada's first-generation limit on citizenship by descent. The bill received Royal Assent in autumn 2025 and came into force on 15 December 2025. From that date forward, descendants of Canadians can claim citizenship through a parent, grandparent, or great-grandparent — provided the qualifying ancestor became a Canadian citizen on or after 1 January 1947.

What changed

• Before Bill C-3: only the first generation born outside Canada could inherit citizenship by descent. The second generation born abroad was generally excluded.
• After Bill C-3: the first-generation limit is gone. Descent-based citizenship can run through multiple generations, with no statutory cap on ancestral distance — the practical limit is your ability to document the chain.

Why this happened

The previous regime was struck down in Bjorkquist v. Canada (Attorney General), a 2023 Ontario Superior Court ruling that found the first-generation limit unconstitutional under the Canadian Charter of Rights and Freedoms. The court held that the limit violated equality rights by drawing arbitrary distinctions between Canadians born in Canada and those born abroad, and gave the federal government a deadline to amend the law. Bill C-3 is the federal response.

What didn't change

• The 1 January 1947 cutoff. The modern Citizenship Act took effect on this date. Ancestors who became Canadian on or after 1 January 1947 qualify; pre-1947 cases are governed by older laws and generally do not qualify under the descent rules.
• The 1,095-day rule for future children born abroad. If you are granted citizenship under Bill C-3 and intend to pass it to children born outside Canada after your grant, you must show at least 1,095 cumulative days of physical presence in Canada (counted across your lifetime up to the child's birth).
• Documentary standards. IRCC continues to require official source records — birth, marriage, naturalisation, and citizenship documents. Online genealogy sites are not sufficient as sole proof.

The reform did not come from Parliament alone. It came from the courts. In Bjorkquist v. Canada (Attorney General), the Ontario Superior Court of Justice held that Section 3(3)(a) of the Citizenship Act — the provision creating the first-generation limit — was inconsistent with the Canadian Charter of Rights and Freedoms.

The court reasoned that the limit drew an arbitrary distinction between Canadians born in Canada (who could pass citizenship to descendants regardless of ancestral distance) and Canadians born abroad (who could not pass it past one generation). That distinction, the court found, did not survive Charter scrutiny, particularly because it left certain children stateless or with inferior legal standing despite an unbroken Canadian heritage.

The federal government chose not to appeal and instead drafted Bill C-3 to comply with the ruling. The bill was tabled, debated, and passed during 2025, with the in-force date set for 15 December 2025 to give IRCC time to update its application infrastructure and processing guidelines.

For applicants, the practical takeaway is that Bill C-3 is now law, not a proposal — IRCC began accepting applications under the new rules on 15 December 2025, and the documentary standards and forms (CIT 0001 — Proof of Citizenship) are publicly available on canada.ca.

Under Bill C-3, eligibility for citizenship by descent runs through one of three relationships. The path that applies to you determines the documentary chain you'll need to assemble.

Path 1 — Through a Canadian parent

The fastest and most common path. If one or both of your parents was a Canadian citizen at the time of your birth (and the parent's citizenship was acquired on or after 1 January 1947), you are typically a Canadian citizen by descent. Application is normally via Proof of Citizenship form CIT 0001, supported by your birth certificate and your parent's Canadian citizenship documentation.

Path 2 — Through a Canadian grandparent

The path opened most broadly by Bill C-3. Before December 2025, this was generally blocked by the first-generation limit. Now, if your grandparent was a Canadian citizen (acquired on or after 1 January 1947) and the parent-to-you link is documentable through birth and (where applicable) marriage records, you may claim citizenship.

Path 3 — Through a Canadian great-grandparent

The newest path. Documentary requirements are heavier — you must show an unbroken chain of generation-to-generation links, each evidenced by official records. For families with French-Canadian ancestry in New England, the Maritime provinces, or other diaspora regions, this path is typically the most documentation-intensive because pre-1947 Quebec records require specialised genealogy work.

What all three paths share

• The 1947 cutoff: the qualifying ancestor must have become Canadian on or after 1 January 1947.
• An unbroken chain: every generation between the ancestor and you must be evidenced by official records.
• Government application fee: payable to IRCC per applicant, regardless of path.
• Inadmissibility rules: serious criminal records can bar an application even where ancestry is clear.

The 1 January 1947 date is the most-misunderstood rule in Canadian citizenship by descent. Bill C-3 did not change this cutoff — it changed the generation count, not the start date.

Why this date? Before 1947, there was no separate Canadian citizenship — Canadians were British subjects under the British Nationality Act. The Canadian Citizenship Act, 1946 (in force 1 January 1947) created Canadian citizenship as a distinct legal status. Under current rules, the qualifying ancestor must have become a Canadian citizen on or after that date.

What this means in practice

• Ancestor born after 1 January 1947 in Canada: automatically qualifies as a Canadian citizen.
• Ancestor born before 1947 but resident in Canada in 1947: typically became a Canadian citizen on 1 January 1947 by operation of law — qualifies.
• Ancestor emigrated from Canada before 1947 and never naturalised in Canada under the 1947 Act: may not qualify, depending on the circumstances of departure and any subsequent ties.
• Ancestor naturalised in another country before 1947, lost British-subject status, and never became Canadian under the 1947 Act: generally does not qualify.

Quebec records are particularly important here because Quebec emigration to New England peaked between 1840 and 1930 — many ancestors left the province before 1947 and never returned. In some cases, mid-century Canadian relatives (a Canadian grandparent or parent rather than the original migrant great-great-grandparent) provide the qualifying link.

Practical advice. Don't assume your case is hopeless because your earliest documented Canadian ancestor predates 1947. The 1947 rule applies to the qualifying ancestor in the chain — often a more recent generation. Mercan's RCIC team surfaces this automatically.

IRCC's Proof of Citizenship application (form CIT 0001) is documentation-heavy. The exact list depends on which path applies, but every application needs to evidence each link in the ancestral chain with official source records. Online genealogy services are not sufficient as sole proof.

For the qualifying ancestor

• Canadian birth certificate, OR
• Canadian Certificate of Citizenship, OR
• Canadian naturalisation record (for ancestors who naturalised under the 1947 Act).

For each generation between the ancestor and the applicant

• Long-form birth certificate showing both parents' names.
• Marriage certificate (where applicable, especially for changes of surname).
• Death certificates (for deceased intermediates, to support the documentary record).

For the applicant

• Long-form birth certificate showing both parents' names.
• Government-issued photo ID (passport preferred).
• Two passport-style photos meeting IRCC specifications.
• Proof of name changes if applicable.

The Quebec records caveat

Quebec birth, marriage, and death records were not standardised by the province until the early 1990s. Older records sit in parish baptismal registers (registres paroissiaux), often hand-written in archaic French script. Many surnames were anglicised on entry to the U.S. — "Tremblay" became "Trembly," "Bouchard" became "Bushaw," "Côté" became "Cody." Reconstructing a chain through Quebec records typically requires a specialist genealogist who can read 18th–19th century French script and resolve surname variations against parish indices.

Translations and certifications

Documents not in English or French must be officially translated and accompanied by a certified copy of the original. IRCC also accepts certified true copies of documents that cannot be released in original form (e.g. parish registers).

The mechanics of a Bill C-3 application are straightforward. The hard work is upstream — confirming eligibility and assembling the documentary chain.

1. Eligibility confirmation. Confirm which path applies to you and that the qualifying ancestor meets the 1947 cutoff. Mercan's RCIC team does this in two minutes; you can also work through it manually using the IRCC eligibility guide on canada.ca.
2. Document gathering. Order birth, marriage, death, and citizenship records for every generation in the chain. For Quebec records, engage a specialist genealogist if needed.
3. Form CIT 0001. Complete the Proof of Citizenship application form. Sign sworn declarations as required.
4. Application package. Assemble the form, the documentary chain, photos, photo ID, and the government application fee per applicant.
5. Submission. File with IRCC by mail or, where available, the IRCC online portal.
6. IRCC review. Each application is reviewed case-by-case. IRCC may request additional evidence — Mercan tracks the file and responds to RFEs (requests for evidence) on your behalf.
7. Certificate of Citizenship issuance. On approval, IRCC issues your Canadian Certificate of Citizenship. This is the document you use to apply for a Canadian passport, Social Insurance Number (SIN), and provincial healthcare.

What if I'm denied?

If IRCC denies the application, you have the right to a written explanation and, in many cases, the right to apply for judicial review at the Federal Court. Denials are most often documentary (a missing or contested record in the chain) rather than substantive — meaning a denied application can frequently be re-filed once the documentary gap is closed.

The IRCC application fee is the same for every case — payable per applicant when you file Form CIT 0001 (Proof of Citizenship). Real-world total cost varies widely depending on case complexity.

What you'll always pay

• The IRCC application fee — payable to the Government of Canada, per applicant.
• Birth, marriage, and death certificate fees — vary per document and jurisdiction. A grandparent-path application might involve 4–6 documents; a great-grandparent path can require 10 or more.
• Translation and certification — required for documents not in English or French.

What may add to the bill

• Genealogist fees — for Quebec records or anglicised-surname reconstruction. Engagements are typically flat-fee, sized to case complexity.
• Legal / RCIC fees — for case strategy, application preparation, and IRCC liaison. Mercan operates on transparent flat-fee or capped engagements.
• Additional records research — parish-register access, naturalisation-file retrieval, archive requests. Variable.

Realistic complexity tiers

• Simple parent-path application: a small documentary chain — fees, records, translations.
• Grandparent path with clean records: moderate documentary work and translation.
• Great-grandparent path with Quebec records: substantial genealogy work, with most of the cost going to the specialist research rather than the application itself.

Cost honesty. The government fee is a small fraction of total spend for complex cases. Anyone quoting a single low number for a grandparent-or-deeper claim is underestimating the records work. Mercan provides a personalised estimate after the free initial consultation.

Bill C-3 created a substantial spike in applications. The most-recent published IRCC numbers (covering 15 December 2025 through 31 January 2026 — the first six and a half weeks of the new regime) tell the story:

• 12,430 applications received
• 6,280 applications processed
• 1,480 applications granted

That ratio reflects the fact that many post-Bill-C-3 applications involve grandparent or great-grandparent paths with substantial documentary requirements — IRCC review takes longer when the chain is more complex.

What to expect

• Parent-path applications: commonly cleared in 4 to 8 weeks.
• Grandparent-path applications: typically 4 to 8 months, depending on documentary completeness.
• Great-grandparent-path applications: 8 to 12+ months in many cases, with substantial RFE (request for evidence) traffic during review.

How to be in the faster cohort

1. File a complete chain on day one. Most delays are documentary — a missing or contested record triggers an RFE that adds 6–12 weeks. Pay the genealogy work upstream, not downstream.
2. Use translated, certified copies. IRCC will not chase missing translations.
3. Use the Mercan or other RCIC channel for RFE response. An RFE is not a denial, but a slow response will be treated as one.

The post-Bill-C-3 backlog is real and not going away soon — Canadian genealogist Ryan Légère, quoted in Yahoo News coverage, noted that "many institutions appear to be overwhelmed, understaffed, and not fully prepared." Plan for the longer end of the range.

Bill C-3 made it easier to claim citizenship by descent — but it also clarified the rules for passing it on. If you are granted citizenship under Bill C-3 and intend to have children born outside Canada in the future, the 1,095-day rule applies.

What the rule says

To pass Canadian citizenship to a child born abroad after your grant, you must show at least 1,095 cumulative days of physical presence in Canada, counted across your lifetime up to the child's birth. The 1,095 days do not need to be consecutive, and they include time spent in Canada before you were granted citizenship under Bill C-3.

What counts as physical presence

• Days you were physically inside Canada — verifiable against passport stamps, travel records, employer or educational records, and CBSA entry/exit data.
• Days you were a permanent resident or citizen residing in Canada.
• Days as a temporary resident (work or study permit holder) physically in Canada.

What doesn't count

• Days outside Canada, even on Canadian-government work or study assignments (with limited exceptions for Crown service).
• Time imputed from constructive presence (e.g. "I felt Canadian" doesn't count).

What if I haven't accumulated 1,095 days yet?

Children already born when you are granted citizenship typically inherit your status under the descent rules in force at their birth — the 1,095-day rule applies to future children. If you intend to have children abroad and have not yet accumulated 1,095 Canadian days, options include relocating to Canada with permanent-resident status (which counts toward the 1,095), planning future births in Canada, or applying for the child's citizenship through a separate provision (e.g. naturalisation later in life).

This rule is specific. It does not affect existing children, and it does not affect your own status. It governs the conditions under which children born abroad after your Bill C-3 grant inherit Canadian citizenship automatically.

A Canadian Certificate of Citizenship is the underlying document. With it, you can apply for:

• A Canadian passport. Among the world's strongest, with visa-free or visa-on-arrival access to 185+ countries including the entire European Union, the United Kingdom, and Japan.
• A Social Insurance Number (SIN). Required to work in Canada and to file Canadian taxes if you become resident.
• Provincial healthcare enrolment. Subject to provincial residency requirements (typically 3 months of physical presence to activate coverage).
• Right to work without a permit. Anywhere in Canada, in any sector.
• Right to study at domestic-tuition rates. A material savings — Canadian universities charge international students 3 to 5x the domestic rate.
• Right to vote in federal, provincial, and municipal elections (subject to ordinary residency rules for provincial and municipal franchise).
• Right to run for federal office, subject to standard candidacy rules.
• Right to pass citizenship on to your descendants — subject to the 1,095-day rule for children born abroad after your grant.

What it doesn't change automatically

• Tax residency. Citizenship is not the same as tax residency. You become a Canadian tax resident when you establish significant residential ties (home, spouse, dependents, healthcare, driver's licence) in Canada — not by holding a passport.
• Other citizenships. Canada permits dual and multiple citizenship. You do not have to renounce your other passport.
• U.S. tax exposure. If you are a U.S. citizen, the IRS taxes worldwide income regardless of where you live. Becoming Canadian does not change your U.S. tax filings.

Bill C-3 is solvable on your own for the simplest parent-path cases — IRCC's CIT 0001 form is publicly available, and the documentary chain for a recent Canadian-born parent is small. For grandparent and great-grandparent paths, the calculus changes: most denials are documentary, IRCC application fees are non-refundable, and Quebec ancestry adds a research dimension that most general-practice law firms aren't equipped to handle.

What Mercan adds

• RCIC-licensed Canadian consultants. Regulated by the College of Immigration and Citizenship Consultants, with the right to represent you directly to IRCC.
• Free initial consultation. A 30-minute call with an RCIC who reviews your ancestry, confirms which of the three paths applies, and outlines the document and genealogy work your case will need.
• Vetted Canadian immigration lawyer network. For complex cases — Charter arguments, judicial review, or RFE responses — referrals to lawyers with citizenship-by-descent specialisation.
• Quebec records and genealogy specialisation. Reading parish registers, resolving anglicised surnames, reconstructing pre-1947 chains.
• Document concierge. Ordering certificates, managing translations, assembling the application package to IRCC standards.
• Transparent fees. Flat-fee or capped engagements with a written estimate before you commit.
