Why claim Canadian citizenship through descent
Inherit Canadian status
Citizenship by descent confirms a status you may already hold by birthright. Bill C-3 removed the first-generation limit for those born before 15 December 2025 — eligibility follows the documented chain, not a fixed generation count.
Pass it to your children
Whether Canadian citizenship passes to a child born outside Canada depends on the Canadian parent's own situation. Under Bill C-3, a Canadian parent who was themselves born or adopted outside Canada must have at least 1,095 days of cumulative physical presence in Canada (before the child's birth or adoption) for the child to be a citizen. These outcomes are fact-specific and are confirmed by a case assessment.
Visa-free travel worldwide
The Canadian passport ranks among the strongest in the world — visa-free or visa-on-arrival access to most of the world, including the EU and the UK.
Healthcare, work, study
Citizenship grants full access to Canadian universal healthcare, work without a permit, and provincial tuition rates for Canadian universities.
Keep your current passport
Canada permits dual and multiple citizenship. You don't have to renounce U.S. or any other nationality to claim Canadian status.
Decades-old rules, newly opened
The structural rules trace back to the 1947 Citizenship Act, with retroactive 'Lost Canadians' fixes layered on since. Bill C-3 widened the door — many who assumed they were excluded now qualify. A case assessment confirms where your line stands.
Three paths to citizenship by descent
Bill C-3 restored citizenship rights to many descendants of Canadians who were previously excluded by the first-generation limit. Eligibility depends on your specific ancestral circumstances — the generational paths below are a general guide, and individual cases should be assessed by an RCIC or immigration lawyer.
- 1
Path 1 — Canadian parent
Your parent was a Canadian citizen at the time of your birth. The fastest path: typically a Proof of Citizenship application with the parent's citizenship documentation and your birth record.
- 2
Path 2 — Canadian grandparent
Your grandparent was a Canadian citizen, and the parental link to you is documentable. Bill C-3 removed the first-generation limit that previously blocked this path for many descendants.
- 3
Path 3 — Canadian great-grandparent
Your great-grandparent was Canadian and you can document an unbroken chain to the present. Note: whether a great-grandparent connection qualifies depends on the specific provisions of the Citizenship Act that apply to your ancestor's situation. Not all great-grandparent connections automatically qualify — a case assessment is strongly recommended before applying. Substantial documentary work is typically required, especially for older Quebec records.
- 4
The 1947 Citizenship Act anchor
The modern Citizenship Act came into force on 1 January 1947. A Canadian-born or naturalised ancestor living on that date is generally treated as a citizen from then. Ancestors born before 1947 — including 1800s lines — can still anchor a claim through the retroactive 'Lost Canadians' provisions, but eligibility turns on the specific Citizenship Act provisions applying to each generation (pre-1947 foreign naturalisation and the pre-1947 second-generation-born-abroad gap can break a chain). These cases require an RCIC or immigration-lawyer assessment.
- 5
Documentary chain must be unbroken
Each generation between the qualifying ancestor and the applicant must be evidenced by birth, marriage, naturalisation, or citizenship records. Gaps (e.g. missing Quebec parish records) can be reconstructed but require specialised genealogy work.
- 6
Confirmation, not a grant
Citizenship by descent confirms a status you may already hold by birthright — filed on IRCC form CIT 0001 (Proof of Citizenship), not a naturalisation grant. The criminal-prohibition rules that apply to naturalisation applicants do not generally bar confirmation of citizenship a person already holds. (Narrow fraud / misrepresentation and national-security provisions are separate and assessed individually.)
- 7
Future-children rule (1,095 days)
Applies to any Canadian citizen born abroad who wants to pass citizenship to a child born abroad after 15 December 2025. If the Canadian parent has fewer than 1,095 cumulative days of physical presence in Canada before the child's birth, the child does not automatically inherit citizenship.

Frequently asked questions
If your question isn't here, the long-form Bill C-3 guide and Lost Canadians guide cover citizenship by descent in full detail.
What did Bill C-3 actually change?
Bill C-3 (in force 15 December 2025) removed Canada's first-generation limit on citizenship by descent. Before the reform, you generally could not inherit citizenship from a Canadian grandparent or great-grandparent if you were the second generation born abroad. Bill C-3 opens that door. The 1947 Citizenship Act is the legal anchor, and pre-1947 ancestral lines can still qualify through the retroactive 'Lost Canadians' provisions — outcomes depend on the specific provisions applying to each generation.
Do I qualify if my grandparent was Canadian?
Likely yes, under Bill C-3 — provided your grandparent's Canadian status is established under the Citizenship Act (including the retroactive 1947 deeming and 'Lost Canadians' provisions for pre-1947 lines) and you can document the link from grandparent to parent to you. Mercan's free initial consultation confirms whether the path applies in your case.
What about a great-grandparent?
Under Bill C-3, yes — but you must document an unbroken chain through every generation, with official records (not just genealogy-website results). Great-grandparent cases are the most documentation-heavy. Mercan's network includes genealogists who specialise in Quebec parish records and pre-1947 naturalisation files.
How much does it actually cost?
There are two cost components. First, the IRCC proof-of-citizenship fee (currently CAD $75 per applicant; form CIT 0001), set by Immigration, Refugees and Citizenship Canada and paid directly to the government — non-refundable once processing begins. Second, professional and records costs — straightforward parent-link applications can be under C$500 all-in, while great-grandparent cases involving Quebec parish records and specialised genealogist work can run several thousand dollars. Mercan provides a personalised cost estimate after the free initial consultation.
Will I have to give up my U.S. (or other) citizenship?
No. Canada permits dual and multiple citizenship. You can hold Canadian and U.S. citizenship simultaneously. Note that the U.S. position on dual citizenship is also permissive in practice, but consult a tax adviser about U.S. tax-on-worldwide-income obligations.
Can my children become Canadian once my citizenship is confirmed?
Whether Canadian citizenship passes to a child born outside Canada depends on the Canadian parent's own situation. Under Bill C-3, a Canadian parent who was themselves born or adopted outside Canada must have at least 1,095 days of cumulative physical presence in Canada (before the child's birth or adoption) for the child to be a citizen. These outcomes are fact-specific and are confirmed by a case assessment.
Why are Quebec records harder?
Quebec birth, marriage, and death records were not standardised by the province until the 1990s. Older records sit in parish baptismal registers, often hand-written in archaic French script, and many surnames were anglicised on entry to the U.S. Mercan's genealogy network specialises in reconstructing these chains to IRCC standards.
Do I need a lawyer or can I apply on my own?
Straightforward parent-path applications can be filed independently — IRCC's CIT 0001 form is publicly available. For grandparent or great-grandparent cases, complex Quebec ancestry, or anglicised surnames, having an RCIC and a Canadian lawyer materially improves the success rate. The IRCC fee is non-refundable.
How long does the application take?
IRCC processing time varies case-by-case. With Bill C-3 in force only since December 2025, the post-reform backlog is substantial — the volume of applications has surged sharply since the reform. Plan for 4 to 12+ months depending on case complexity and current IRCC workload.
What is a "Lost Canadian"?
"Lost Canadians" are descendants — most often Americans of French-Canadian heritage in New England — whose ancestors emigrated from Canada but who were excluded from citizenship by older laws (notably the first-generation limit struck down in the Bjorkquist case). Bill C-3 was specifically drafted to give Lost Canadians a path back to citizenship.

Important considerationsSpeculative investment. Read before subscribing.
This page is informational only and does not constitute legal advice. Canadian citizenship by descent eligibility is fact-specific — the 1 January 1947 cutoff, intervening loss-of-citizenship events, criminal inadmissibility, and documentary gaps can all affect outcomes. The IRCC application fee is non-refundable regardless of approval status. Processing times stated reflect post-Bill-C-3 conditions and are subject to IRCC workload changes. Mercan strongly recommends a free initial consultation with an RCIC before submitting any application. Consult a licensed Canadian immigration lawyer for advice on your specific circumstances.
