Why claim Canadian citizenship by descent
Inherit Canadian status
Citizenship by descent confirms a status you may already hold by birthright. Bill C-3 removed the first-generation limit to citizenship by descent. Past generations can become the anchor to proving citizenship.
Pass it to your children
A child born or adopted abroad by a Canadian citizen before December 15, 2025 is automatically entitled to Canadian citizenship. If a Canadian parent gives birth to or adopts a child outside of Canada on or after December 15, 2025, they must have accumulated 1,095 days of physical presence (in their life time) in Canada in order for the child to be eligible for Canadian citizenship.
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.
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 a Registered Canadian Immigration Consultant (RCIC) or an immigration lawyer.
- 1
Path 1 — Canadian parent
Your parent was a Canadian citizen at the time of your birth or adoption (before December 15, 2025); or obtained proof of Canadian citizenship as a result of Bill C3. The fastest path: typically a Proof of Citizenship application with the parent's citizenship documentation and your birth or adoption record simplifies the process.
- 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 line of descent to the present. 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 Citizenship Act came into force on 1 January 1947. A Canadian-born or naturalised ancestor living in Canada on that date generally became automatically a Canadian citizen. Ancestors born before 1947 — including 1800s lines — who did not receive canadian citizenship on that date are considered 'Lost Canadians' and can still anchor a claim through the retroactive provisions. These cases require extensive genealogical research and documention as well as the expertise of a Registered Canadian Immigration Consultant (RCIC) or an immigration lawyer.
- 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 granting, of citizenship
Citizenship by descent confirms a status you already hold by birthright — filed on IRCC form CIT 0001 (Proof of Citizenship), not a naturalisation grant.
- 7
Future-children rule (1,095 days)
The new 1095 rule 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 in their life time 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 since December 15, 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 or third generation born abroad. Bill C-3 opens that door.
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 line of descent through every generation, with official records (not just genealogy-website results). Great-grandparent and great-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?
The total cost incurred to apply for proof of canadian citizenship has different components: 1) The fee required by Immigration, Refugees and Citizenship Canada to submit your application once completed. At this time, thee fee is set at $75 CAD per applicant 2) Gathering all the required documents, having them translated as required and getting all original certifications and apostilles involves fees that can total anywhere from $500 to a few thousands depending on the complexity of your case. 3) Fees charged by consultants and solicitors who specialise in and are accredited for Canadian immigration matters.
Will I have to give up my U.S. (or other) citizenship?
No. Both Canada and the US permits dual and multiple citizenship. 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 or adopted outside Canada depends on the Canadian parent's own situation. As a general rule: If the child was born (or adopted) outside Canada to a canadian parent before December 15, 2025, they are automatically considered canadian citizen and can apply for their certificate. If a child was born outside Canada to a canadian parent on or after December 15, 2025, the parent must have accumalated at least 1095 days of physical presence in Canada prior to the birth in order to pass citizenship eligibility to the child. Adoptions have a diffferent set of provisions and processes. This means that in most cases you’re automatically a Canadian citizen if you were born before December 15, 2025 outside Canada to a Canadian parent. This rule also applies to you if you were born to someone who became Canadian because of these rule changes (Bill C-3).
Why are Quebec records harder?
Quebec records were not standardised by the province until the 1990s. Older records sit in parish baptismal registers or hadwritten census records, often hand-written in archaic French script. Also, 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 a RCIC and a Canadian immigration lawyer materially improves the success rate. The IRCC application fee is non-refundable and, more importantly, if your file is rejected, you will have to reapply from scratch at a later date.
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 5 to 24 months depending on case complexity and current IRCC workload.
What is a "Lost Canadian"?
"Lost Canadians" are most often ancestors of French-Canadian heritage who emigrated from Canada and fell through the cracks on January 1, 1947 when the Citizenship Act came into effect. Their descendants were excluded from citizenship until Bill C-3 which was specifically drafted to give Lost Canadians and their descendants 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.
