Canadian Citizenship,
by Descent.

Key takeaways

1. 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. 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. 3

   Path 3 — Canadian great-grandparent

   Your great-grandparent was Canadian and you can document an unbroken chain to the present. The newest path opened under Bill C-3 — substantial documentary work required, especially for older Quebec records.

4. 4

   Ancestor became Canadian on or after 1 Jan 1947

   The qualifying ancestor must have acquired Canadian citizenship on or after January 1, 1947 — the date the modern Citizenship Act came into force. Earlier ancestors do not qualify under the current rules.

5. 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. 6

   No criminal inadmissibility

   Standard Canadian inadmissibility rules apply. Serious criminal records may bar an application even where ancestry is clear.

7. 7

   Future-children rule (1,095 days)

   If you are granted citizenship and intend to pass it to children born abroad after your grant, you must have spent at least 1,095 cumulative days physically in Canada — counted across your lifetime up to the child's birth.

1. 1

   Free eligibility consultation

   1 call

   Mercan's Canadian-immigration team reviews your ancestry and confirms which of the three paths applies — parent, grandparent, or great-grandparent. We then outline the document checklist and any genealogical work your case requires. No cost, no obligation.

2. 2

   Document gathering

   2–8 weeks

   Collect official birth, marriage, naturalisation, and citizenship records for every generation in the chain. Mercan's network handles Quebec parish records, anglicised-surname matching, and certified translations.

3. 3

   Genealogical chain reconstruction

   2–6 weeks

   For grandparent and great-grandparent paths, Mercan's genealogist verifies the unbroken ancestral chain and assembles supporting evidence to IRCC standards.

4. 4

   Proof of Citizenship application (CIT 0001)

   1–2 weeks

   Mercan's RCIC prepares and files form CIT 0001 with IRCC. The IRCC application fee is paid directly to the government, per applicant. Application includes the full documentary record + sworn declarations.

5. 5

   IRCC review

   Variable

   IRCC reviews each application case-by-case. Post-Bill-C-3 backlog means timelines vary substantially. Mercan tracks the file and responds to any IRCC requests for additional evidence.

6. 6

   Certificate of Citizenship delivered

   Issued by IRCC

   On approval, IRCC issues your Canadian Certificate of Citizenship. With the certificate you can apply for a Canadian passport, SIN, and provincial healthcare.

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 — provided the qualifying ancestor became Canadian on or after 1 January 1947.

Do I qualify if my grandparent was Canadian?

Likely yes, under Bill C-3 — provided your grandparent became a Canadian citizen on or after 1 January 1947 and you can document the parental link from grandparent to parent to you. Mercan's free initial consultation walks you through the chain and 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 application fee, set by Immigration, Refugees and Citizenship Canada and paid per applicant directly to the government. 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 if I'm granted citizenship?

Children already born when you are granted citizenship typically inherit your status. For children born abroad after you are granted citizenship, the 1,095-day rule applies — you must show at least 1,095 cumulative days of physical presence in Canada (across your lifetime up to the child's birth) for them to inherit Canadian status automatically.

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 — recent reporting cited 12,430 applications received in the first six weeks alone, with 1,480 granted to date. 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.
