Millions of U.S. Citizens who can trace an unbroken line of descent to a Canadian ancestor became newly eligible for Canadian citizenship by descent when Canada changed its Citizenship Act effective December 15, 2025. Most eligible people must now apply to Immigration, Refugees and Citizenship Canada (IRCC) for a proof of Canadian citizenship certificate to receive an official document and, if they choose, a Canadian passport. Demand from the United States surged after the change, with IRCC receiving thousands of proof-of-citizenship applications in the weeks after the law took effect, and processing estimates vary; some reports suggest waits of several months. The immediate practical step named by authorities is to file a complete proof-of-citizenship application with IRCC.

## 1. Confirm eligibility by descent

Start with a basic test. Under the revised rules that took effect on December 15, 2025, Canada removed the previous one-generation limit on citizenship by descent. That means anyone born before December 15, 2025 who can demonstrate a continuous line of descent from a Canadian ancestor may be considered a Canadian citizen by descent and may apply for a proof of citizenship. IRCC is the final authority on eligibility and will decide each file on its statutory footing.

Checklist for this step:

  • Birth dates for every person in the chain, from the applicant back to the Canadian ancestor.
  • Names and places that appear on official records.
  • Clear, legible civil documents linking each generation.

Worked example. Jane, born in Massachusetts in 1985, has a grandmother who was born in Ontario in 1920. Jane lines up her birth certificate, her mother's birth certificate showing the grandmother as parent, and the grandmother's Canadian birth record. Under the current change, Jane may qualify to apply to IRCC for a proof of citizenship by descent.

## 2. Check the generation and residency rules that apply to your birth date

Not all cases are identical. Confirm which statutory rule applies to the applicant’s exact year of birth and family line. The authorities require matching dates in the chain with the statutory text and IRCC guidance to determine whether the revised one-generation limit is lifted for your case.

Note about parent residency. One separate report states that people born after December 15, 2025 must show their Canadian parent lived in Canada for at least 1,095 days.

That requirement appears in a single source and isn't repeated across other accounts, so treat it as single-sourced guidance until IRCC publishes matching detail.

Worked example. If Jane’s child were born after December 15, 2025, check whether the parent's Canadian residency is relevant. If you find a claim about a 1,095-day residency rule in a single report, verify the rule with IRCC before relying on it for documentary searches.

## 3. Gather documentary proof of descent

Right now, the most time-consuming part is assembling the paper trail. Applicants must create a continuous lineage documented with civil vital records such as birth, marriage and death certificates, plus any other official records that legally link each generation. Archives, provincial registries and genealogical services have seen sharp increases in requests from U.S. Applicants since the law changed.

The Bibliothèque et Archives nationales du Québec reported a large jump in requests, and other provincial archives and registries have been busier as people hunt for Canadian records. Expect wait times from archives to vary by province and by the age of the records.

Document checklist:

  • Applicant’s birth certificate.
  • Parent(s) birth certificate(s) showing the link to the applicant.
  • Grandparent(s) birth certificate(s) or Canadian birth registration linking to a Canadian place of birth.
  • Marriage certificates, death certificates, legal name-change records where applicable.
  • Certified translations for any records not in English or French.

Worked example. If Jane can't find her grandmother’s Ontario birth registration online, she may contact the provincial archive that holds older civil registrations. Expect bilingual services in Quebec and possible fees or processing delays from the archives.

## 4. Complete and submit the proof of Canadian citizenship application

When your documents are collected, complete the IRCC proof-of-citizenship application form. Many U.S. Applicants must file on paper rather than online, so plan for mailing times and certified copies. One account notes that IRCC publishes processing timetables and that this application is the route by which an existing but previously undocumented citizenship status is formally recognized.

Mastheads

Submission checklist:

  • Completed IRCC proof-of-citizenship application form.
  • Certified copies of all required civil documents linking each generation.
  • Any required translations and proof of identity for the applicant.
  • Payment of applicable IRCC fees.

Worked example. Jane assembles certified copies of her documents, completes the IRCC form, and mails the paper application with required fees and return postage. She keeps a photocopy of the full package and notes the postal tracking number.

IRCC allows applicants to request urgent processing where the applicant faces "potential harm or hardship." The published policy explicitly includes grounds related to sexual orientation, gender identity or expression, and medical need such as access to Canadian health care. To request urgency, attach a clear explanation letter and supporting documents to the complete application package. The officer reviewing the file may decide to expedite the file at their discretion.

Some community members report very fast handling in particular circumstances. One account describes transgender applicants who said their certificates were processed in as little as two weeks under IRCC’s urgent-processing criteria. That two-week anecdote appears only in a single source and should be treated as such unless IRCC makes supporting processing data public.

Worked example. If Jane needs a certificate to access a Canadian provincial health plan for an imminent surgery, she should include a doctor’s letter and any other evidence of medical necessity when requesting urgent processing from IRCC.

Volumes rose quickly after the change. IRCC received more than 12,000 proof-of-citizenship applications in the six-week period after the law took effect, and U.S. Applicants made up the largest national share in January filings. Processing inventories and timelines increased from about five months in mid-2025 to roughly 10 to 12 months in later reports, though estimates vary by source and by application mix.

Reports describe further spikes in February and March 2026 that added thousands of files to the queue in a single month. Legal practices, archives and genealogical services report daily surges of new clients seeking help, which can add to local delays for records retrieval.

Worked example. If Jane files today, prepare for an application processing horizon measured in many months. Keep copies of sent materials and be prepared to respond if IRCC requests additional documents, which can lengthen the timeline.

Once IRCC issues an official proof-of-citizenship certificate, the applicant is entitled to apply for a Canadian passport. Passport applications use their own forms and fees. Passport applicants choose a gender marker from F, M or X. If the passport gender differs from the citizenship certificate or from a prior passport, applicants must submit a gender-identifier request form with supporting documents.

Benefits of recognized citizenship. Across the reporting, confirmed Canadian citizenship is explained to carry rights to enter, live and work in Canada, to buy residential real estate, and to access provincially administered publicly funded health-care plans if the person establishes residence. IRCC and the provinces administer different elements of those entitlements; IRCC issues the certificate and provinces determine health-care residency rules.

Worked example. After receiving her proof of citizenship, Jane completes the passport application, selects a gender marker as required, and provides the citizenship certificate as part of the passport package. If she later relocates to Ontario, she will follow that province’s rules to enroll in the provincial health plan.

Costs vary. One source reports a typical IRCC application fee of about CAD 75 where applicants already have the required documents, and warns that costs rise if applicants need professional help or overseas records searches. That CAD 75 figure appears in a single report and isn't repeated across all accounts. Other reported experiences show some applicants spending large sums on legal assistance and record retrieval, with one person reporting about USD 6,500 in expenses for professional help.

Many applicants self-file successfully by following IRCC guidance and using public archives. At the same time, immigration lawyers and consultants report sharply increased client volumes and some firms have reallocated staff to meet demand.

Cost checklist:

  • IRCC application fee (reported around CAD 75 in one account).
  • Fees for certified copies and translations.
  • Charges from archives or registries to obtain historical records.
  • Optional legal or consultant fees if you hire professional help.

Worked example. Jane calculates her costs: CAD 75 for the IRCC fee as reported in one account, plus CAD 100 for certified copies and translations, and a potential archive search fee depending on how much help she needs. If she chooses a lawyer, she budgets more depending on the complexity of her file.

Contradictions and things to verify. Sources agree the law change took effect on December 15, 2025 and that U.S. Demand surged. However, reported processing times and waiting lists differ across accounts. One report cites a roughly 10-month processing estimate and another places inventories at 56,000 waiting certificates; the 56,000 figure is single-sourced and should be verified directly with IRCC. For any point that appears in only one account, verify against IRCC guidance or the statutory text.

Final practical reminders:

  • IRCC is the decision authority for eligibility, urgent-processing requests and timing.
  • File a complete proof-of-citizenship application, including the correct form and certified lineage documents.
  • If you seek urgent processing, attach a written explanation and supporting evidence of the claimed potential harm or hardship.
