01 / START WITH THE REQUIREMENTS
Does IRCC require a cover letter?
A general-purpose cover letter is not listed as a universal requirement for every Canadian citizenship-certificate application. The purpose of an optional letter is to make the documented family relationship and attached evidence easier to follow.
IRCC does require written explanations in certain situations. If you cannot provide official documents issued by the original authority, IRCC says you must explain why in writing and show evidence that you tried to obtain them.
Separate the two things
Required: the applicable application forms, checklist, evidence, photographs and mandatory explanations. Suggested: a clear, concise introductory letter and a document index where they help with an unusual family line.
Know your application route
IRCC's current online instructions say that applicants born outside Canada to a Canadian parent who was also born outside Canada must use a paper application. For other situations, check the current eligibility instructions; the cover letter does not determine the route.
Bill C-3 changed the citizenship-by-descent rules effective December 15, 2025. Certain children born abroad on or after that date to a Canadian parent also born abroad may be subject to the parent's 1,095-day physical-presence requirement and related evidence requirements. Historical cases can require additional legal analysis, especially for ancestors born before 1947.
Applicant and purpose. Identify yourself and say you are applying for a Canadian citizenship certificate.
Direct family line. List each relevant generation, including the birth record or other source supporting each relationship.
Attached evidence. Refer to documents with codes such as A1, A2 and B1; use a separate short index if helpful.
Special circumstances. Explain verified name changes, unavailable birth or baptism records, unusual parentage evidence, or material historical events.
Request for assessment. Ask IRCC to determine citizenship status under the applicable legislation rather than asserting the outcome.
Our editorial recommendation
Keep the main letter around one or two pages unless the facts justify more. IRCC does not prescribe this length or endorse a specific template. Use a separate explanation sheet for a difficult missing-record search.

Choose the closest example.
These independent examples illustrate how to organize facts. They are not IRCC-approved templates and have not been represented as approved applications. Replace every placeholder, remove irrelevant lines, and verify each claim against the records you actually have.
Fictional family / complete records
Emily Parker (fictional) was born in Michigan in 1992 to a mother born in Ontario in 1965. Records for both generations are available. The marriage certificate helps connect surnames; additional evidence might be needed depending on the actual name change.

Re: Application for a Canadian Citizenship Certificate — Proof of Citizenship
Dear IRCC Officer,
I am submitting an application for a Canadian citizenship certificate based on my descent from my mother, Claire Martin Parker, who was born in Toronto, Ontario, Canada, in 1965.
I was born in Michigan, United States, in 1992.
The enclosed records support our parent-child relationship and help establish the connection between my mother's surnames:
A1 — Ontario birth certificate for Claire Martin.
A2 — Michigan birth certificate for Emily Parker, identifying Claire as my mother.
A3 — Marriage certificate for Claire Martin, helping connect the surnames Martin and Parker.
I respectfully request that IRCC review my application and supporting evidence to determine my Canadian citizenship status.
Thank you for your consideration.
Sincerely,
Emily Parker
Anonymized research pattern / not an approved case
This pattern is adapted from our ongoing family research: Quebec 1874 → Wisconsin 1918 → Wisconsin 1955 → United States 1980. It is not a claim that IRCC has accepted the family line or issued a certificate.

Re: Application for a Canadian Citizenship Certificate — Multigenerational Descent
Dear IRCC Officer,
I am submitting an application for a Canadian citizenship certificate based on my maternal family line originating with my great-grandfather, [Ancestor’s full name], who was reportedly born in Quebec, Canada, in approximately 1874.
The direct family line reflected in my research is:
G0 — [Great-grandfather], born approximately 1874 in Quebec, Canada.
G1 — [Grandfather], born in Wisconsin in 1918; son of G0.
G2 — [Mother], born in Wisconsin in 1955; daughter of G1.
G3 — [Applicant], born in the United States in 1980; child of G2.
I have enclosed documents relevant to this family line, organized by generation and identified in the supporting-document index. These include Canadian historical material and U.S. vital records establishing the successive parent-child relationships, to the extent documented by the enclosed records.
[Include a brief statement of any verified naturalization or historical nationality events, with references to the records actually enclosed. Omit if not relevant.]
[If an original-authority record is unavailable, refer to the attached written explanation and evidence of attempts to obtain it.]
I understand that the citizenship implications of this historical family line must be assessed under the applicable legislation. I respectfully request that IRCC review the enclosed evidence and determine my Canadian citizenship status.
Thank you for your consideration.
Sincerely,
[Applicant’s full name]
Entirely fictional / historical records gap
Margaret Fraser is fictional. The 1890 Nova Scotia birth date is chosen because regular provincial birth registration was interrupted at the time; delayed registrations may still exist and must be considered.

Re: Citizenship Certificate Application — Explanation of Unavailable Historical Birth Registration
Dear IRCC Officer,
I am submitting an application for a Canadian citizenship certificate supported by a documented family line originating with [Margaret Fraser], who was reportedly born in Nova Scotia, Canada, in 1890.
A conventional provincial birth registration has not been located. Nova Scotia’s regular civil registration of births was interrupted between 1877 and October 1908, which includes the reported birth year. However, delayed birth registrations can exist, so I also requested a search for any applicable delayed registration.
On [Date], I contacted [Original Record Authority] and requested a search for this ancestor's birth record. On [Date], the authority reported that no matching record was located in the holdings searched. Copies of the request and response are enclosed.
I have included the following supporting documents:
H1 — Historical baptismal record from [Original Record Authority].
H2 — Canadian census record from [Official Repository].
H3 — Written reply from the provincial records authority.
H4 — Correspondence documenting attempts to locate the birth record.
H5 — Later vital records establishing the successive parent-child relationships.
These materials are submitted as historical evidence and as an explanation of why the expected provincial birth record could not be provided. I understand that IRCC will assess whether the evidence is sufficient and may request more information.
I respectfully request that IRCC consider the enclosed explanation and records when evaluating my application.
Thank you for your consideration.
Sincerely,
[Applicant’s full name]
Do not assume an ancestor's nineteenth-century Canadian birthplace proves that all descendants automatically qualify. For ancestors born before Canada's first Citizenship Act took effect in 1947, the applicable nationality rules can be complex.
04 / WHEN THE IDEAL DOCUMENT ISN'T THERE
Document the search. Preserve the source.
IRCC requires authentic, reliable and verifiable records for each relevant generation, issued by the authority that created or now holds the record. Your application cannot be supported solely by third-party genealogy records.
If you cannot obtain a birth or baptismal record from the original authority, IRCC says to provide a written explanation and proof that you tried to obtain it. That might include dated emails, letters or a written no-record response. Be precise: “not located in the holdings searched” is not the same as “never existed.”
Potential alternatives
Depending on the case, IRCC identifies baptismal records, census records, boat manifests, certain historical nationality records and other original-authority evidence.
Source first
Keep archive names, references, correspondence and provenance together. A genealogy-site image can help you locate a record but may not substitute for original-authority documentation.
Two practical issues
Historic birth registration: Ontario provincial civil registration began in 1869. Nova Scotia had a gap in regular birth registration from 1877 until October 1908; some delayed records exist.
Historic naturalization: A U.S. declaration of intention generally was not completed naturalization. Record the actual events and dates separately; do not infer their effect on Canadian citizenship without evaluating the relevant law.
In our own research we obtained archival records and retained a church archive's written response when a Quebec baptism was not located in the collection searched. These are documented research steps, not proof that IRCC has accepted that particular evidence package.
IRCC publishes separate photograph guidance for paper and online citizenship-certificate applications. Use the citizenship-certificate specifications—not generic U.S. passport photo settings.
Paper / 2 prints
Two identical, professionally printed colour photos. The back must carry the applicant's name, the photographer or studio's full name and address, and the date photographed.
Online / 1 file
One colour JPG/JPEG photo for eligible online applicants. At least 420 × 540 pixels; no more than 4 MB, with photographer information on a receipt or separate text file.
Measurement
Official specification
Photo
50 mm wide × 70 mm high (2 × 2¾ inches)
Face height
31–36 mm from chin to the natural crown of the head
Recency
Taken no more than six months before application submission
Expression
Neutral, mouth closed and eyes open
Background
Plain white or light-coloured, with even lighting
Origin
A commercial photographer or studio; original, unaltered photograph
Important: do not digitally modify the photograph
IRCC prohibits image alterations, including changing a background and cropping or repositioning the head and shoulders as a technical edit. Do not use a DIY alignment template or AI editor to produce a Canadian citizenship-certificate photo. Give the official page to a commercial photographer instead.
Children and newborns
Only the child's head and shoulders should appear; neither the parent's nor the child's hands may be visible. For newborns, IRCC permits a photo taken in a car seat with a white blanket covering the seat and no shadows, and allows some flexibility in infant expression.
Before leaving the photographer
Confirm the finished physical size is 50 × 70 mm, not a standard 2 × 2-inch U.S. passport photo.
Verify the chin-to-crown measurement of 31–36 mm.
For paper submissions, check both prints and the identifying details written on the back.
For online submissions, ask for the original acceptable JPEG and the required photographer information.
A cover letter does not replace IRCC forms or required evidence. For a paper application, IRCC instructs applicants to place the completed CIT 0014 document checklist on top and to arrange the documents and forms in checklist order.
This interactive checklist is a personal reminder, not a replacement for IRCC's official checklist. It is not submitted to IRCC and does not store your selections.
Paper application vs. paper certificate
These are different. The method used to apply does not, by itself, decide whether your eventual citizenship certificate will be delivered on paper or electronically.
