Can Siblings Apply for Canadian Citizenship Together?

The CIT 0001 form covers one applicant. Three siblings who all trace back to the same Canadian grandparent each need a separate form, a separate $75 CAD fee, and their own complete document package. But they can mail everything together in one shipment. Here is how that works, and the one risk that catches families by surprise.

No. CIT 0001 is a single-applicant form. Every person applying for a Canadian citizenship certificate completes their own form, pays their own fee, and assembles their own package. There is no family or group version.

This applies to siblings, parents, adult children, and any other relatives who qualify through the same ancestor. Each qualifying person is a separate applicant who files independently.

Yes. The fee is $75 CAD per applicant. However, IRCC allows one combined online payment for multiple applicants. If three siblings are applying, pay $225 CAD in one transaction and print one receipt with a barcode. Each applicant then includes a printed copy of that shared receipt with their individual application.

After completing separate forms and paying one combined fee, families can mail all applications together in a single package. IRCC processes each application as its own file, but accepts them arriving in one shipment.

This is common for: - Siblings applying through the same grandparent at the same time - A parent and adult child who both qualify and want coordinated timing - Cousins who share a Canadian great-grandparent

Bundling saves on shipping and aligns your timelines. If all applications are approved, everyone receives their certificate in roughly the same processing window.

One critical caveat: if IRCC finds any single application in the package incomplete, they return the entire package. Not just the problem application. All of them.

A sibling who forgot to include their photos, or whose birth certificate is missing a certified stamp, causes the other two perfectly prepared applications to come back too. All applicants restart from zero.

This is IRCC policy. It is documented in the official processing guide and is a well-known pitfall for families who bundle without checking each other's work beforehand.

The approach recommended by immigration lawyers: place each application in its own sealed inner envelope, then put all inner envelopes inside one outer shipping box (FedEx, UPS, or tracked courier).

Label each inner envelope with the applicant's full name. Include a cover letter inside the outer package that: - Names every applicant and their relationship to each other - Identifies the shared Canadian ancestor - Notes that each inner envelope is a complete, standalone application

The cover letter helps the IRCC officer immediately understand the bundle. IRCC may still return the whole package if there is a problem, but clearly labeled inner envelopes reduce confusion. Include a printed copy of the payment receipt inside each inner envelope so that each application is fully self-contained regardless of what happens.

Even when bundling, each applicant needs their own complete document package. There are no shared copies:

• Your birth certificate: your own certified government-issued copy
• Your parent's birth certificate: a certified copy per applicant, even when siblings share the same parent
• The Canadian ancestor's birth certificate: a certified copy per applicant, not one shared across the bundle
• Marriage certificates for name changes in the chain: one per applicant
• Two photos: per applicant, dated and signed by the photographer on the back
• Fee receipt: a printed copy of the shared IRCC payment attached to each file
• CIT 0001: completed and signed by each individual
• [CIT 0014 checklist](/blog/cit-0014-document-checklist): completed per applicant

If any application is separated from the bundle at any point, it must hold up as a complete standalone file. Sharing one certified copy of a grandparent's birth certificate across three applications does not meet that standard.

The cost of ordering extra certified copies ranges from $20 to $50 depending on the province and document. That is trivial compared to losing months of processing time from a returned package.

Mark and Linda both qualify for Canadian citizenship through their grandfather, born in New Brunswick in 1921. Here is their process:

1. Each completes their own CIT 0001 and CIT 0014
2. Each orders a separate certified copy of their grandfather's birth certificate from New Brunswick Vital Statistics
3. Mark pays $150 CAD online in one transaction; each prints the receipt
4. Each assembles their documents in a sealed inner envelope labeled with their name
5. Mark writes a cover letter identifying both applicants and their shared grandfather
6. Both inner envelopes go into one FedEx box, shipped to IRCC's Sydney, Nova Scotia mailing address

Processing begins for both files simultaneously. If both applications are complete, there is no downside to bundling.

Separate submissions make sense when: - One sibling's documents are still in progress and they are months behind - One application involves a complication likely to trigger an IRCC letter: a name discrepancy, late birth registration, or missing ancestor record - One applicant is uncertain about any part of their file

Separate shipments cost more individually but protect the other applicants from delays they did not cause.

If you are confident all applications are complete and correct, the bundle is efficient. If there is any uncertainty about one file, send it alone and let the others proceed.
