IRCC Form IMM 5406: How to List “All Family” Without Triggering a Misrepresentation Flag
Executive Summary: The Misrepresentation Trap
The imm 5406 (Additional Family Information) form appears deceptively simple, but it is one of the leading causes of IRCC misrepresentation bans in 2026. Because IRCC cross-references this document against future family sponsorship applications and digital records, omitting a half-sibling, step-parent, or estranged child can lead to a 5-year ban from Canada. RCIC Vineet explains how to execute a flawless submission.
- Who Must Be Listed: You must list *every* member of your immediate family, regardless of whether they are accompanying you to Canada, whether they are estranged, or whether they are deceased.
- The "Half" and "Step" Rule: Section B and Section C mandate the inclusion of all half-siblings, step-siblings, step-children, and adopted children. Omissions here are treated as intentional fraud.
- The Native Script Mandate: In 2026, IRCC strictly enforces the rule that all names must be written in both English/French *and* your native linguistic script (e.g., Arabic, Mandarin, Cyrillic).
- The Consequences of Omission: Under Section 40 of the *Immigration and Refugee Protection Act* (IRPA), failing to list a family member on the imm 5406 triggers a 5-year inadmissibility ban and prevents you from ever sponsoring that person in the future (Regulation 117(9)(d)).
IRCC Form IMM 5406: How to List "All Family" Without Triggering a Misrepresentation Flag in 2026
When applying for Permanent Residence, a study permit, or a work permit, Immigration, Refugees and Citizenship Canada (IRCC) will ask you to fill out the imm 5406 form, titled "Additional Family Information." To the average applicant, this document seems like a basic background check. In reality, it is a legally binding foundational document that IRCC uses to map your entire genealogical tree.
In 2026, IRCC utilizes advanced AI cross-referencing to check family data across global visa applications. If your brother applies for a visitor visa to Canada in three years and lists you as his sibling, but you failed to list him on your imm 5406 form today, IRCC’s system will automatically flag your file for misrepresentation.
RCIC Vineet and the Liberty Immigration team review thousands of these forms. The most common mistakes involve estranged family members, step-relatives, and incorrect signature protocols. Here is the definitive 2026 guide to completing the form flawlessly, protecting your immigration status, and preserving your future family sponsorship rights.
Is Your IMM 5406 Correct? Book a Document Review Before You Submit1. Section A: The Applicant, Spouse, and Parents
Section A sets the foundation of the imm 5406 form. You must list yourself, your spouse or common-law partner, your mother, and your father. The rule here is absolute completeness.
| Family Member | 2026 IRCC Guidelines for Section A |
|---|---|
| The Applicant | This is you. You must provide your full legal name, date of birth, marital status, and your current residential address. |
| Spouse / Common-Law Partner | If you are legally married or have lived with a partner for 12 consecutive months, they must be listed here—even if you are currently separated but not yet legally divorced. |
| Mother & Father | You must list your biological or legally adoptive parents. If you do not know the identity of a parent, write "UNKNOWN" in the name field. Do not leave the row blank. |
| Deceased Relatives | If your parent or spouse has passed away, you must still list them. Write their full name, and in the address box, explicitly write "DECEASED" followed by the city and country where they passed away. |
At the top of the imm 5406, IRCC explicitly instructs you to write all names in English or French AND in your native script (if applicable). If your native language uses non-Latin characters (e.g., Chinese characters, Arabic script, Cyrillic, Hindi, Farsi), you must write the name in both alphabets in the "Name" box. Submitting only the English spelling when you are from a non-Latin script country will result in the application being returned as incomplete.
2. Section B & C: The "Step" and "Half" Bloodline Rule
Sections B (Children) and C (Brothers and Sisters) are where the vast majority of applicants make fatal errors. The imm 5406 form is not just asking for the family members you are close with; it demands your complete genealogical tree.
- Children (Section B): You must list all biological children, adopted children, and step-children. Even if your spouse has a child from a previous marriage who does not live with you, they are legally your step-child and must be declared. If your child is estranged and you do not know where they live, you must list their name and write "ESTRANGED/ADDRESS UNKNOWN" in the address field.
- Siblings (Section C): You must list all brothers and sisters. This explicitly includes half-brothers, half-sisters, step-brothers, and step-sisters. If your father remarried and had a child, that child is your half-sibling and must be listed on your imm 5406.
If you run out of space in Section B or C because you have a large family, you cannot simply omit the youngest siblings. You must print a second copy of the imm 5406 form, fill out the remaining family members, sign the new page, and attach it to your application package.
3. The Devastating Consequence of Regulation 117(9)(d)
Why is IRCC so strict about the imm 5406? The answer lies in Section 40 of the Immigration and Refugee Protection Act (IRPA), which deals with misrepresentation, and Regulation 117(9)(d).
If you fail to declare a family member—such as a child from a previous relationship—IRCC assumes you did so to avoid having that child undergo a medical or background check. If you become a Permanent Resident and later decide you want to sponsor that undeclared child to come to Canada, you will be hit with Regulation 117(9)(d).
This regulation states that a family member who was not declared and examined during your initial PR application is permanently excluded from the family class. You will never be legally allowed to sponsor them. Furthermore, the discovery of the omission will trigger a misrepresentation investigation into your own status, potentially resulting in a 5-year ban and the revocation of your PR.
Never omit a family member simply because you do not get along with them. List their full name and date of birth. If you genuinely do not know their current address or marital status, write "UNKNOWN - ESTRANGED". Honesty about missing information is acceptable; omitting the person entirely is fraud.
4. Section D: Signatures and The Unaccompanied Minor
The final section of the imm 5406 is the signature block. The rules surrounding signatures have adapted for the 2026 online portals.
- Digital vs. Wet Signatures: If you are applying through the modern IRCC PR Portal or Authorized Representative Portal, you generally type your name electronically. However, if you are uploading a static PDF for a paper-based or specific portal stream, you must print the form, physically sign it in blue or black ink, and scan it back in.
- Who Needs Their Own Form: The principal applicant must fill out their own form. Additionally, the accompanying spouse/partner and every accompanying dependent child aged 18 or older must fill out their own separate imm 5406 form, listing their specific parents and siblings.
- Declaration Sections: Notice that Section A has a signature block stating "I certify that I do not have a spouse...". Do not sign this unless you are truly single. Section B has a signature block stating "I certify that I do not have any children." Only sign there if you are childless. Everyone must sign the bottom of Section D to certify the entire form is accurate.

The principal applicant must fill it out. Additionally, any accompanying spouse/common-law partner, and any accompanying dependent child aged 18 or older, must complete their own separate IMM 5406 form.
2. Do I need to list family members who are NOT coming to Canada?
Yes. The IMM 5406 is a complete family tree declaration. You must list all parents, siblings, and children regardless of whether they are accompanying you to Canada.
3. What if my parents are deceased?
You must still list their names and dates of birth. In the address box, write 'DECEASED' followed by the city and country where they passed away.
4. Do I have to list half-siblings?
Yes. Section C explicitly requires you to list all biological siblings, half-siblings, and step-siblings.

List his full name and birth details. In the address section, write 'UNKNOWN - ESTRANGED'. Do not leave the row blank or omit him from the form.

Failing to list a child constitutes misrepresentation. Under Regulation 117(9)(d), you will be permanently banned from ever sponsoring that child to Canada in the future, and your own PR status could be revoked.
7. What does the "native script" rule mean?
If your native language uses non-Latin characters (like Arabic, Chinese, Cyrillic, or Hindi), you must type or write the family member's name in both English/French AND the native script in the name field.
8. I ran out of room for my siblings. What do I do?
You must print or generate a second copy of the IMM 5406 form, fill out the remaining sibling names in Section C, sign the bottom of the extra page, and include it in your application.
9. Do I sign Section A if I am married?
No. The signature block directly below Section A is only to be signed if you are declaring that you DO NOT have a spouse or common-law partner.
10. Do I sign Section B if I have children?
No. The signature block below Section B is a declaration that you DO NOT have any biological, adopted, or step-children. Only sign it if you are childless.
11. Where do I sign to validate the whole form?
Everyone must sign and date the final declaration block at the very bottom of the form in Section D, confirming that all provided information is true.
12. Do I list my spouse's parents on my form?
No. You only list your own biological/adoptive parents on your form. Your spouse will list their parents on their own separate IMM 5406 form.
13. Do step-children go on the form?
Yes. In Section B, you must list all biological children, legally adopted children, and step-children.
14. What if I don't know my sibling's date of birth?

15. Is a digital signature acceptable?
If you are applying through the new IRCC PR online portals, a typed electronic signature is usually acceptable. If uploading to older portals or submitting via paper, it must be printed, signed in ink, and scanned.
16. Can IRCC find out if I hide a sibling?
Yes. IRCC uses advanced cross-referencing. If your hidden sibling applies for a Canadian visa years later and lists you as their brother/sister, IRCC's system will instantly flag the discrepancy.
17. Does my 16-year-old child need their own form?
No. Only dependent children who are 18 years of age or older must complete their own independent IMM 5406 form.
18. What if my parents divorced and remarried?
In Section A, list your biological parents. In Section C, you must list any step-siblings or half-siblings that resulted from your parents' new marriages.
19. How do I format the dates?
IRCC standard date format is YYYY-MM-DD. Ensure all dates of birth are entered in this exact format to avoid system validation errors.
20. Does this form require validation online?
Unlike the IMM 0008 or IMM 5669, the IMM 5406 does not have a 'Validate' button that generates barcodes. You simply fill it out completely, sign it appropriately, and submit it.
