In family information form, it asks for sibling details.My brother is PPermanent resident in Canda,Do I need to fill his details also.?
Because in the form it says, "You (the principal applicant) must fill out this form for yourself and on behalf of any of your family members 18 years of age or older who are not already Canadian citizens or permanent residents."
Please specify which form. If you mean imm5406, that is 'additional family information' form.
Yes, you do need to include your brother under siblings of principal applicant. In the brothers and sisters section. (This would seem self-evident)
Your brother does not need to fill out a form for submission himself.
In the version of the form I have (not the online form), it has different instructions - it says principal applicant, spouse or common law partner*, and all dependent children 18 or older must fill out the form (i.e. each of those should submit a form). Your brother should not be any of those (with caveat that I am only assuming that you are principal applicant or sponsor).
If you're referring to the IMM0008, then no: your brother is not an applicant or dependent of applicant. (IRCC is a bit unclear here but the reason is he is not 'family member' but additional family or extended family; most of the time when IRCC refers to 'family member' they mean applicant + spouse + dependent children). On IMM0008, sponsor-spouse is not included because by definition sponsor is citizen or PR.
*The form is actually unclear on one point, the 'spouse or common law partner' of applicant does not need to complete this form IF that person is the sponsor.
