OSAP Affidavit Notarization – What Students Need to Know in Ontario
In Ontario,
OSAP affidavits must be signed and commissioned by a qualified notary public, lawyer, paralegal, or commissioner of oaths to be considered valid. This notarization process confirms that the information in the affidavit is accurate, and that the student fully understands the declaration they’re making.

What is an OSAP Affidavit?
An OSAP affidavit is a sworn document sometimes required as part of your Ontario Student Assistance Program (OSAP) application. It’s used when you need to verify certain facts that cannot be proven through standard documents — such as estrangement from parents, sole-support status, or unique financial circumstances.
Who Requires a Custodian Declaration?
Any minor under the age of majority (18 or 19, depending on the province) entering Canada to study alone must have a custodian appointed in writing. The IMM 5646 form formally designates a responsible adult in Canada and confirms their commitment to act on behalf of the child in case of emergency.
This document must be
notarized to be valid for immigration processing.
