Custodian Declarations (IMM 5646) Notarization
Custodian Declarations are a critical requirement for minors studying in Canada without a parent or legal guardian. Schools, international recruiters, and designated custodians must ensure these forms are properly completed and notarized in accordance with
Immigration, Refugees and Citizenship Canada (IRCC) guidelines.

What Is a Custodian Declaration (IMM 5646)?
The Custodian Declaration (Form IMM 5646) is a required document for minors under 18 or 19 (depending on the province) who plan to study in Canada without a parent or legal guardian. It designates a Canadian adult as the minor’s custodian, giving them authority and responsibility while the student is in the country.
This form must be notarized to be accepted by Immigration, Refugees and Citizenship Canada (IRCC).
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.
