Immigration Canada requires that all international students under 18 appoint a custodian to act in their parents’ place. This notarized declaration must be signed by the parents and the custodian. The Abbotsford School District can act as the custodian free of charge. If you decide to choose your own custodian, they must be at least 25 years old, a Canadian citizen or a permanent resident, and reside in the Abbotsford area.
