Short answer
A Custodianship Declaration (IMM 5646) shows that a minor student will have appropriate adult care and support in Canada. Students under 17 who are not accompanied by a parent or legal guardian must name a custodian in Canada and submit IMM 5646 with the study-permit application.

Page 1 is signed and notarized by the Canadian custodian in Canada; page 2 is signed and notarized by the parents or legal guardian in the student’s home country. The custodian must be a Canadian citizen or permanent resident living in Canada and able to provide real care and support. For students aged 17 to the age of majority, custodianship is usually discretionary, but an officer may request it based on the circumstances.
What to verify
A study permit, TRV/eTA, PAL/TAL and CAQ (where applicable) are separate requirements; check the student’s age, status and custodianship arrangement.
Planning advice
Use official school and IRCC information, maintain one consistent timeline across all documents and keep written confirmation of important conditions.
