IMM 5646 Custodian Declaration for International Students

Agreed to be the custodian for a child coming to study in Canada? IRCC requires the custodian’s part of the IMM 5646 to be notarized in Canada. Our notaries can do it the same day.

What is the Custodian Declaration?

When a minor comes to Canada to study without a parent or legal guardian, a responsible adult in Canada must agree to act as their custodian. The IMM 5646 records that arrangement.

The form has two parts. The custodian’s page is signed by the custodian and notarized in Canada. The parents’ page is signed by the parents or legal guardians and notarized in their home country. IRCC asks for both pages with the study permit application.

Who needs it

  • Canadian citizens or permanent residents acting as custodian
  • Host families and relatives of international students
  • Parents abroad sending a child under 17 to study in Canada
  • Students 17 and older, if an officer asks for it

How it works

Fill in the custodian page

Download the form and complete the custodian’s details. Leave the signature blank.

Visit a notary public

IRCC’s wording is ‘notarized (certified by a lawyer or notary)’, so book with us and we’ll make sure a notary public handles it.

Sign and send

Sign in front of the notary. Then send the notarized page to the family so it goes in with the parents’ notarized page.

What to bring

  • The IMM 5646 with the custodian page completed and unsigned
  • Valid government photo ID
  • Proof you are a Canadian citizen or permanent resident (passport, citizenship certificate or PR card)

Avoid these common mistakes

  • Having it signed by a commissioner only. IRCC asks for this form to be notarized by a notary or lawyer.
  • Sending only one page. IRCC needs both the custodian’s and the parents’ notarized pages.
  • Signing before you arrive. Sign only in front of the notary.

Frequently asked questions

Who can be a custodian?

An adult who is a Canadian citizen or permanent resident. Check IRCC’s minor children study page for the full requirements.

Can you notarize the parents’ page too?

The parents’ page is meant to be notarized in the parents’ home country. If the parents are in Ontario, contact us and we’ll advise.

Do students 17 or older need it?

It’s required for children under 17. At 17 or older it’s only needed if an officer asks for it.

How long does it take?

Usually about 10–15 minutes once you are with the notary.
