A Canadian Child Travel Consent Letter is a document signed by the non-accompanying parent(s) or legal guardian(s) authorizing a minor to travel internationally with only one parent, a relative, or another designated adult. The Canada Border Services Agency (CBSA) strongly recommends this letter for any child crossing the Canadian border without both parents present, and border officers at Canadian ports of entry and foreign customs agencies may request it at their discretion.

While no specific Canadian statute mandates a travel consent letter, the document serves a critical child protection function. CBSA officers are trained to identify potential child abduction — Canada is a signatory to the Hague Convention on the Civil Aspects of International Child Abduction (implemented through provincial legislation such as Ontario's Children's Law Reform Act, R.S.O. 1990, c. C.12, Part III). A consent letter demonstrates that the child's travel has been authorized by the custodial parent(s), reducing the risk of border delays, secondary inspections, or denial of entry.

The letter is particularly important in separated or divorced families where custody arrangements may restrict one parent's ability to travel with the child. A custody order or separation agreement that limits travel authority should be carried alongside the consent letter. Without a consent letter, a parent or guardian travelling alone with a child may face extended questioning by CBSA officers, foreign immigration authorities, or airline security personnel — potentially resulting in missed flights or denied boarding.

A Canadian Child Travel Consent Letter is needed whenever a child under 18 will cross an international border without both parents present. The most common scenario is a child travelling with one parent on a vacation, family visit, or school trip — the non-travelling parent should sign a consent letter authorizing the specific trip.

This letter is essential when a child travels with a grandparent, aunt, uncle, family friend, school teacher, sports coach, or group leader. Both parents should sign the consent letter in this situation, as neither parent is accompanying the child. School field trips, sports tournaments, music competitions, and religious pilgrimages that cross international borders all require consent documentation.

Separated or divorced parents face heightened scrutiny at border crossings. If a custody order or separation agreement restricts the child's travel — for example, requiring both parents' consent for international travel — the consent letter must align with those court-ordered restrictions. Travelling in violation of a custody order can constitute a criminal offence under the Criminal Code (R.S.C. 1985, c. C-46, s. 282 — abduction by parent in contravention of custody order).

The letter is also recommended for domestic travel within Canada when a child is travelling with a non-parent adult, particularly by air. Canadian airlines may request proof of parental authorization, especially for unaccompanied minor programs. For children with different surnames than their travelling parent, the consent letter combined with a birth certificate helps explain the relationship at security checkpoints.

A properly prepared Canadian Child Travel Consent Letter must include the child's full legal name as it appears on their passport, date of birth, Canadian passport number, and place of birth. For multiple children travelling together, each child should be individually identified with their own passport details.

The authorizing parent(s) must provide their full legal names, home addresses, telephone numbers, email addresses, and their relationship to the child. Both parents should sign if the child is travelling with a non-parent adult; the non-travelling parent signs if the child is travelling with the other parent. The signature should be witnessed or notarized — while not legally required, notarization significantly increases the letter's credibility with border officers and foreign authorities.

The travel companion (the adult accompanying the child) must be identified with their full name, date of birth, passport number, relationship to the child, home address, and contact telephone number. The travel itinerary must specify the destination country or countries, departure and return dates, flight numbers or travel route, and accommodation addresses.

An emergency contact section should include at least one person who can be reached 24 hours a day during the trip — typically the non-travelling parent. Include the child's health insurance information (provincial health card number and any private travel medical insurance policy number) and any relevant medical information (allergies, medications, or conditions). The CBSA recommends also carrying the child's birth certificate and any applicable custody orders or guardianship documents as supporting evidence alongside the consent letter.
