A consent letter demonstrates that a child has permission to travel outside Canada from every parent or guardian who is not accompanying them on the trip. There is no Canadian legal requirement for children to carry a consent letter.Parental consent documentation for travel to Canada and Mexico. Child's Information: The form includes the child's full name, date of birth, place of birth, and passport or identification details. Our form wizard will help you and your family know what passport form(s) to use. The intention of this letter is to provide consent for a minor child to travel without the company of both legal parents. The wizard is not an online application, and completing the wizard does not mean you will receive a passport. If one or both parents are not accompanying the child, bring a letter from any parent or legal guardian not present giving permission to cross the border. Always use the information exactly as it appears on your passport (to book and fill out any documents). A valid photo I.D. is required of the guardian picking up a child guest and the Guardian must be listed on the guardian contact form.
