Children under the age of 18 need the permission of both parents to travel alone or with just one parent.
The Government of Canada strongly recommends that Canadian children carry a consent letter if they are travelling abroad alone, with only one parent/guardian, with friends or relatives or with a group. For more information on the documents required, see the Government of Canada website.
Airlines also offer an accompaniment service for unaccompanied minors. We invite you to contact your air carrier to find out more.
