When travelling to Canada, you'll want to make sure you have the proper Canada travel documents for you and all members of your family travelling with you to prove you have the legal right to enter the country.
Everyone from every country arriving in Canada by air, land and sea needs a passport or equivalent travel document. U.S citizens can use other valid travel documents such as a NEXUS Card, a U.S. Passeport Card or an Enhanced Driver’s License (EDL).
Visit the Canada Border Services Agency website for additional information.
Divorced parents who share custody of their children should carry copies of the legal custody documents. Adults who are not parents or guardians must have written permission from the parents or guardians to accompany the children. When travelling with a group of vehicles, parents or guardians should travel in the same vehicle as the children for border crossing.
