Do I need the other parent's permission to travel internationally with my child?

Yes. Taking a child out of Canada typically requires either written consent from all parents with parenting rights or a court order authorizing the travel. Canadian Border Services Agency recommends carrying a signed consent letter when travelling internationally with a child, especially if only one parent is travelling.

A consent letter should include: both parents' names, the child's full name and date of birth, the travel destination, travel dates, contact information for the non-travelling parent, and both parents' signatures (ideally notarized). While not always legally required, border officers can and do ask for evidence that the other parent has consented.

Check your parenting order or separation agreement — many specifically require consent for international travel or restrict travel to certain regions. Travelling in breach of a court order can have serious consequences, including being required to return the child immediately.

Obtaining a passport for a minor in Canada also generally requires consent from both parents with custody or parenting rights. If one parent refuses to consent to a passport, the other can apply to a court for an order.
