If a child is travelling to or from Canada without both parents — with one parent, a grandparent, a friend's family, or alone — border officers may ask for proof that the trip is authorized. That proof usually comes in the form of a consent letter. It isn't always a strict legal requirement in every case, but it's widely recommended, and travelling without one can lead to real delays or, in some circumstances, being denied entry or exit.
Here's what a consent letter is for and when it's worth having one.
Why Consent Letters Matter at the Border
Border officers — both Canadian and foreign — are alert to the possibility of child abduction or unauthorized travel. A consent letter gives them a quick way to confirm that a child's travel has been authorized by the people who have legal authority over the child, without needing to investigate on the spot. Even where it isn't strictly mandated by law for a given trip, having one reduces the chance of being questioned, delayed, or in rare cases refused entry or exit.
When a Consent Letter Is Recommended
| Travel situation | Generally recommended? |
|---|---|
| Child travelling with both parents/guardians | Not usually necessary |
| Child travelling with only one parent | Yes — a letter from the non-travelling parent is recommended |
| Child travelling with a grandparent, relative, or family friend | Yes — a letter from both parents/guardians is recommended |
| Child travelling alone (e.g., unaccompanied minor) | Yes, strongly — from all parents/guardians with legal authority |
| Child travelling as part of a school or group trip | Yes — group organizers commonly require one regardless of border rules |
Whether a letter is legally required for a specific trip can depend on the countries involved (both the departure and destination countries have their own expectations), so the practical guidance is the same either way: bring one whenever a child is travelling without both parents or guardians.
What a Consent Letter Should Include
- [ ] Child's full name and date of birth
- [ ] Names and contact information of both parents/guardians (or all individuals with legal custody or decision-making authority)
- [ ] Name of the accompanying adult, if any, and their relationship to the child
- [ ] Travel dates and destination(s)
- [ ] A clear statement that the non-travelling parent(s)/guardian(s) consent to the trip
- [ ] Signature(s) of the consenting parent(s)/guardian(s), ideally dated close to the travel date
- [ ] Contact information for the consenting parent(s) in case a border officer wants to verify
Some families also have the letter notarized or otherwise formally witnessed, which can add credibility, though it isn't universally mandated — check the expectations of both the departure and arrival countries if you want extra certainty.
Do You Legally Need One?
Canada doesn't have a single blanket law requiring every child crossing the border to carry a consent letter in every scenario. What it does have is a strong, consistent recommendation from border authorities, paired with the practical reality that officers can ask questions or request documentation when a child is travelling without both parents. In situations involving a custody dispute, a court order restricting travel, or a parent who has withheld consent, the stakes are higher — a consent letter doesn't override an existing court order, and travelling in violation of one can have serious legal consequences separate from any border issue.
What Border Officers May Ask For
Beyond the consent letter itself, officers may also want to see:
- Proof of the accompanying adult's relationship to the child (if not obvious)
- The child's own travel and identity documents
- In some cases, proof of the travelling parent's or guardian's own status or identity
If you're a family lawyer's client with a custody order in place, it's worth carrying a copy of the relevant order alongside any consent letter, in case questions arise about travel permissions.
Frequently asked questions
Does the consent letter need to be notarized to be valid?
Not necessarily — a signed letter is often sufficient, but notarization can add credibility and some destination countries expect it. If you want the strongest possible document, having it notarized is a reasonable extra step.
What if the other parent won't sign a consent letter?
If a parent refuses or is unreachable, this can become a family law issue rather than a simple paperwork gap — particularly if there's an existing custody arrangement. This is a good time to speak with a family lawyer rather than attempting to travel without resolving it.
Is a consent letter required for a child travelling with one parent on a short trip?
It's recommended even for short trips with one parent, since officers can't tell in advance how long a trip will be or ask follow-up questions on the spot. Having the letter ready avoids any friction.
Does a consent letter expire?
There's no fixed government-set expiry, but it's good practice to date it close to the actual travel and to prepare a fresh one for each trip rather than reusing an old letter indefinitely.
