Last Updated May 14, 2025

Minors crossing the US-Canada border typically require a valid passport or a NEXUS card for identification. If traveling without parents or legal guardians, a notarized letter of consent is often necessary to prove permission for international travel. It is essential to check specific airline and border agency requirements prior to travel to avoid delays.

What Documents Does a Minor Need to Cross the US-Canada Border?

Number Name Description
1 Passport (minor) Minors traveling across the US-Canada border must have a valid passport as the primary identification document, ensuring compliance with both countries' border security requirements. A passport provides verified proof of citizenship and identity, which is essential for smooth border crossing and avoiding delays.
2 Birth Certificate (minor) Minors crossing the US-Canada border typically require a valid birth certificate as proof of citizenship, which must be an original or certified copy issued by the appropriate government authority. This document verifies the minor's identity and parentage, ensuring compliance with border security regulations.
3 Parental Consent Letter Minors crossing the US-Canada border must carry a notarized parental consent letter specifying the names of the accompanying adults, travel dates, and destinations to verify authorization from non-accompanying parents or guardians. This document helps border officials ensure the child's safe and lawful travel, preventing custody disputes or unauthorized movement across international boundaries.
4 Custody Documents (if applicable) Minors crossing the US-Canada border may need custody documents such as notarized permission letters from the non-accompanying parent(s) or legal guardians to prove authorization for travel. These documents help border officials verify custodial consent and prevent custody disputes during cross-border travel.
5 Visa (if required by nationality) Minors crossing the US-Canada border must present a valid passport, and depending on their nationality, a visa or an Electronic Travel Authorization (eTA) may be required to enter either country. Canadian citizens typically do not require a visa to enter the US, while minors from visa-exempt countries may need an eTA when flying to Canada, and non-exempt nationals must obtain the appropriate visa before travel.
6 NEXUS Card (if enrolled) Minors enrolled in the NEXUS program require their NEXUS card as the primary document to cross the US-Canada border, streamlining the entry process and accelerating border clearance. In the absence of a NEXUS card, minors must carry a valid passport and may need additional consent forms or documentation depending on the travel circumstances.
7 Permanent Resident Card (if applicable) Minors crossing the US-Canada border must carry a valid passport or a birth certificate along with a Permanent Resident Card (PR Card) if they hold permanent resident status in either country. The PR Card serves as proof of lawful permanent residency and is essential for re-entry, ensuring smooth border processing for minor travelers.
8 U.S. Citizenship Certificate (if applicable) Minors crossing the US-Canada border must present a valid U.S. Citizenship Certificate if they are U.S. citizens without a birth certificate or passport, serving as proof of their citizenship status. This document is essential for verifying identity and nationality, especially for minors traveling without parents or legal guardians.
9 Trusted Traveler Program Card (if applicable) Minors crossing the US-Canada border typically need a valid passport or a trusted traveler program card such as NEXUS, which expedites processing for pre-approved, low-risk travelers. The NEXUS card serves as an efficient identification method, allowing minors to use dedicated lanes and reducing wait times during border crossing.
10 Travel Authorization (for flights, if required) Minors traveling between the US and Canada by air may require a travel authorization, such as a notarized letter of consent from a parent or legal guardian, outlining permission for the trip and details of the accompanying adult. Airlines and border officials often mandate this document to verify guardianship and prevent child abduction, ensuring smooth processing at the border.
11 Guardian/Chaperone ID Minors crossing the US-Canada border must present valid identification along with proof of guardianship or authorization from a parent or legal guardian, such as a notarized consent letter. Guardians or chaperones are required to carry their own government-issued photo ID and documents verifying their relationship to the minor to ensure smooth border crossing.
12 Adoption Papers (if applicable) Minors crossing the US-Canada border must present valid identification, such as a passport or enhanced driver's license, and if the child is adopted, original adoption papers or a certified copy must be carried to prove legal guardianship. These documents ensure smooth border crossing by verifying the minor's legal status and relationship to the accompanying adult.
13 Health Consent/Medical Authorization Letter Minors crossing the US-Canada border require a Health Consent or Medical Authorization Letter signed by a parent or guardian to authorize medical treatment in emergencies. This document should include the minor's personal details, the accompanying adult's information, and specific medical permissions to ensure prompt healthcare access.

These letters are needed primarily when a minor travels without both parents or legal guardians present, serving as proof of permission to cross the border.

Flyers and Travel Agencies Travel agencies may provide additional documentation guidelines or services for minors traveling unaccompanied across the border.

Additional Requirements for Children Traveling with One Parent

What additional documents does a minor need when traveling with one parent across the US-Canada border? Minors traveling with only one parent must carry a consent letter from the non-accompanying parent. This letter should include contact information and authorization details to avoid delays at the border.

Special Cases: Grandparents, Relatives, and Guardians

Minors crossing the US-Canada border with grandparents, relatives, or guardians require specific documentation beyond a standard passport or birth certificate. These special cases often demand additional consent forms to prove legal authorization for travel.

Guardians must provide a notarized letter of permission from the minor's parents, including contact information and travel details. Grandparents or other relatives should carry evidence of their relationship to the child, like a birth certificate, along with the written consent from parents or legal guardians.

CBP and Canadian Border Services Enforcement Policies

Minors crossing the US-Canada border must carry proper identification and documentation as required by US Customs and Border Protection (CBP) and Canadian Border Services Agency (CBSA). These agencies enforce strict policies to ensure the safety and legal compliance of all travelers, especially children.

For US citizens under 16, CBP typically requires proof of US citizenship, such as a birth certificate or a passport. If the minor is traveling without both parents or legal guardians, a notarized consent letter is strongly recommended to avoid delays. Canadian enforcement policies also emphasize the importance of authorized travel documents and may request additional proof of guardianship or custody during entry inspections.
