As of June 1, 2009, U.S. citizens must provide one of the following travel documents when travelling by land or sea between the U.S. and Canada: U.S. Passport, U.S. Passport Card, Enhanced Driver's License, or Trusted Traveler Program Cards.
Accepted for international travel by air, land, and sea, the U.S. Passport validates identity and nationality.
Valid only for travel by land and sea, this limited-use document costs less than a U.S. Passport and can conveniently fit in your wallet.
Designed for travel from Canada into the U.S., this special driver's license verifies identity and citizenship.
Valid for travel by land or sea, these NEXUS, SENTRI or FAST enrollment cards are available only to pre-approved, low-risk travelers for speedy entry into the country.
U.S. and Canadian citizen children under age 16 who arrive by land or sea from contiguous territory may instead provide an original or copy of a her birth certificate, a Consular Report of Birth Abroad, a Naturalization Certificate, or a Canadian Citizenship Card.
