Western Hemisphere Travel Initiative
Created in 2004, the Western Hemisphere Travel Initiative (WHTI) was created as part of the Terrorism Prevention Act, requiring both Canada and the United States to show proper forms of identification when traveling between the two.
When traveling by air, a valid passport must be presented for children and adults of all ages.
Land and Sea Travel
When traveling by land or sea, travelers may present a passport, passport card or WHTI compliant travel document.
WHTI Compliant Documents
Trusted traveler's cards, enhanced driver's license, enhanced tribal cards, U.S. military identification, U.S. merchant mariner and Native American or American Indian cards are all valid WHTI documents and may be used between land and sea travel.
Children under the age of 16 traveling between the United States and Canada can submit a valid birth certificate when traveling by land or sea. When traveling by air, children of all ages are required to hold a valid passport.
