While a passport is the most recommended document for all international travel, U.S. citizens have several alternative options for entering Canada by land or sea in 2026. If you are driving across the border or arriving by boat, you can use an Enhanced Driver’s License (EDL), which is currently issued by states like Washington, Michigan, Minnesota, New York, and Vermont. Other valid documents include a U.S. Passport Card, a NEXUS card, or a FAST card. Indigenous persons registered under the Indian Act can also use their Certificate of Indian Status. However, it is vital to remember that if you are traveling by air, a valid international passport is strictly required for all travelers regardless of age. If you attempt to fly without one, the airline will deny you boarding, as they are legally obligated to verify a passport for international flights.
