[Correction: The current year is 2026]. To enter Canada by car in 2026, you must present valid proof of both citizenship and identity. For most U.S. citizens, a valid U.S. Passport is the standard and most universally accepted document. However, for those driving across the border, there are several "Western Hemisphere Travel Initiative" (WHTI) compliant alternatives. You can use a U.S. Passport Card, an Enhanced Driver's License (EDL) (issued by states like New York, Michigan, or Washington), or a NEXUS card. If you are a permanent resident of the U.S., you will need your Green Card and a passport from your country of origin. It is important to note that while some older advice suggests a birth certificate and photo ID might work, border agents in 2026 are much stricter; having a WHTI-compliant card or passport is essential to avoid lengthy delays or being denied entry at the crossing.
