Entry into Canada: Canadian law requires that all persons entering Canada carry proof of citizenship and identity. A valid U.S. passport, passport card, or NEXUS card satisfies these requirements for U.S. citizens. Children under 16 only need proof of U.S. citizenship.

To enter Canada in 2026, the required documents depend on your citizenship and mode of travel. U.S. Citizens traveling by air must have a valid U.S. Passport; if traveling by land or sea, they can use a Passport Card or an Enhanced Driver's License (EDL). U.S. Permanent Residents (Green Card holders) must carry their valid Green Card and their passport from their country of nationality for all modes of travel. International travelers from "visa-exempt" countries (like the UK, Australia, or EU nations) need a valid passport and an Electronic Travel Authorization (eTA) if flying into Canada, though an eTA is not required for land/sea entry. Travelers from "visa-required" countries must apply for a Temporary Resident Visa (TRV) in advance. All visitors should be prepared to show proof of sufficient funds and a return itinerary. It is also important to note that as of 2026, Canada has modernized its "ArriveCAN" system, and while no longer strictly mandatory for health, it is the fastest way to submit your customs and immigration declaration digitally before you land.
