American & Canadian Passport Requirements and Changes
U.S. citizens must carry proper identification when entering Canada, such as a valid U.S. passport.
All visitors arriving from or transiting through the U.S. are encouraged to visit the U.S. Customs and Border Protection website for information concerning the U.S. Western Hemisphere Travel Initiative, and the requirements to enter or return to the U.S.
NEXUS or FAST Programs
Citizens of the U.S. who are members of the NEXUS program may present their membership card as proof of identification and as a document that denotes citizenship, when arriving by air (when coming from the U.S.), land, or marine modes.
Citizens of the U.S. who are members of the FAST program may use their cards as proof of identity when arriving by land and marine modes only.
Permanent residents of the U.S. who are members of the NEXUS or FAST programs must travel with a passport and proof of permanent residence, and may be asked to present these documents to the officer upon arrival at the border.
Permanent residents of the U.S. who are members of NEXUS also need an Electronic Travel Authorization (eTA) when flying to or transiting through Canada. Citizens of the U.S. and Canada are exempted.
