Under the Western Hemisphere Travel Initiative, as of January 23, 2007, citizens of both Canada and the United States were required to present a valid passport at a U.S. Preclearance Facility — located at all major Canadian airports — prior to boarding their flight to the United States. Beginning June 1, 2009, it was established that travelers entering the U.S. through a land or sea border must present a passport or WHTI-compliant document.

It is strongly recommended that all citizens of both Canada and the United States carry passports when crossing the U.S./Canada border. All persons, whether U.S. Citizens or foreign nationals, must present a valid passport or alternate approved travel document to enter or depart from the United States by air.

Western Hemisphere Travel Initiative
The Western Hemisphere Travel Initiative (WHTI) was mandated by Congress in the Intelligence Reform and Terrorism Prevention Act of 2004 to strengthen border security and facilitate entry into the United States for citizens and legitimate international visitors. WHTI requirements for air travel took effect on 23 January 2007.
Since implementation, U.S. Customs and Border Protection has and will continue to exercise its current authorities in unique circumstances to allow individuals subject to the WHTI requirements into the United States based on other evidence of identity and citizenship.
Travel document security remains a top priority for the U.S. Government. Both the 9/11 Commission and the U.S. Congress urged strengthening of travel documents to prevent entry of terrorists across our borders, reduce use of fraudulent documents, and speed up entry procedures.
