If you are planning to go to Canada, it is important to remember that since June of 2009 everyone from for every country in the world, including the United States, needs a passport or an equivalent travel document to enter Canada. In the past, U.S. citizens did not need a passport to enter Canada. Visitors from any other country have always been required to show a passport in order to enter Canada. Due to heightened security measures to strengthen border security under the Western Hemisphere Travel Initiative, standardized travel documentation has been top priority. As a result, the use of a passport or equivalent travel document is mandatory.
