Passport required to visit Canada

Passport required in 2010 for those 16 and older.

As of June 2009 all travelers to Canada are now required to present a passport to re-enter the United States. If you are traveling by automobile, a less expensive passport card is also available. This requirement does not affect children under 16 crossing by land; they can continue to enter with an original birth certificate.
A passport card cost only $45 verses $100 for the traditional passport book, but can only be used for land crossings into Canada or Mexico. Both passports are valid 10 years for adults and simplify border crossing and the process is simple. All you need is a birth certificate and valid driver’s license to apply.
A passport is an internationally recognized travel document that verifies the identity and nationality of the bearer. Only the U.S. Department of State has the authority to grant, issue or verify United States passports. The Department of State designates the United States Postal Service to accept passport applications on its behalf.
Applying for a U.S. Passport – You need to apply in person if you are applying for a U.S. passport for the first time; if your expired U.S. passport is not in your possession; if your previous U.S. passport has expired and was issued more than 15 years ago; or if your previous U.S. passport was issued when you are under 16 your currently valid U.S. passport has been lost of stolen.
What you need - You’ll need a certified birth certificate (needs a raised, embossed, highlighted or multi-colored seal) from county or state government (not a hospital document). AND a current, valid Driver's license, Government ID State ID or military ID
