Border Crossing:
United States visitors require proof of citizenship: birth certificate, driver's licence or passport. You must have proof of citizenship and photo ID. When entering Canada, you are allowed to bring a 40 oz. bottle of liquor OR a case of beer, plus one carton of cigarettes per person. No handguns or semi-automatic weapons under 26" in length are permitted, and all weapons of all types must be declared. If you are bringing children, other than your own, across the border, bring a letter of authorization and proper ID.

New (2007) Canadian / American Border Crossing Passport Requirements
This is taken directly from the US State Departments website. Please plan your trip accordingly.
Under the Western Hemisphere Travel Initiative (WHTI)
The proposed implementation timeline has two phases:
Beginning January 23, 2007, ALL persons, including U.S. citizens, traveling by air between the United States and Canada, Mexico, Central and South America, the Caribbean, and Bermuda will be required to present a valid passport, Air NEXUS card, or U.S. Coast Guard Merchant Mariner Document, or an Alien Registration Card, Form I-551, if applicable.
As early as January 1, 2008, ALL persons, including U.S. citizens, traveling between the U.S. and Canada, Mexico, Central and South America, the Caribbean, and Bermuda by land or sea (including ferries), may be required to present a valid passport or other documents as determined by the Department of Homeland Security. While recent legislative changes permit a later deadline, the Departments of State and Homeland Security are working to meet all requirements as soon as possible. Ample advance notice will be provided to enable the public to obtain passports or passport cards for land/sea entries.
The passport requirement does NOT apply to U.S. citizens traveling to or returning directly from a U.S. territory. U.S. citizens returning directly from a U.S. territory are not considered to have left the United States and do not need to present a passport. U.S. territories include the following: Guam, Puerto Rico, the U.S. Virgin Islands, American Samoa, Swains Island, and the Commonwealth of the Northern Mariana Islands.
