Customs & Duty...
If you are a citizen of the United States, you do not need a passport to enter into Canada or the U.S when travelling by land or sea. However, you should carry proof of your citizenship, such as a birth certificate, certificate of citizenship or naturalization, as well as a photo ID. If you are a permanent resident of the U.S., you should bring your Permanent Resident Card (i.d. green card) with you.

Effective January 8, 2007 US citizens travelling by air between the United States and Canada will be required to present a valid US passport, Air Nexus card, or US Coast Gaurd Merchant Mariner Document.

Duty-Free Limits for Visitors Returning to U.S.
U.S. residents returning to the United States after 48 hours can take back $400 US worth of merchandise duty free every 30 days. After a visit of less than 48 hours or if the $400 allowance or part of it has been used within the previous 30 days, an exemption of $200 U.S. is allowed.

Members of a family travelling together may combine their personal exemptions except in the case of the $200 exemption. Articles brought back into the U.S. as part of an exemption must be for personal or household use. They must be brought with the person and properly declared. They must not be prohibited or restricted items. The duty charged varies on the country the article was made in and the type of article.
