Visas are not needed by U.S., Canadian, Irish, Australian, New Zealand, or British citizens for visits of less than 3 months. You do need a valid passport unless you're a citizen of another E.U. country (in which case, you need only an identity card, although we always recommend that you carry a passport anyway).
Safeguard your passport in an inconspicuous, inaccessible place like a money belt. If you lose it, visit the nearest consulate of your native country as soon as possible for a replacement.

You'll be charged a flat rate of duty on the next $1,000 worth of purchases. Any dollar amount beyond that is subject to duty at whatever rates apply. On mailed gifts, the duty-free limit is $200. Be sure to have your receipts or purchases handy to expedite the declaration process. Note: If you owe duty, you are required to pay on your arrival in the United States, using cash, personal check, government or traveler's check, or money order; some locations also accept Visa or MasterCard.
To avoid having to pay duty on foreign-made personal items you owned before your trip, bring along a bill of sale, insurance policy, jeweler's appraisal, or receipt of purchase. Or you can register items that can be readily identified by a permanently affixed serial number or marking -- think laptop computers, cameras, and CD players -- with Customs before you leave. Take the items to the nearest Customs office, or register them with Customs at the airport from which you're departing. You'll receive, at no cost, a Certificate of Registration, which allows duty-free entry for the life of the item.

All valuables, including serial numbers of valuables you already own, such as expensive foreign cameras, should be declared on the Y-38 form before departure from Canada. Note: The C$750 exemption can only be used once a year and only after an absence of 7 days.
