When you land at the airport, you will have to go through a Customs check and hand in your Customs form before you are allowed to leave the airport. Similarly, at a border crossing, you will not be allowed to cross into Canada until you pass a Customs check and hand in the Canada Customs form. The Canada Customs staff may ask you questions about the information on your form. They may ask you to produce receipts. They can search your luggage and in some cases, they can even search you! It is very important that you be absolutely honest and accurate about what you are bringing back to Canada. You can get into very serious trouble if you are dishonest. Last Reviewed: August 2012
