It is the sole prerogative of every country or territory to determine who is allowed to enter or exit. Canadian consular officials cannot intervene on your behalf if you do not meet entry or exit requirements. The following information has been obtained from American and is subject to change at any time. The country- or territory-specific entry/exit requirements are provided on this page for information purposes only. While every effort is made to provide accurate information, information contained here is provided on an "as is" basis without warranty of any kind, express or implied. The Government of Canada assumes no responsibility, and shall not be liable for any damages in connection to the information provided. It is your responsibility to check with Embassy of the United States of America or one of its consulates for up-to-date information.

Providing additional information at borders
Travellers entering the U.S. by air or by sea are required to provide additional information, such as their address while in the U.S., including U.S. territories. They may also be asked for evidence of residential, employment or educational ties to Canada, proof that the trip is for a legitimate purpose and is of a reasonable length, and proof of financial support while in the country.
More information on border security programs currently in force in the U.S. is available from the U.S. Customs and Border Protection.
Some Canadians may have U.S. as well as Canadian citizenship through birth in the U.S. or through naturalization or descent. Under the Western Hemisphere Travel Initiative, U.S. citizens are required to present a valid U.S. passport to enter or re-enter the U.S. by air. Although U.S. authorities do not formally require dual nationals to carry both a U.S. and a Canadian passport, carrying both documents as proof of citizenship may facilitate both entry into the U.S. and returning to Canada.
Consult Laws and Culture for more information.
Canadian retirees seeking to winter in warmer climates will likely receive a maximum admission period of six months. Those who wish to stay longer may apply for an extension with U.S. Citizenship and Immigration Services before their authorized stay expires.
If you have a criminal record, no matter the severity or the date of the offence, you may be refused entry to the U.S. You may also experience problems when travelling through U.S. airport facilities. A pardon for an offence issued by Canadian authorities is not recognized under U.S. law for the purpose of entry into the U.S. If you have a criminal record, you should contact one of the U.S. Citizenship and Immigration Services ports of entry by telephone or contact the Embassy of the United States of America or one of its consulates well in advance of your departure from Canada. If you are ineligible to enter the U.S., you may apply for a waiver of ineligibility. This will involve completing Form I-192, "Advance Permission to Enter the U.S. as a Non-Immigrant." There is a fee and it may take several months to process your application. Waiver application forms are available from any port of entry to the U.S., any preclearance site in Canada, and the Embassy of the United States of America or one of its consulates in Canada. A list of designated ports of entry that accept filings of waiver applications as well as the application form are available from the U.S. Customs and Border Protection.
U.S. ports of entry are computerized and connected to a centralized database. Information is readily available on criminal convictions in both Canada and the U.S. Even though you may have entered the U.S. without hindrance in the past, you could run into difficulty if your record shows a criminal conviction or a previous denial of entry. Attempting to gain entry without a waiver could result in several weeks of detention and a permanent bar from entering the U.S.
If you are an American citizen that left the U.S. to avoid military service and have not since regularized your status, there might be an outstanding warrant for your arrest or you might be ineligible for U.S. entry. If in doubt, check with the nearest U.S. Citizenship and Immigration Services port of entry. If you need information about regularizing your status with the U.S. military, contact the Embassy of the United States of America.
Children and travel
Children need special documentation to visit certain countries. See Children for more information.
If you have an unusual situation concerning entry into the U.S., you should obtain authoritative information from the U.S. authorities immediately before your visit. For more information, consult the Embassy of the United States of America or U.S. Customs and Border Protection.
For more detailed information on entry requirements for the U.S., consult our Travel Advice and Advisories page for the United States.
