At Harmon Travel  we try to avoid any unpleasant surprises and although the following information probably is not applicable to you, we would like to advise you about a Canadian law that may deny travelers entrance into Canada if they have ever been convicted of a criminal offense. The list of inadmissible classes includes those who have been convicted of:

A minor offense (including shoplifting, theft, assault, possession of an illegal substance, etc.)

An “indictable” criminal offense (including assault with a deadly weapon, manslaughter; etc.), or

Driving While Intoxicated (DWI).

If any of these situations apply to you, we recommend you get in touch with the nearest Canadian Embassy or Consulate General as soon as possible to ensure a smooth entry into Canada.

Here is a current description of the Canadian entry rules as per the US State Department website.

CANADA - Passport or proof of U.S. citizenship such as a birth certificate, naturalization certificate, and photo ID required. Minors (under 16) traveling alone or in someone else’s custody must present written authorization, signed before a notary, from the parent(s) or guardian. Visas are not required. Canadian immigration officials at ports of entry will issue persons planning to stay longer than 180 days a visitor’s record. Anyone with a criminal record (including a DWI charge) should contact the Canadian Embassy or nearest Consulate General before travel. U.S. citizens entering Canada from a third country must have a valid passport. HIV testing required for resident applicants who are over 15. A temporary resident applicant requires immigration medical examination if stay exceeds 6 months or seeking to work in Canada. For student or business travel, check with the Canadian Embassy, 501 Pennsylvania Ave., NW, Washington, DC 20001 (202/682-1740) or the nearest Consulate General: CA (213/346-2701), MI (313/567-2085), NY (212/596-1700 or 716/858-9501), or WA (206/443-1375
