These secure documents denote Canadian identity and citizenship for the purpose of cross-border travel to the U.S. A at land and water ports of entry. They are an alternative document to the Canadian passport. An enhanced driver's license or EDL can allow a U.S.
citizen to visit Canada for both leisure and business purposes. However, enhanced driver's licenses are only valid for land and sea crossings, so you won't be able to fly to Canada with them as your only form of identification. Consequently, when an American tries to drive to Canada with an improved driver's license, it's easy for border security officers to flag him for a previous DUI. Regardless of whether you are using a U.S.
passport or an enhanced driver's license to cross the Canadian border, a DUI or similar offense, such as DWI or OWI, can make you criminally inadmissible in the country and result in you being denied entry to the border. Americans with an Enhanced Identification Card (EIC) or Enhanced Driver's License (EDL) from the State of Washington, Minnesota, South Dakota, Michigan, New York, or Vermont can travel to Canada without a passport.
