Monty Ray Turner, 51, did not speak at the Immigration and Refugee Board hearing, and his lawyer did not argue against a move to send Turner back to the U.S. to face criminal charges.
"At this time, he just wishes to emphasize that the allegations are not admitted," Leslie Heinrichs said.
"He wishes to return to the United States as soon as possible to face the charges against him."
Turner was ordered deported under a section of law that says foreigners cannot be admitted to Canada if they face criminal charges elsewhere that would carry a maximum sentence in Canada of 10 years or more.
Immigration and Refugee Board member Michael McPhalen agreed with a lawyer for the Canada Border Services Agency who said Turner's alleged crimes, including burglary, would carry a maximum penalty of life in prison in Canada.
"I am satisfied that there are reasonable grounds to believe that you are a foreign national who is inadmissible on grounds of serious criminality," McPhalen ruled.
What remained unclear Friday is how Turner managed to cross the border into Canada, despite being the subject of arrest warrants and a court order prohibiting him from contacting the his son.
Turner is accused of breaking into the home of Brandy Turner in Longmont, Colo. on May 25, blasting her with a stun gun and pepper spray and kidnapping the couple's three-year-old son, Luke.
Turner was already under a court order prohibiting him from contacting his wife or son after disappearing with the boy for eight months in 2012.
Police tracked down Turner in Brandon, Man. the following day, after he used a credit card to check into the Casablanca Motor Inn. He surrendered peacefully. Luke was taken into care by a child services agency and later reunited with his mother.
Turner faces charges in the United States that include second-degree burglary, second-degree kidnapping, menacing, violation of a custody order, third-degree assault and child abuse.
He had been kept in custody since his arrest but had asked to be allowed to stay in a motel instead of the Winnipeg Remand Centre. The board refused, deeming him a flight risk.
There was no indication Friday when Turner would be deported. The federal government normally does not release such information.
