Canadian officials knew Omar Khadr was sleep-deprived for weeks to make him more willing to talk for an interrogation, a newly released document shows.

According to the internal report from the Foreign Affairs department, Canadian official Jim Gould visited Khadr on March 30, 2004 in Guantanamo Bay and was told that measures were taken to make him "more amenable and willing to talk."

Dated April 20, 2004, the report — written by R. Scott Heatherington, who was the director of the department's Foreign Intelligence Division — states Gould was told Khadr was placed on a "frequent flyer program" for three weeks before Gould's visit. That meant Khadr was "not permitted more than three hours in any one location."

"At three-hour intervals, he is moved to another cell block, thus denying him uninterrupted sleep," according to the report. "He will soon be placed in isolation for up to three weeks, and then he will be interviewed again."

But Khadr did not appear to be much affected by the sleep deprivation, according to the documents.

"He did not yawn or indicate in any way that he was tired throughout the two-hour interview. It seems likely that the natural resilience of a well-fed and healthy 17-year-old [is] keeping him going."

The document reveals that during the interview with Gould, Khadr refused to answer questions, but was "smiling broadly — he was enjoying the exchange."

According to Heatherington, Gould described Khadr as a thoroughly "screwed up" young man.

"All those persons who have been in positions of authority over him have abused him and his trust, for their own purposes," the report says. "In this group can be included his parents and grandparents, his associates in Afghanistan and fellow detainees in Camp Delta and the U.S. military."

Heatherington also described an incident with a U.S. Defense Department interrogator in which Khadr was shown a picture of his family, but denied knowing anyone in the photo.

Heatherington said when he was left alone with the picture, he urinated on it. When MPs cleaned him and the picture up and left him alone, he urinated on it again.

When he was cleaned up again and "probably assuming that he was no longer being watched, [Khadr] laid his head down on the table beside the picture in what was seen as an affectionate manner."

Khadr is at the U.S. naval base in Cuba awaiting trial before a military commission on charges that he murdered a U.S. army sergeant in Afghanistan in 2002, when he was 15.

The documents released Wednesday to the media by Khadr's lawyers follow a Supreme Court decision in May that Khadr has a constitutional right to see certain videos and documents held by Foreign Affairs, the RCMP and CSIS.

The items relate to interviews Canadian officials conducted with Khadr during his detention at the U.S. naval base in Cuba in 2003 and 2004.

The Supreme Court ordered Ottawa to grant limited access to the material and gave a federal court judge the task of assessing what parts of the documents should be passed to Khadr's lawyers.

Last month, in his decision on what documents and videos could be released, Judge Richard Mosley said that the "practice described to the Canadian official" to prepare Khadr for the interview was "a breach of international human rights law respecting the treatment of detainees."

Canada "became implicated" in violating international human rights when the Foreign Affairs official learned about Khadr's treatment but decided to interview him anyway, the judge said.

Khadr lawyer Dennis Edney told CBCNews.ca Wednesday that the documents show that the "Canadian government lied to the Canadian people about what it knew about Omar Khadr's treatment."
