Umm, no.  All governments were engaged in violating Khadr's rights, the Harper government by leaving him in Guantanamo.  And not incidentally, while Chretien and Martin had to deal with Bush - Harper had Obama who WANTED our nation to repatriate our citizen.

The unanimous 2010 SC ruling  stated Khadr's rights were being violated on an ongoing basis - right up tho the time then that he was repatriated. And while a lower court ruling stipulated that the government (then Harper) should repatriate Khadr, the Supreme Court was more careful - but also indicated the would step in on repatriation if the federal government did not act.
