@Chris in Ottawa -- the suit against the Federal government began before Harper was in power, and was as a direct result of actions taken by officials under the command of Chretien & Martin.

The SC rulings have not been ignored, and there are two outcomes:

1.  That Khadr's Canadian Charter rights were violated

2.  That the Federal government is not obliged to repatriate a Canadian citizen held by another country.  That ruling came down in 2010.

From there, it's a question of figuring out the compensation, if any.  The most similar case would be with British GITMO detainees, who received slightly less than $2M each.

Khadr was already in a US prison for almost 2 years before the first Charter breach

Contrary Arar, Milgaard and other innocents, Canada didn't put him there, so by definition his compensation should have been much, much less.
