To Nanoose, a serious response: 

Mahar Arar's situation is different, but still comparable.  Mahar was innocent and deserving, no doubt about it, but two differences go the other way: 

1. Arar was only 16 when Canadian officials interrogated him while he was being tortured, and turned over results to the Americans. Arar was 32.

2. Arar was held for 1 year. Khadr was in Guantanamo for 10. The actions of our officials contributed to that, and to his 'guilty plea'. 

It took a little over 4 years from the start of Arar's mistreatment for him to receive compensation and an apology - not speedy.  However, in Khadr's case, it has taken 14 years (13 since he started his lawsuit).  That's not exactly a "panic" to settle.

The Harper government could undoubtedly have made a settlement 10 years ago to return him to Canada and pay perhaps a hundred thousand dollars in damages.  Instead they ran up millions in losing court costs.
