So Canadian soldiers are angry that the torture of detainees is overshadowing all the good they are doing over there. We would be too. Torture is like that.
Here is modest proposal: if you are upset at handing over detainees that may be tortured, stop doing that. You are fully in your rights and obligated by international law to do so.
Its your choice boys. Torture is like hard-drugs, it tends to corrupt the moral fabric and overshadow all else.
