Unfortunately the disinformation about this story never ends. Omar Khadr did not "go out of his way to leave Canada and join the enemy". He was taken out of the country by his father when he was a 9 or 10 year old child. He did not "renounce his Canadian citizenship". 

A soldier of an invading army was killed in combat. That is a tragedy for his family but it is not, and never has been, a "crime".
