Canada operated prison camps for 34,000 combatant German prisoners of war (POWs) during the Second World War. The POW camps at Lethbridge and Medicine Hat, Alberta, were the largest in North America. The attempts for escaping the prison were made by the prisoners during the second world war camps but all were captured again except for one prisoner. But the main reason the escapes were attempted was only because the prisoners and the guards wanted to do something to relieve themselves from their boredom. This is not a joke. Infact many world war 2 prisoners did not want to leave the prison after the war mainly because they received such nice treatment from the government and the guards in Canada that they refused to leave.
