From Wikipedia:
"In October 1942, between 1,500 and 4,000 prisoners revolted against the POW guards after they were shackled as retribution as part of the escalation of Germany's new Commando Order."
"Approximately 100 requisitioned from another base in Kingston arrived, and together stormed the mess hall using only ice hockey sticks, so the two sides remained evenly matched. After several hours of brawling, the Canadians brought high pressure water hoses and soaked the cabin thoroughly until the prisoners agreed to come out peacefully."
How Canadian can you get?
