25 Cents Ontario; Camp 10

Camp 10 was one of the prisoner-of-war camps established in Canada during the Second World War under the provisions of the Geneva Convention, which required that POWs be paid for labor in scrip redeemable only within the camp economy. This prevented captured personnel from accumulating hard currency that could fund escape attempts. Ontario hosted several such facilities, and each issued its own denomination series independently.

The scrip was printed under federal authorization but administered locally, which accounts for the variation in quality and format across Canadian POW issues. Most were redeemed or destroyed at war's end, making survivors scarcer than their wartime production numbers would suggest.
