Soldiers Used as Guinea Pigs for Chemical Warfare Tests
200 Canadian soldiers volunteered to have mustard gas sprayed on their arms that had been coated with "barrier creams," concoctions the British Army was trying to develop to protect troops in the field from mustard gas attacks ... Canada conducted tests that were similar to those at Porton Down. The Canadian tests also used volunteer soldiers and were performed at a laboratory in Ottawa and at CFB Suffield, Alta. The soldiers were paid one dollar a day to be guinea pigs for the chemical warfare agent tests.
