Canada's most famous spy was William Stephenson, the man called Intrepid. The Winnipeg-born businessman supplied the British with important information on the growing German war machine in the 1930s and went on to head the office of British Security Coordination. It was Stephenson who created a top-secret spy school on the shores of Lake Ontario known only as Camp X. Agents came from all over the western world to be trained in the latest techniques and technologies of the spymasters.
