A bit of background, as it was told to me by the officer in the picture: The young officer was a CELE (Air) captain working at Trenton ~ he had an undistinguished military career but a rather more successful one as an engineer with TeleSat ... he just happened to be near the flight line on the day the ad agency was shooting the piece and he was dragooned into it. I'm no sure if they did any photoshopping or if, just as likely, a foreign aircraft was in Trenton for some reason.
Further to Old Sweat's comments: the ad actually did some good, in its own way. It crystalized some senior officers' thinking about what had gone so dreadfully wrong with what should be, actually, a fairly simple business. Some of our leaders began to fight back ... it was, and it remains a loooooong uphill struggle and there has been much backsliding on the way, but I think we you the CF saw the one error of its ways. Of course, for every admiral and general who saw that management was destroying both leadership and the military ethos there was another general or admiral who thought exactly the opposite. We were seeing, in our own senior ranks, what Evelyn Waugh described in the Sword of Honour series of novels ( in Officers and Gentleman, I think, but it may have been Men at Arms or Unconditional Surrender) as military men being, in reality, just "heavily armed civilians."
Several colossally bad decisions ~ including e.g. the formation of Air Command ~ date from that period.
