Canadian Caper
The "Canadian Caper" was the joint covert rescue by the Government of Canada and the US Central Intelligence Agency (CIA) of six American diplomats who had evaded capture during the seizure of the United States embassy in Tehran, Iran, on November 4, 1979, after the Iranian Revolution, when Islamist students took most of the American embassy personnel hostage, demanding the return of the US-backed Shah for trial. After the diplomats had been sheltered by the British mission and Canadian diplomatic personnel, the Canadian and United States governments worked on a strategy to gain their escape through subterfuge and use of Canadian passports.
