The "Canadian Caper" was the joint covert rescue by the Canadian government and the 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.
Americans were grateful for Canadian aid in sheltering and rescuing American diplomats during the Iran hostage crisis of 1980.
The Iran hostage crisis was a diplomatic standoff between Iran and the United States. Fifty-three American diplomats and citizens were held hostage after a group of militarized Iranian college students belonging to the Muslim Student Followers of the Imam's Line, who supported the Iranian Revolution, including Hossein Dehghan, Mohammad Ali Jafari and Mohammad Bagheri, took over the U.S. Embassy in Tehran and took them as hostages. The hostages were held for 444 days, from November 4, 1979 to their release on January 20, 1981. The crisis is considered a pivotal episode in the history of Iran–United States relations.

Anticipating the takeover of the embassy, the Americans tried to destroy classified documents in a furnace. The furnace malfunctioned and the staff was forced to use cheap paper shredders. Skilled carpet weavers were later employed to reconstruct the documents.

Barry Rosen, the embassy's press attaché, was among the hostages. The man on the right holding the briefcase is alleged by some former hostages to be future President Mahmoud Ahmadinejad, although he, Iran's government, and the CIA deny this.
