Argo is a fictional film. It was the Canadian Embassy staff who harboured the American diplomats and hatched the plot for their escape. The Canadian parliament approved issuing fake passports for these people and the CIA botched the issuance of Visas, which Canada corrected. The car chase at the end did not happen. Just a Hollywoodized action film, pure fiction.
