Two Avrocar prototypes were constructed and completed a series of wind tunnel tests at NASA Ames in California and a 75 hour flying program at the Malton home of Avro Canada. The results of the testing revealed a stability problem and degraded performance due to turbo-rotor tolerances. Before modifications could be achieved, funding ran out with the final flight test program completed in March 1961. With the problems that the contractor was facing in the wake of the cancellation of its premier fighter program, the Avro Arrow by the Canadian government, Avro was unable to continue the project. The Avrocar had been the last aviation program of Avro Canada. The parent company. A. V. Roe Canada which had been in throes of disintegration for years ceased to exist on April 30, 1962 .

Both Avrocars are still intact, and survive in U.S. museums. The U.S. Army Transportation Museum at Fort Eustis, Virginia received the second Avrocar, the "flying" prototype, 59-4975 from the U.S. Army Aviation Materials Laboratories at Fort Eustis, Virginia in 1979. The first Avrocar, S/N #58-7055, the unmanned test rig and wind tunnel test vehicle marked as AV-7055 was never flown. It was shipped to the NASA Ames Research Center wind tunnel at Moffett Field, California in 1960. After wind tunnel testing, it remained for years in storage at the NASA facility before being donated to the National Air and Space Museum in 1966. Today AV-7055 is stored in Building 22 of the NASM Paul E. Garber storage and restoration Facility, in Silver Hills, Maryland.

As the result of his work in vertical takeoff systems, John Frost was invited to become a fellow of the Canadian Aeronautics and Space Institute after he presented the W. Rupert Turnbull seventh lecture on May 25, 1961. The citation noted that Frost had discovered and patented the air cushion effect that had been evident in his work on flying saucers and that U.S. Patent #3124323 "Aircraft Propulsion and Control" was one of a series of patents to became known as the "Frost patents".
