Question: Which government canceled the aircraft known as the Avro Arrow?

full_context: Document 1: Owen Maynard: Owen Eugene Maynard (October 27, 1924 – July 15, 2000) was a Canadian engineer who contributed to the design of the Canadian CF-105 Avro Arrow jet interceptor; and NASA's Apollo Lunar Module (LM). Maynard was a member of the group of 32 Canadian and British engineers from Avro Canada who joined NASA when the Arrow was cancelled in 1959. Maynard worked on Project Mercury until 1960 and then moved to the Apollo program. Maynard won a U.S. patent (US3300162) in 1967 for a space station design.
Document 2: Avro Canada: Avro Canada was a Canadian aircraft manufacturing company. It started in 1945 as an aircraft plant and within thirteen years became the third-largest company in Canada, one of the largest 100 companies in the world, and directly employing over 50,000. Avro Canada was best known for the highly advanced CF-105 Arrow, but through growth and acquisition, it rapidly become a major, integrated company that had diverse holdings.
Document 3: Chris Gainor: Chris Gainor is a historian of technology specializing in space exploration and aeronautics. He has written four books on the history of space exploration and on the Avro Canada CF-105 Arrow, a jet interceptor aircraft canceled by the Canadian government in 1959.
Document 4: Lockheed SR-71 Blackbird: The Lockheed SR-71 "Blackbird" is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed with a reduced radar cross-section.
Document 5: Marc Garneau: Joseph Jean-Pierre Marc Garneau, {'1': ", '2': ", '3': ", '4': "} (born February 23, 1949) is a Canadian politician and the Minister of Transport in the Government of Canada. He is a retired military officer, former astronaut, and engineer; Garneau was the first Canadian in space taking part in three flights aboard NASA Space shuttles in 1984, 1996 and 2000. Garneau was the president of the Canadian Space Agency from 2001 to 2006, and in 2003 was installed as the ninth Chancellor of Carleton University in Ottawa.
Document 6: Avro Canada C102 Jetliner: The Avro C102 Jetliner was a Canadian prototype medium-range turbojet-powered jet airliner built by Avro Canada in 1949. It was beaten to the air by only 13 days by the de Havilland Comet, thereby becoming the second jet airliner in the world. The name "Jetliner" was chosen as a shortening of the term "jet airliner", a term which is still in popular usage in Canada and the United States. The aircraft was considered suitable for busy routes along the US eastern seaboard and garnered intense interest, notably from Howard Hughes who even offered to start production under license. However continued delays in Avro's all-weather interceptor project, the Avro CF-100, led to an order to stop working on the project in 1951, with the prototype Jetliner later cut up for scrap.
Document 7: Lockheed F-104 Starfighter: The Lockheed F-104 Starfighter is a single-engine, supersonic interceptor aircraft which later became widely used as an attack aircraft. It was originally developed by Lockheed for the United States Air Force (USAF), but became widely used by US Allies around the world, and produced by several other NATO nations. One of the Century Series of fighter aircraft, it was operated by the air forces of more than a dozen nations from 1958 to 2004. Its design team was led by Kelly Johnson, who contributed to the development of the Lockheed P-38 Lightning, Lockheed U-2, Lockheed SR-71 Blackbird and other Lockheed aircraft.
Document 8: Orenda Iroquois: The Orenda PS.13 Iroquois was an advanced turbojet engine designed for military use. It was developed by the Canadian aircraft engine manufacturer Orenda Engines, a part of the Avro Canada group. Intended for the CF-105 Arrow interceptor, development was cancelled, along with the Arrow, in 1959.
Document 9: Avro Canada CF-105 Arrow: The Avro Canada CF-105 Arrow, often known simply as the Avro Arrow, was a delta-winged interceptor aircraft designed and built by Avro Canada. The Arrow is considered to have been an advanced technical and aerodynamic achievement for the Canadian aviation industry. The CF-105 (Mark 2) held the promise of near-Mach 2 speeds at altitudes of 50000 feet and was intended to serve as the Royal Canadian Air Force's (RCAF) primary interceptor in the 1960s and beyond.
Document 10: John Hodge (engineer): John Dennis Hodge (born 1929) is a British-born aerospace engineer. He worked for the CF-105 Avro Arrow jet interceptor project in Canada. When it was cancelled in 1959, he became a member of NASA's Space Task Group, which later became the Johnson Space Center. During his NASA career, he worked as a flight director and planner. When he returned to NASA in the 1980s, he worked as a manager on the Space Station Freedom project, which later became the International Space Station. He also served as an administrator at the United States Department of Transportation.
Document 11: Chris Hadfield: Chris Austin Hadfield {'1': ", '2': ", '3': ", '4': "} (born 29 August 1959) is a retired Canadian astronaut who was the first Canadian to walk in space. An engineer and former Royal Canadian Air Force fighter pilot, Hadfield has flown two space shuttle missions and served as commander of the International Space Station.
Document 12: Orion abort modes: NASA's newest spacecraft, the Orion Multi-Purpose Crew Vehicle (MPCV), will be the first American spacecraft since Project Apollo to use an escape system in the event of a launch abort, something its predecessor, the Space Shuttle, had for only its first four orbital test flights in 1981-1982. Like the Apollo Command-Service Module (CSM), the Orion CEV will use the Launch escape system (LES), a solid-fueled tractor rocket that will be able to pull the Orion crew module away from a malfunctioning Space Launch System (SLS) rocket during the initial launch phase. Based on the launch escape system found on the Soviet/Russian Soyuz spacecraft, the LAS, designed and manufactured by ATK for the Orion CEV, will be larger than the Soyuz version and will have more thrust than the Atlas 109-D booster that carried astronaut John Glenn into orbit in 1962.
Document 13: Hawker Hunter: The Hawker Hunter is a transonic British jet-powered fighter aircraft that was developed by Hawker Aircraft for the Royal Air Force (RAF) during the late 1940s and early 1950s. It was designed to take advantage of the newly developed Rolls-Royce Avon turbojet engine and the swept wing, and was the first jet-powered aircraft produced by Hawker to be procured by the RAF. On 7 September 1953, the modified first prototype broke the world air speed record for aircraft, achieving a speed of 727.63 mph .
Document 14: Jim Chamberlin: James A. Chamberlin (May 23, 1915 – March 8, 1981) was a Canadian aerodynamicist who contributed to the design of the Canadian Avro Arrow, NASA's Gemini spacecraft and the Apollo program. In addition to his pioneering air and space efforts, he is often cited as an example of Canadian brain drain to the U.S. In the early 1960s, he was one of the key people that proposed and moved that Lunar Orbit Rendezvous (LOR) was the best option for landing a crew on the Moon, the method eventually used on Apollo lunar landing missions. He left NASA in 1970 and worked for McDonnell Douglas, in their Houston offices, until his death in 1981.
Document 15: Lockheed Martin F-22 Raptor: The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
