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

Context paragraphs:
Peter Cope: Peter Roland Cope (7 December 1921 – 4 April 2005) was the last surviving test pilot from the Avro Arrow program.

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.

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.

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.

The Arrow: The Arrow is a four-hour miniseries produced for CBC Television in 1996, starring Dan Aykroyd as Crawford Gordon, experienced wartime production leader after the World War II and president of A. V. Roe Canada during its attempt to produce the Avro Arrow supersonic jet interceptor.  The film also stars Michael Ironside and Sara Botsford.  The mini-series is noted as having the highest viewership ever for a CBC program.

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.

Haley Industries: Haley Industries is a Canadian company which manufactures lightweight metal castings for use in aerospace applications.  It was a prime contributor to the Avro Arrow aircraft project.

Velvet Glove: The Velvet Glove was a short-range semi-active radar homing air-to-air missile designed by CARDE (today DRDC Valcartier) and produced by Canadair starting in 1953.  131 Velvet Gloves had been completed when the program was terminated in 1956, officially because of concerns about its ability to be launched at supersonic speeds from the Avro Arrow then under design, but also from the design being overtaken by developments in the United States.

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.

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.
