In the post-Second World War period, the [[Soviet Union]] began developing a capable fleet of long-range [[bombers]] with the ability to deliver [[nuclear weapons]] across North America and Europe.<ref name = 'dow67'>Dow 1979, p.&nbsp;67.</ref> The main threat was principally from high-speed, high-altitude bombing runs launched from the Soviet Union travelling over the [[Arctic]] against military bases and built-up industrial centres in Canada and the United States.<ref name = 'dow60'>Dow 1979, p.&nbsp;60.</ref> To counter this threat, Western countries developed [[interceptor aircraft|interceptors]] that could engage and destroy these bombers before they reached their targets.<ref name= "Gunston p. 18">Gunston 1981, p.&nbsp;18.</ref><ref name = 'dow84-5'>Dow 1979, pp.&nbsp;84–85.</ref>

[[Avro Canada|A.&nbsp;V. Roe Canada Limited]] had been set up as a subsidiary of the [[Hawker Siddeley]] Group in 1945, initially handling repair and maintenance work for aircraft at the [[Malton, Ontario]], Airport, today known as [[Toronto Pearson International Airport]]. The next year the company began the design of Canada's first jet fighter for the Royal Canadian Air Force (RCAF), the [[Avro CF-100]] Canuck all-weather interceptor.<ref name = 'dow61-2'>Dow 1979, pp.&nbsp;61–62.</ref> The Canuck underwent a lengthy and troubled prototype stage before entering service seven years later in 1953.<ref name = 'dow70'>Dow 1979, p.&nbsp;70.</ref> Nevertheless, it went on to become one of the most enduring aircraft of its class, serving in a variety of roles until 1981.<ref name="Frontiers">Lombardi, Mike and Larry Merritt.

Recognizing that the delays that affected the development and deployment of the CF-100 could also affect its successor, and that the Soviets were working on newer jet-powered bombers that would render the CF-100 ineffective, the RCAF began looking for a supersonic, missile-armed successor for the Canuck even before it had entered service.<ref>Dow 1979, p.&nbsp;83.</ref> In March 1952, the RCAF's ''Final Report of the All-Weather Interceptor Requirements Team'' was submitted to Avro Canada.<ref name = 'dow84'/>
