In response to the loss and issues encountered, Avro Canada dismissed several members of the design team and established a special working group to rectify a major structural design error identified. To address the latter, a straightforward modification was developed that could be easily retrofitted into the pre-production aircraft. While both prototypes had been powered by Avon engines, the subsequent pre-production and production series aircraft used the locally developed Orenda powerplant instead, the first of which flying during June 1951. As a result of delays encountered in the development of the Orenda, its selection unavoidably impacted the CF-100 programme's timetable as well. Dissatisfied with the pace of development, Cabinet Minister C. D. Howe informed Avro to suspend work on all other projects and focus its efforts on completing the CF-100.
