"Documents obtained by Global News in September indicated that the concept was briefly looked at by the government and dismissed.
CBC then reported MacKenzie’s comments that the federal government was too fast to write off the proposal to build a made-in-Canada military aircraft, which he says would be cheaper, faster and more efficient than the F-35.

Their plan was to redesign the Avro Arrow as an alternative to the F-35."
