No they weren't.Cheap! The CF-104s were second hand, and given cheap.
They were built by Canadair in Cartierville under a government purchase order. Orenda in Downsview built the OEL-7 that powered the aircraft. Most of the avionics were built by Canadian firms under license.
But I'm guessing that was a typo? And you meant CF-101?
The two batches of CF-101's we operated were never owned by Canada. Many of the "facts and ($) figures" of this arrangement remain classified, 35 years after we quit operating the type. The custody deal was based on something similar to the "Lend-lease" agreements from WWII. This was intertwined with arrangements with respect to the AIR-2 capability.
They remained USAF property until they were retired. Once this happened in 1984, the US "signed off" on a bunch of the airframes we had in our custody (with the obvious provision that they be "de-militarized") and these are the "gate guardians" that we now "own".
