I do not know the full story on this (nor does my boss, who was around in 1959).
In 1959 the biggest thing was fighter aircraft to defend the US (and Canada) from huge Russian bombers flying over Canada to bomb the United States. Obviously, Canada was involved. They built fighter aircraft too. But in 1959, United States said their own fighters would be the best. This destroyed the Canadian program!
Canada was under financial problems so they closed their program. Many workers ended up going to other countries (US, France, etc.).
Turns out that maybe Canada had better ideas. Their “entry” may have been superior to even the F-35 which is superior to the 2017 F-35 fighter.
But Canada dumped many aircraft; Dumped into Lake Ontario or Lake Erie.
Now the big thing is to go into Lake Erie or Lake Ontario.
Hard to follow, so MAY BE yet another “Internet Hoax”
