The Canadian aerospace industry was murdered by diefenbaker. Killing the most advanced fighter in the world was not enough, not only was it scrapped but the Americans who were willing to buy the technology, were refused and the idiot was so anti-nuclear he told them no, and the Americans just hired the talent and got it for nothing.
Bombardier did the only thing they could do, given the state of the US integrity run by a crazy man, and being faced with a clown to help fight it.
The only other choice was to kill the aerospace industry again
