Can't forget about the Avro Arrow. http://en.wikipedia.org/wiki/CF-105_Arrow

It was an interceptor developed in the 1950s that was 20 years ahead of its time.

Unfortunately, the Conservatives scrapped the program in the 1959s along with the prototypes because it was "too expensive."

Most scientists went to the US. So basically the entire modern US airforce and space program were based on Canadian innovations.
