Ottawa had its own top-secret code-breaking establishment
In 1942, David Hayne, a recent University of Toronto graduate, was undergoing artillery training at Camp Niagara in Ontario when he received two mysterious letters that changed the course of his life and helped place Canada in the forefront of intelligence gathering.
The first was from a professor of French who asked Hayne if he would fill an opening at the National Research Council (NRC). There was no indication of what the work involved, only that it was connected with the war and that the letter writer found it absorbing. The young grad concluded that the job related to the French language, his passion. Still, he dispatched a cautious reply, saying he expected to begin his military career almost immediately.
