Canadian SIGINT in the 1945-1998 period

Some notes I wrote about the birth and post-war history of the Communications Branch of the National Research Council (CBNRC)/Communications Security Establishment (CSE) for a website that I once had:

Chronology of Canada's Postwar SIGINT Activities

(Kudos to the Internet Archive for preserving the site.)

Note that the chronology extends only to 1998, so none of the major changes the agency has undergone since 9/11 are included.

Two other points worth mentioning:

- We now know that the UKUSA Agreement (originally called the BRUSA Agreement) was signed on 5 March 1946, not in 1947 or 1948.

- We also now know that the CANUSA Agreement between Canada and the U.S. was reached in 1949.
