Bower Featherstone was a Canadian civil servant who was convicted of espionage in 1966.
[2] A promising young officer in the RCMP Security Service, Gilles G. Brunet, played a significant role in his conviction, work for which he won a promotion.
Decades later western intelligence learned that Brunet, the young officer who won promotion for his work in convicting Featherstone, had also been a mole.
The main document he was convicted of handing over to the Soviets was a confidential chart of two shipwrecks southeast of Newfoundland.
Featherstone was the first individual to be convicted under the Official Secrets Act since the trials that followed the defection of Igor Gouzenko in the late 1940s.
