‘The Crowsnest’ was the monthly magazine of the Canadian Navy from November 1948 until June 1965 when, as a result of the Canadian Forces Unification Act, it was replaced by a magazine intended to serve all Canada's Armed Forces.
The purpose of ‘The Crowsnest’ was:
to provide unclassified material of news, information and, to some extent, entertainment value as a broad contribution to the internal morale of the Royal Canadian Navy and Royal Canadian Navy (Reserve), and to maintain interest in the Naval Service amongst former naval personnel . . .
from the final edition of ‘The Crowsnest’ Magazine citing a letter written in August 1948.
