It was established in the community of Argentia in what was then the Dominion of Newfoundland, which would later become the tenth Canadian province (see Newfoundland and Labrador). Established under the British-U.S. lend-lease program, the base was first occupied on January 25, 1941 following the expropriation of the flat headland formed by a small natural bay called Little Placentia Sound and the western end facing Placentia Bay by the Newfoundland government; over 400 families were displaced.
