The Squaw Harbor Cannery was located on Unga Island, one of the islands that composes the Aleutian Islands in Alaska. It was one of the canneries acquired by Pacific American Fisheries (PAF) in 1917 when demand for salmon increased during World War I.

Henry Loofs, who worked for the Alitak Cannery, maintained a 1941 logbook of fishing activities around Olga Bay, near Kodiak Island. Alitak Cannery was also purchased by PAF in 1935. The Petersburg Cannery was located on Mitkof Island south of Juneau and was also purchased in 1935 by PAF.
