The collection consists of material accumulated by the Coquitlam Heritage Society over the course of its existence. The collection includes the following: records related to Fraser Mills (later the Canadian Western Lumber Company, then Crown Zellerbach) including ledger books, journals, statements, photographs, and various other records; records related to the lumber industry in Coquitlam; photographs of historic Coquitlam; glass plate negatives by W.J. Moore and Richard Broadridge; material related to the administration of the Coquitlam Heritage Society itself; and miscellaneous records related to Coquitlam's history

The fonds consists of two scrapbooks and one wooden name plate. The scrapbooks were put together by Dr. Thomas G. Caunt, who worked at Crease Clinic and the Provincial Mental Hospital, Essondale, starting in 1935. He created the scrapbooks for his son and daughter as a record of his employment.

The scrapbooks detail significant moments of Caunt's medical career and personal life during 1934–1968, as well as various events at Essondale Hospital, including the installation of the BC Tel telephone exchange. A significant portion of the scrapbook documents the trips Caunt took in 1949-1950 to move geriatric patients to the new Homes for the Aged in Vernon (Dellview) and Terrace (Skeenaview).
