Not all canneries focused on salmon. The Ceepeecee Cannery is an example of a plant that focused on pilchards even after the addition of a salmon canning line.
Ceepeecee Cannery was built in Esperanza Inlet in Nootka Sound as a pilchard reduction plant. The plant was owned by Canadian Packing Corporation, a subsidiary of the California Packing Corporation. Pilchards remained their main industry even after Nelson Brothers Fisheries added a canning line in 1934 when they purchased the plant.
Pilchard stocks collapsed in 1945 due to over-fishing, so operations at Ceepeecee switched to herring reduction. The plant was destroyed by fire in the late 1950s.
