The Whonnock Memorial Hall Society was incorporated on December 15, 1975. On December 1, 1981, the name of the society was changed by special resolution to Whonnock Community Association (WCA). The Association carried out a historical project in 1985, prompted by the 1980 celebration of the 90th anniversary of the Whonnock school, an occasion which brought many former residents of Whonnock together. The intention of the WCA was to produce a booklet on the history of the Whonnock community with an emphasis on the establishment of postal service in the area. Funding for two summer student research positions was provided by Challenge '85, British Columbia/Canada Summer Employment Program. The target date for the booklet was the 100th anniversary celebration in 1990. Although the manuscript was not completed nor the book published, the research data and materials were saved and preserved by the WCA.

Anthony Samuel Taulbut was a native of Fareham, Hampshire England who settled in Mission with his wife Rozina and two children, Walter and Amy in 1908. He established a real estate and insurance business and soon became actively involved in the community, serving as the municipal and school district assessor (1917-1939), School Board secretary (1920-1946), and Mission correspondent to the Vancouver Province (1922-1949).

An avid collector with a keen interest in history, Anthony established a museum and archives in part of his house, serving as Mission’s first de facto curator and archivist. As his enthusiasm spread throughout the community, many people from the area contributed local artifacts and archival items to his collection. In later years, began work on a history of Mission, which was never completed due to his untimely death on August 16th, 1949.

The Pacific Cooperative Union was established in 1932 to help farmers process and sell their fruit. The cooperative's members, many of Japanese descent, came from throughout the Fraser Valley. The Cooperative established its main plant in Mission, B.C., first processing berries and later vegetables and jam. The Cooperative ceased operations in 1973 and was formally dissolved in 1984.

Nicomen Island Women's Institute was established in 1947 and served Nicomen Island in the Fraser River east of Mission.

The Mission Memorial Centre Society was incorporated in 1973 to promote and coordinate social services in the District of Mission. The Society operated the Mission Memorial Centre, previously the Mission Memorial Hospital building. The Society was dissolved in 1989.

In 1920, a group of women banded together and formed the “Memorial Hospital Auxiliary” to support, enhance and promote health care in our community through volunteering and fundraising.

Through their efforts and innovative services and programs, the Auxiliary has played an integral role in the establishment, construction, and furnishing of Mission’s hospitals (est. 1920, 1925, and 1965).

Among their most outstanding fundraising efforts were “May Days” which they inaugurated in 1921 to provide revenue for the hospital and which went on to become a Mission institution.

Over the decades, the Auxiliary has also developed programs and services for patients, staff and the community, including: a hospital gift shop, a thrift store, ambulatory day care, and assisting long term care facilities.
