Bull Collection publisher C. V. Charters, Everett Briggs, Alex McKinney and other citizens moved to create a historical society, focused on life in Peel County from the late 18th century to the 1930s.

Regular meetings began in 1962, and included an address by "Mr. Colucci", designer of the Black Creek Pioneer Village in north Toronto.

With aid of the Women's Institutes of Snelgrove and Cheltenham, an art exhibition was held in an old school house, on the 3rd Line, in the west half of Chinguacousy.

Meant to raise funds for the creation of a museum and art gallery, it featured artworks by prominent local artists, and items from the Bull Collection.

In 1963, the organization became an affiliate of the Ontario Historical Society oncemore, and displayed during the fall at the International Ploughing Match, held in Caledon by Colonel Conn Smythe.

The official opening took place November 17, 1968, featuring professional designed exhibits and displays, "a very fine variation from the more frequently encountered county museums", according to a 1973 text on the Society.

In the Region of Peel Museum, visitors can travel from early Aboriginal settlements through the Jet Age, all within the walls of an historic Jail building.

Beyond these municipal documents, the archives collects documentary material related to the history of Peel, and the individuals and groups that have helped in developing the community.

Since opening in 1968, the art gallery has exhibited local, national, and international artists, both contemporary and historical from their permanent collection.

The selection includes works by early movements, such as Les Automatistes and Painters Eleven, and contemporary figures in non-objective painting, such as David Urban and Ric Evans.

Artists mentioned in publicity for the gallery include John Anderson, Caroline Armington, Frank Armington, John Armstrong, Carl Beam, George Broomfield, Alex Cameron, Chuck Close, Tom Dean, Mary Dignam, Leonard J. Hutchinson, Tom LaPierre, Doris McCarthy, David Milne, Robert Motherwell, Will Ogilvie, Stephanie Rayner, Jim Reid, Jack Shadbolt, Michael Snow, Stanley Spencer, Tom Stone, Andy Warhol, and Joyce Weiland.

Seniors programs, which go out to old-age facilities, feature broader history and art-related topics, not necessarily focused around Peel.

The Peel Heritage Complex collects a wide variety of objects including: 19th and early 20th century artifacts from everyday tools and gadgets to wedding dresses, archaeological artifacts, historic and contemporary works of art, including paintings, drawings and sculpture, and archival documents such as photographs, government records, and maps.

In the Art Gallery of Peel approximately eight exhibitions are featured annually, showcasing artists of Regional, provincial and national stature.

Each spring, the Gallery's Annual Juried Show, the longest running adjudicated exhibition in the area, attracts artists from throughout Peel and Southern Ontario.

Visitors to the Heritage Complex will also be treated to interactive displays, hands-on activities, and learning opportunities throughout the building.
