History

The Acacias has historic value through its associations with early owners of the residence, especially the Windeat sisters (Emma Sarah and Louisa Helen) who built the house circa 1911. Emma Windeat, likely the most notable member of the family, was one of the first female artists to become a member of the Royal Canadian Academy of Arts. The next owner of the property, Willis Norman Millar, was an assistant professor of Forestry at the University of Toronto and a published author of several books on forestry management practices. The house is also associated with well-known local architect, George Nepean Molesworth. Molesworth (1885-1958) was a prolific architect who designed many buildings (commercial, institutional and residential) in Toronto and Oakville.

Heritage attributes

The Acacias has significant physical value as a 2-1/2 storey home with Arts and Crafts inspired details. Known for the acacia trees that surround the residence, the house was designed to fit into the landscape surroundings and despite changes in the lot size since its construction circa 1911, the connection between the residence and its surroundings is still significant.
