History

The Edmund N. Killer House is one of the earliest examples of development in the Brantwood Survey and is a good representative example of the type of family homes built in this part of Oakville for the prosperous upper middle class. The house was built by Edmund N. Killer and later lived in by Marion Banting, the first wife of Sir Frederick Grant Banting, the Nobel laureate best known for leading hte team of scientists who discovered the hormone insulin. Information post-designation revealed the construction date as 1916.

Heritage attributes

The house is a 2 1/2 storey stucco-clad vernacular house built with Arts and Crafts and Georgian design elements. The structure was built using hollow clay bricks, an unusual and rare building material for the Oakville area at the time.
