History

The Dr. John A. Johnstone House has historical value because of its direct associations with Dr. John A. Johnstone, a well-known veterinary surgeon who practiced in Halton County for over 50 years. Dr. Johnstone was also the veterinary inspector for Halton County for 30 years and was the first Deputy Reeve of Trafalgar Township. John and his wife Catherine raised six children in the subject house. The property also has historical associations with the former village of Trafalgar, also known as Post’s Corners and Postville.

Heritage attributes

The Dr. John A. Johnstone House is a representative example of a late 19th century Queen Anne style residence. Constructed in the 1890s, the house has an asymmetrical and eclectic design, typical of the style. Built on a lakestone foundation, the house is clad in horizontal wood siding and contains a number of design elements reflective of the Queen Anne style, including: the first storey bump-out with a rounded window; segmentally-arched windows throughout; the projecting second storey underlined by a bracketed frieze; decorative half-cove (or a close approximation of) shingles in the third storey gable; exposed eaves; and matching sets of decorative corbels.
