Completed in 1886 this structure was designed under the direction of Thomas Fuller, Chief Architect of the Department of Public Works from 1881 to 1896. The Brockville Post Office shows the sensitivity often displayed by Fuller and his staff. The basic design with a double entrance and a steep roof was adapted to many small post offices across Canada, but varied here by the presence of superb stonework and a central pedimented gable with flanking gables. Each post office was unique but collectively they shared a resemblance that came to symbolize the federal presence throughout Canada.
