Built in 1927 and modelled after Malahide Castle, near Dublin, Ireland, the courthouse features a stone foundation housing the cell blocks, squared mortar-covered brick walls to give a stone-like appearance, octagonal towers, a polygonal bay, tall lancet windows, secondary square windows and distinctive crenelations. With Gothic detailing, the courthouse displays a classical form with a central pavilion and two side wings in the form of prominent octagonal towers at each corner. Interior features high beamed ceilings, detailed wood panelled walls and parquet flooring. The jail facilities were added in 1942. As an easement property of the Ontario Heritage Trust, the building is still used by city council. All rooms are available as part of an event centre plan including the second floor council chambers and wardens office, CAO boardroom, library and council room, basement historic jail, and Middlesex Room which can seat 300. Parking available on site.
