Richard A. Waite, British-born Buffalo architect, was given the contract to design the building. This was after as a member of the selection committee he had decided that the Gothic design (the other most recognizable medieval architectural style), proposed by Darling and Curry was unsuitable. The architectural style Richardsonian Romanesque was developed by Henry Hobson Richardson , and it was perfected in New England. When they were designing the civic structures in Toronto they favoured this Richardsonian Romanesque style. E.J. Lennox designed Old City Hall in the Richardsonian Romanesque style, and R.A. Waite chose the style for these, the Ontario Parliament Buildings.
