Designed by Diamond and Schmitt Architects and constructed by Jeviso Construction Corporation, renovations to the station's platform were completed in April 2008 to evoke exhibits in the Royal Ontario Museum. Supporting columns have been remade to resemble the ancient EgyptiandeityOsiris, as well as Toltec warriors, Doric columns found in the Parthenon, China's Forbidden Citycolumns, and First Nations house posts. This renovation purged Museum station's original tile scheme from the platform level. Walls were reclad with mauve aluminum plate panels by Ontario Panelization of London, ON. They incorporated painted 1/4" fire rated Lexan into the "MUSEUM", with a historical heiroglyphic inscription, from the ROM. However, a small section of the original tiling and 'museum' lettering can be found at the very south end of the southbound platform, though the tiles have been painted a more neutral colour to blend in with the mauve paneling, along with the lettering, now painted black.
