The hotel underwent an extensive renovation program in 1972 and 1973 to modernize its image. Called the Royal York Revelation, the program was overseen by the architects Webb Zerafa Menkes Housden (who also designed the Royal Bank plaza next to the hotel). The renovation cut a hole in the main-floor lobby for a spiral staircase, covered the marble pillars in the lobby with wood panelling, hung modern wall lamps and a chandelier and replaced rugs with carpet. From 1988 until 1993, the Royal York underwent a $100-million restoration.
