In 1985 Robert Turner retired from teaching, and he is Professor Emeritus of Music at the University of Manitoba. His second opera, House of Shadows, was completed in 1986, and many of his most significant orchestral works were written in the years following this retirement: Shades of Autumn (1987), Third Symphony (1990), Manitoba Memoir (1991), House of Shadows (1994), and River of Time (1994). During the 1990 season, in celebration of Turner's 70th birthday, the Winnipeg Symphony Orchestra performed five of his major orchestral works under the direction of Bramwell Tovey.
