In 2005, Wiens, then aged 79, became the first Western Canadian architect to be given a career retrospective, in a major travelling exhibition celebrating forty years of his work from 1955 to 1995, curated by Trevor Boddy and organized by the Mendel Art Gallery in Saskatoon, titled "Telling Details: The Architecture of Clifford Wiens", displaying over 170 examples of work including architectural models, drawings and photographs.
