Casson often spent summers in Glen Williams, which he used as a base to paint local scenes. The village itself is the subject of Casson's 1938 oil on canvas, "Street in Glen Williams", a leafy, autumnal portrait of a quiet road in the hamlet, which sold at auction in Toronto on June 1, 2010 for a record $542,800, including buyer's premium, the highest such valuation ever accorded a Casson canvas. Casson, who joined the Group of Seven in 1926, "recorded small towns in every season," Canadian art critic and historian Paul Duval wrote in 1980, "and Street in Glen Williams is unquestionably his key autumn portrayal." Other paintings of Casson's time in and around Glen Williams include "Country Road - Glen Williams", "Village Street October", and "Farmhouse near Glen Williams 1938", now in the Firestone Collection of Canadian Art at The Ottawa Art Gallery. Today Glen Williams is a predominantly residential community that provides housing for residents employed in other areas. Glen Williams is home to many visual artists, contains a collection of artist's studios and is a major draw to the area. Glen Williams has a compact community core that includes commercial uses, a restaurant and bakery, the community centre (Town Hall) and other recreational and community functions.
