Arthur Erickson, Canadian architect and urban planner, designed Roy Thomson Hall (born 1924)

Arthur Charles Erickson was a Canadian architect and urban planner. He studied at the University of British Columbia and, in 1950, received his B.Arch. (Honours) from McGill University. He is known as Canada's most influential architect and was the only Canadian architect to win the American Institute of Architects AIA Gold Medal. When told of Erickson's award, Philip Johnson said, "Arthur Erickson is by far the greatest architect in Canada, and he may be the greatest on this continent."

Roy Thomson Hall is a concert hall in Toronto, Ontario, Canada. Located downtown in the city's entertainment district, it is home to the Toronto Symphony Orchestra, the Toronto Mendelssohn Choir, and the esports team Toronto Defiant. Opened in 1982, its circular architectural design exhibits a sloping and curvilinear glass exterior. It was designed by Canadian architects Arthur Erickson and Mathers and Haldenby. Itzhak Perlman acted as a special advisor to the architects on accessibility needs for disabled performers and guests.
