Roy Thomson Hall is home to the Toronto Symphony Orchestra, the Toronto Mendelssohn Choir, and The Toronto International Film Festival. The hall, built in 1982, closed for extensive enhancements during the year of 2002 and opened with a Gala Inauguration in September of that same year. The original designer of Roy Thompson Hall was Arthur Erickson/Mathers and Haldenby. Acousticians were Bolt, Beranek and Newman Inc.

The Hall includes the 2812-seat auditorium, a small rehearsal hall, musician support areas, function rooms, music library, change rooms, administrative offices and on-site parking. One of the hall's unique features is a concert pipe organ designed and built by Gabriel Kney.

The current enhancements include the addition of substantial wood planking which shrinks and reshapes the upper volume of the hall. Wood finishes have been applied to the flooring, balcony walls and soffits, and all of the significant acoustical surfaces. A further improvement was the installation of a two-piece adjustable canopy system over the entire stage area. Motorized acoustical banners made of sound-absorptive materials have also been placed at the face of the wooden bulkheads; they are designed to descend from, and retract into, storage pockets in the attic. Seating has been redesigned to include two fore and aft aisles on the main floor orchestra level, as well as the addition of a number of side boxes.

Artec provided Design and Planning services covering Auditorium Design, Facility Planning, Specialized Performance Equipment Systems Design and Noise & Vibration Control consulting for this enhancement project. The principal architect is Thomas Payne of Toronto's Kuwabara, Payne, McKenna, Blumberg group (KPMB).
