Princess of Wales Theatre, Theatre in the Entertainment District, Toronto, Canada

The Princess of Wales Theatre is a heritage-designated theatre in Toronto's Entertainment District with three seating levels providing a total capacity of 2000 seats. The building features contemporary architectural details and flexible spaces designed for various types of performances.

Construction began on August 6, 1991, with Peter Smith of the Toronto firm Lett-Smith as project architect. Ed and David Mirvish built the theatre to stage large-scale musicals for long runs, and it opened on May 26, 1993, with a Canadian production of Miss Saigon. In September 2012 Mirvish announced a Frank Gehry-designed complex that would have demolished it; a revised plan in May 2014 spared the building.

David Mirvish commissioned Frank Stella's murals, 10,000 square feet in all, covering the auditorium ceiling dome, the proscenium arch, the walls of lounges and lobbies on all four levels, and the outside back wall of the fly tower. Stella also designed the decorative fronts of the boxes and balconies and the end-caps of each seating row.

The theatre sits on King Street West in the Entertainment District, one block west of its sister venue, the Royal Alexandra. Elevators reach all three seating levels, and the whole building is barrier-free, so wheelchair users can reach orchestra, dress circle and balcony. The stage floor was rebuilt for The Lord of the Rings with three interlocking turntables and 17 independent elevators.

The stage includes three interlocking turntables and seventeen independent elevators that enable complex technical productions. These engineering systems allow for swift stage changes and give directors the freedom to explore experimental staging.
