This theatre has been faithfully restored to the original 1920s Thomas Lamb design and opened in September 1989 with Andrew Lloyd Webber's "Phantom of the Opera". At that time is was called the Pantages Theatre but it has been rightfully renamed for the father of its current owners: The Ed Mirvish Theatre. Mr. Mirvish was the support behind the creation of the Princess of Wales Theatre.

Special acoustical concerns included the discrete integration of acoustical fabrics and the noise control design of HVAC equipment above and below the theatre. The restored building seats 2200 people and is one of the busiest theatres in Canada.

For years it out sold Toronto's Maple Leaf Gardens, English Canada's cathedral of ice hockey located just up the street. In Canada, selling more seats than hockey is quite an achievement!
