Mirvish Productions is a Canadian theatre management and production company, based in Toronto, founded by David Mirvish in 1987. David's father, Ed Mirvish, had made headlines in 1963 when he purchased and saved from demolition Toronto's historic Royal Alexandra Theatre, one of the oldest and most famous legitimate theatres in North America. In 1987, David Mirvish assumed the responsibility for the family's theatrical interests and created Mirvish Productions for the purpose of producing original plays and musicals, employing Canadian talent, for the Royal Alexandra's stage, as well as co-producing with such regional Canadian theatres as the Stratford Festival, the Shaw Festival, the Manitoba Theatre Centre and the Citadel Theatre and bringing their works to Toronto. Mirvish Productions is, today, Canada's largest commercial theatre production company. Its offices are located at 284 King St. West - beside the Princess of Wales Theatre - in Toronto.
