The Wheelhouse Theatre is a 290-seat proscenium theatre located at Earl Marriott Secondary School. It is the largest performing arts theatre on the Semiahmoo Peninsula. The Wheelhouse's primary usage is as a classroom and training facility for students pursuing theatre, and its secondary usage is as a well-equipped and affordable rental house to the community. It is managed by the school and its Theatre Department Head (as of June 2007, Rick Harmon), as well as by the Wheelhouse Theatre Society, a collaboration of community volunteers mandated to raise funds for, and contribute necessary equipment purchases to, the theatre.
