Has anyone filmed at Riverview before? Riverview would be the perfect set for my film, does anyone know if they would be willing to let me film in one of their rooms or something, and where to get permission? Thanks!

Believe it or not, this has come up on DVInfo before. Try doing a search.

Also, this is the link you are looking for. Thank Google.

Two of BCBC's main sites for film and TV production are Riverview Hospital and the Burnaby Women's Correctional Centre, properties located in the Lower Mainland area. (http://www.bcbc.bc.ca/Doing_Business_With_Us/Filming/)
