The organization was started by
James Roy, playwright
Anne Chislett and local newspaper editor
Keith Roulston in 1975. Its primary mandate was to produce and develop local Canadian plays. In 1975, few scripts that fit the festival's mandate were being written, so the festival's founders began to create new works and adapt the work of other Canadian playwrights. The first season included a play with an established reputation,
Agatha Christie's
The Mousetrap, but the popularity of the Canadian-written offering, Harry J. Boyle's
Mostly in Clover, encouraged the founders to focus on plays with local content. The Blyth Memorial Community Hall had an upstairs auditorium which had been little used for decades; this was refurbished to provide a venue for the festival. At that time, the Festival was the only summer theatre producing original Canadian plays. The Blyth Festival's archives are stored at the
University of Guelph. One of the festival's most financially successful plays was Beverley Cooper's
Innocence Lost: A Play About Stephen Truscott, staged in 2008. By 2014, the festival had premiered 120 original plays, including
Alice Munro's
How I Met My Husband, and the Governor General Award-winning
Quiet in the Land, by
Anne Chislett. ==Blyth Centre for the Arts==
