The 4th Toronto International Film Festival (TIFF) took place in Toronto, Ontario, Canada between September 6 and September 15, 1979. Due to overcrowding in the prior year, the Gala presentations were moved from the 700-seat Towne Cinema to the 1,600-seat Elgin Theatre. The People's Choice Award was awarded to Best Boy by Ira Wohl, which later won Oscar for Best Documentary Feature.
