Lumby Productions Ltd began in 1961 as a audio recording service run by John Lumby (1930-2017) and his wife, Helen Hase Lumby (b. 1934). In 1965, it was incorporated as Lumby Productions Ltd. In 1985-1986 the assets of Lumby Productions were transferred to Size Small Productions Inc., a new company formed by the Lumbys in 1981. Lumby Productions Ltd. was fully dissolved in 1988 and was struck from the Saskatchewan Corporate Registry in 1989.

The company produced sound recordings, films, radio and television commercials and jingles, slide-tape presentations, print advertising, including promotional brochures, and photographic work, animation, and other public relations services. During the late 1960's and early 1970's the company did most of the film and news production for CBC Saskatchewan. It also produced films for provincial government departments and for private and crown corporations, and did marketing work for local Saskatoon performers such as the University of Saskatchewan's Greystone Singers and the Saskatoon Boys' Choir.
