Marion Gruner

Marion Gruner has been working as a documentary producer, director, writer and researcher since 2002. She began her career at a small but mighty global education centre, producing documentaries that tackle global issues not normally covered in the classroom, and spent several years travelling to communities around the world covering stories about fair trade, food security and health. In 2003 and 2004 she wrote and filmed Smoke Damage in Nigeria and Senegal, a documentary on the international tobacco industry and its efforts to expand production and marketing efforts in the global south. 

In 2004, Marion joined Toronto’s Cogent/Benger Productions as a production manager, and shortly afterward began developing, researching and writing several new projects. In 2008, she co-directed and wrote Pharma Sutra for CTV’s W5, an investigative documentary following three Big Pharma products as they race to cash in on a five billion dollar “female Viagra” market. 

While developing Pharma Sutra, Marion returned to Africa to film A House That Fits, about the work of a Canadian architect who believes the solution to the affordable housing problem lies in one, smart design. She continued directing her own projects while developing and managing several productions for Cogent/Benger. 

In 2011, Marion produced, wrote and co-directed The Autism Enigma with Christopher Sumpton, for CBC’s The Nature of Things. It’s the story of an international group of scientists examining the gut’s amazingly diverse, and powerful microbial ecosystem for clues to the baffling rise in autism. The Autism Enigma’s Canadian premiere was the highest rated episode for The Nature of Things’ 2011 season.

Working with Infield Fly Productions, Marion developed Against All Odds: The RCAF Flyers for Rogers SportsNet. In 2017, the film was nominated for a Canadian Screen Award for Best Sports Program. Marion story produced the Olympic Channel series Green Road,  about passionate Olympians from around the world, who have committed themselves to the environmental movement. She wrote and directed the episode on Bronze-medalist windsurfer and ocean protector, Bryony Shaw.

Working again with Infield Fly, Marion helped research and develop The Power of Poo for The Nature of Things, which aired in 2018. Most recently she was Associate Producer for Infield Fly’s Clydesdale: Saving the Greatest Horse, which premiered on CBC’s Documentary Channel in November 2020.

Marion also works with communities, educators, corporations and arts organizations, helping them tell their important stories through writing, documentary and podcast production. She has worked on several projects for the University of Guelph, the University of Waterloo, Re•Vision Centre for Art and Social Justice, Shared Value Solutions, and Storytellers of Canada-Conteurs du Canada.

Mine was made for Ed Video’s Play Proposition project. The challenge was to create a portrait of a collector or collection, and complete it in an hour or so. My daughter was the first collector that came to mind.
