The fonds chiefly reflects Gordon Edwards' professional practice, both in consortium with various firms and as an individual practitioner, and also reflects his teaching career at McGill University and the Université de Montreal, however there are some files of a personal nature. Correspondence, lighting design proposals, and their accompanying documentation (such as architectural plans) are included. A majority of the files representing his professional projects contain the same types of documents: architectural plans, lighting fixture schedules, illuminance grids, and manufacturer's literature and brochures. In addition, there are some miscellaneous photographs both of professional and personal nature, negatives, and fabric samples.

The correspondence is both personal and business-related; most of it deals with his practice and various projects and proposals, but there is also correspondence relating to legal and banking matters. There are letters from Prime Minister Pierre Elliot Trudeau and Prime Minister Brian Mulroney. There is also correspondence from noted architect Moshe Safdie and Canadian War Museum architect Raymond Moriyama.

Plans include lighting designs for the Supreme Court of Canada, the Outremont Library, and the McCord Museum expansion project.
