The fonds consists of professional papers, architectural and silver artifact photographs, drawings, teaching materials, research files on historical buildings in Québec, and heraldry designs for Boy Scouts. The bulk of the fonds consists of professional papers and three-dimensional objects (1889-1949). These have been arranged into twelve categories based on function: notes by Traquair for architecture curriculum courses; personal items of Traquair; signed notes of Gordon Antoine Neilson; signed notes of Marius Barbeau; Boy Scouts' flag design and correspondence; drawer list of drawings of French-Canadian architecture as arranged by Traquair; source clippings/publications; student sketchbooks; historic notes on individual places; publications of Traquair; publications by others working in the field or allied fields; line blocks. 14 original drawings in the fonds date from 1901-1921 and include watercolours and drawings of Egypt and India as well as details and sketches of churches in England and Italy. There are also approximately 550 measured drawings of historic buildings in Montréal, Québec City and elsewhere in the province made by Traquair and his students. Approximately 5 m of photographs portray landscapes, historical buildings, furnishings, and rural people at work in Québec; some copies of historical prints and photographs are also included. The historical architecture of Québec is also the subject of 1 m of plastic negatives, and a further 40 cm shows old Québec silverware.

Included is the constitution, by-laws, and minute books covering 1922-1940. Approximately one half of this material consists of membership cards recording the name, rank, degrees, and publications of members from 1920 until ca 1970. There are also membership lists for various periods including the founding members and lecture lists, ca 1930s. The secretary's files, covering the period 1963-1969, contain files on dues collected, expenditures, membership (nominations, transfers, correspondence with members), the national convention, and chapter meetings. Financial transactions from 1939 to 1946 are recorded in the treasurer's account book.

The fonds contains the majority of the drawings and papers of Montreal architect and landscape architect John Schreiber, who was a professor in the School of Architecture at McGill from 1953 to 1987. These documents constitute a rich treasure of original design work, expressed in draughtsmanship of great virtuosity. John Schreiber’s work is an example of the contribution to Canadian architecture and landscape architecture of a generation of Europeans who, leaving that war-shattered continent in the late forties and fifties, found an appreciative and fertile ground for their talents and ambitions in Canada. The two hundred and thirty four projects represented in the Schreiber fonds span half a century of work and are documented in more than four thousand plans and drawings, hundreds of photographs and close to six linear metres of textual files.

The archive consists of drawings for planning and architectural projects, preparatory notes and visual documentation for Schoenauer's books and articles, as well as course notes, photographs, small sketches and research files on the typology of Canadian housing. The archive reflects the breadth and depth of Schoenauer's involvement with architecture, housing and planning in Canada; his profound commitment to teaching; and his labours as an author of a fundamental, and far-ranging text on housing as a sine qua non of civilized existence.
