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.
