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.

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.

The records of the Montreal-Ottawa Conference of the United Church are arranged in the following series:

1. Denominational records prior to Union, 1824-1925
   Records of each of the three parent denominations follow the same general pattern. There are minutes, usually printed, of the national executive body, and original minutes of the local unit corresponding to the geographical boundaries of the present Conference. Papers of associations at this level generally include the files of Sabbath School associations, ministerial associations, missionary societies, and theological colleges. A number of interdenominational clergy and mission groups are also represented; while a special series of correspondence, minutes, and conference reports covers the debates concerning union, 1906-1925. The Methodist materials begin in 1824, and the Presbyterian in 1841, and the Congregational in 1842.

2. Conference records, 1925-
   Minutes of the Conference, and of the Conference-based Women's Missionary Society, Women's Union and United Church Women, are extant from the time of Union. The Montreal Presbytery maintains a record of proceedings, and supports a number of groups and associations (Minister's Wives Association, young peoples' groups, camps, missionary societies, United Church Women) whose work is documented by minutes, financial records and, occasionally, correspondence files. Also included are records of the Joint Theological Colleges of McGill University and of the United Theological College, 1912-1948.

3. Local Churches, 1832-
   Many local churches retain their historical records, including civil registers. The Archives' holdings include records of approximately 75 individual congregations in the Montréal and Québec-Sherbrooke Presbyteries, consisting of minutes of governing bodies, communion rolls, minutes of organizations, accounts, annual reports, and occasionally photographs and architectural drawings. The most substantial and significant records are those of the Erskine and American (from 1832), including records of Canada Education and Home Missionary Society, 1833-1848, St James (from 1820), Zion Congregational (from 1832), and Odelltown (from 1829) congregations.

4. Missionary Work in French Canada, 1848-1861, 1876-1969
   The importance to the United Church and its parent denominations of mission work in French Canada is documented by minutes of the French Canadian Missionary Society (1848-1861), and papers, including sermons, notebooks and correspondence of the French Evangelical Church of Canada (1876-1969).

5. Papers of individuals, 1822-1925
   Papers of individuals include the correspondence, essays and sermons, 1870-1917, of Calvin E. Amaron; the Bieler Family; J. Armitage Ewing (largely concerning the controversies surrounding Union in 1925); William Mair, sermons, 1827-1855; Richard Robinson, diaries, personal records, sermon outlines, 1857-1912; Henry Wilkes, 1822-1878, and others.
