The major record of the McGill Chapter's early years is a register containing members' signatures, 1911-1969, and minutes from 1912 to 1932; a second minute book covers the period 1960-1969. Approximately two-thirds of the papers are secretary's files from 1961 to 1978 containing membership lists, correspondence concerning prospective members, circular letters announcing meetings, and correspondence with the headquarters of AOA. There are also receipts for initiation fees from 1954 to 1969.

The fonds contains ledgers, legal documents, permits, one scrapbook, and photographs.

The fond consists of artifacts, bound volumes, photographs, and records from the Montreal Medico-Chirurgical Society. Included are correspondence, minute books, reports, monthly bulletins, a register of members, memorabilia, and albums of clippings and photographs.

Files 46-62 in particular include a significant amount of minutes, newsletters, and event information. Correspondence, reports, publications, press clippings and photographs comprise a smaller portion of the files. Secretarial and annual reports, activities, and minutes from the Rheumatology section are included. The society's gavel is part of this fonds.
