The fonds consists of three accruals of correspondence, minute books, financial statements, news releases, circulars, contact lists and issues of Hamilton Area Tools for Peace and Tools for Peace News.

The collection consists of seven statements of expulsion from the Yonge Street Monthly Meetings mostly held at Pickering. One of the statements makes specific reference to Elias Hicks. More than one of the statements makes reference to participation in the Rebellion of 1837 which violated the known Christian Testimony against war. There is also an extract from the Yonge Street Monthly Meeting held on 12 December 1839 and a one-leaf untitled, unsigned manuscript of religious writing.

The collection consists of approximately 200 pages of love letters exchanged between Katina Paxinou and Sir Sydney Waterlow between 1938 and 1939. There are 45 letters written by Paxinou, 30 by Waterlow. The letters are written in French with occasional sections in Greek and English.

Katherine Clarke has dubbed her archives “The Peace House Papers”. Digital copies of the originals and documents from 2009-10 have been placed by her into three folders: book one, “Finding Causes”, consisting of biographical information and letters to her parents between September 1963 and June 1964; book two, “Touring Cuba with 45 Canadians in the summer of 1964 … In the 5th year of La Revolución Cubana”, consisting of photographs of her time in Cuba (including photos of Fidel Castro speaking to a large crowd and playing baseball), photographs of “Harry” and other soldiers (a soldier in Castro’s army, pre-1959, i.e. before the revolution photographs), and her account (entitled “Sugar Daddy”); book three, letters to her parents between September 1964 and March 1965. Originals of most of these materials are also extant in the Clarke fonds.
