Series consists of accounts and correspondence of the Ontario Cancer Institute; minutes of the Board of Trustees and the Building Committee; lecture notes, speeches and memorandums; reprinted articles; grant applications and correspondence regarding Dr. Ash's research on adrenalectomy; minutes and reports from the Ontario Cancer Treatment & Research Foundation; correspondence by Dr. Gordon E. Richards, President of the Ontario Institute of Radiotherapy; cancer statistics and annual reports from the Ontario Institute of Radiotherapy; and minutes of the National Cancer Institute. Records reflect the varied administrative, teaching and research activities undertaken by Dr. Ash while Director of the Ontario Cancer Institute and contain files relating to his previous and concurrent positions as radiologist under Dr. Gordon E. Richards at Toronto General Hospital(1940-1949), senior radiologist at the Toronto General Hospital (from 1949), Professor of Radiotherapy at the University of Toronto and Radiotherapist in Chief to The Toronto General Hospital. Records do not include files from the offices of subsequent holders of this position. The statistics files include cancer statistics from 1924 to 1956. Files 2.50-2.57 relate to the Ontario Cancer Treatment and Research Foundation. Files 2.84-2.108 are the files of the President of the Ontario Institute of Radiotherapy which were created at the Toronto General Hospital and probably accumulated by Dr. Ash in 1949 when he was appointed Senior Radiologist at the Toronto General Hospital. Dr. Ash probably brought these files with him to the Ontario Cancer Institute when he became Director. Files have been arranged as close as possible to the order in which they were found, although the original order had probably been tampered with prior to their transfer to the Archives.
Gaps exist in the records between 1926 and 1934, 1966 and 1969, and 1969 and 1975.
