The Canadian Oncology Societies was founded in 1976 when several oncologists joined together with a common interest, through the efforts of Dr. Carl Reise, a surgical oncologist from Winnipeg.
In 1974, Dr. Reise took the initiative to the Canadian Cancer Society. This initiative was then supported by Dr. Anthony Miller and after two meetings in 1975 (Royal College, January 1975 and NCIC, March 1975), an agreement was reached to form the Canadian Oncology Societies. The first annual meeting of the Canadian Oncology Societies was held on January 26, 1977 in Toronto with 66 founding members in attendance. Dr. Reise was the founding president and Dr. Anthony Miller of Toronto, the first Secretary/Treasurer.
Over its 30 year history, the mandate of the Canadian Oncology Societies has evolved, particularly in view of the development of several new oncological specialties associations such as the Canadian Association of Medical Oncologists and the Canadian Society of Surgical Oncologists to name a few.
With the various discipline-related mandates of the oncological subspecialties, the Canadian Oncology Societies has become a federation of oncological societies with a common voice in Oncology. The membership of the Canadian Oncology Societies includes the Canadian Association of Medical Oncologists (CAMO), the Canadian Hematology Society (CHS), the Canadian Society of Surgical Oncology (CSSO), the Society of Gynecologic Oncologists of Canada (GOC), the Canadian Association of Nursing in Oncology (CANO) and the Canadian Uro-Oncology Group(CUOG). In a retreat of the board of directors held in July 1994, the goals and objectives of the society were reviewed and the following issues were agreed upon and subsequently implemented by the membership.
