Our history

During the 1970s, SickKids’ paediatric oncology unit was housed at Princess Margaret Hospital, while the haematology service was located within the Hospital. In 1980, on the recommendation of a task force, oncology was moved to SickKids, and the two services were combined into the Division of Haematology/Oncology in the following year.

In 1974, the Division Head, Dr. Peter McClure, performed the first-ever paediatric bone marrow transplant and SickKids soon became known as a leading centre for this procedure. Other significant achievements of the Division's haematology branch included the development of a comprehensive haemophilia program in 1983 and a sickle-cell anemia program in 1985. Haematology research flourished, with landmark studies of congenital bone marrow and hemoglobin disorders, and of the inherited and acquired paediatric bleeding disorders.

Initially, oncology was largely viewed as an add-on to the primary focus of the Division, namely the haematological diseases of childhood. The ensuing years saw a dramatic increase in our knowledge of the etiology and treatment of childhood malignancies, and the need for a separate oncology program within the Division became evident. Over the past two decades, growth in the combined division of paediatric haematology, oncology and haematopoietic stem cell (bone marrow) transplantation has been consolidated through the recruitment of new full-time faculty and the creation of multidisciplinary disease-specific sections/programs in both haematology and oncology. The division now boasts one endowed chair (The SickKids Women's Auxiliary Millennium Chair in Paediatric Haematology/Oncology) and funds to allow specialist training in thrombosis (The Baxter BioScience Endowed Fellowship in Paediatric Haemostasis), leukemia (the Markel Fellowship in Cancer Research), and paediatric oncology (Bank of Montreal Financial Group Oncology Fellowship and Scotiabank Clinician Scientist Training Fund).
