The Toronto Central Regional Cancer Program is led by a team including two Ontario Health (Cancer Care Ontario) Regional Vice Presidents and physicians who have taken on the role of Regional Clinical Leads in a particular area of cancer care. Regional Clinical Leads help ensure partner hospitals are aligned with the goals of Ontario Health (Cancer Care Ontario), promote collaboration within the region, and work toward measurable improvements in the quality and organization of cancer services within their region.

A steering committee provides further support and guidance in developing and implementing strategies to improve the delivery and quality of cancer services in the region.
