Michael Ordon


Associate Scientist, Li Ka Shing Knowledge Institute


Dr. Michael Ordon is a Staff Urologist at St. Michael’s Hospital and an Associate Scientist in Li Ka Shing Knowledge Institute. Following his residency training at the University of Toronto, he completed a two-year fellowship at St. Michael’s Hospital specializing in kidney stones, minimally invasive urologic surgery and renal transplantation. During this time, he also completed a Master of Science in Clinical Epidemiology and Health Care Research through the Institute of Health Policy Management and Evaluation, at the University of Toronto. He also completed a second fellowship at the University of California Irvine focusing on image-guided ablation for small kidney tumours. His clinical practice focuses on the surgical management of complex kidney stones, renal transplantation, laparoscopic urology, and robotic-assisted surgery, as well as image guided cryoablation of small renal tumours. His primary research interest is in health services research and he holds an appointment as an Adjunct Scientist at the Institute for Clinical Evaluative Sciences (ICES). In particular, his research focuses on the epidemiology and treatment of kidney stone disease and outcomes research for renal transplantation.
