The city of Barrie, Ontario, and the Canadian medical community are in mourning following the death of Dr. Sean Cleary, MD, a renowned Professor of Surgery at the University of Toronto. Widely regarded as one of Canada’s foremost surgical experts, Dr. Cleary’s passing marks the end of a career that significantly advanced the field of surgery and inspired generations of physicians.
Dr. Cleary specialized in hepatobiliary and pancreatic surgery, tackling some of the most challenging and high-risk cases with remarkable skill and precision. He practiced at leading Toronto hospitals, where his expertise in treating complex liver, pancreas, and bile duct diseases made him a trusted figure among patients and peers alike. His ability to balance clinical excellence with genuine compassion set him apart as both a healer and a mentor.
Beyond his surgical practice, Dr. Cleary was deeply committed to academic medicine. As a Professor at the University of Toronto’s Department of Surgery, he played a pivotal role in training residents, developing innovative surgical techniques, and contributing to groundbreaking research. His lectures were known for blending rigorous scientific knowledge with practical insights, and many of his students credit him as a major influence in their careers.
Tributes have poured in from across the country, with colleagues remembering him as a leader who led by example—always prioritizing patient safety, medical ethics, and continuous learning. “Sean had an incredible ability to connect with people, whether it was in the operating room, the classroom, or the community,” one fellow surgeon shared.
Dr. Cleary’s impact was also felt beyond the hospital walls. He actively participated in medical outreach programs and was a frequent speaker at international surgical conferences, where his expertise was sought after by peers from around the world. In Barrie, friends recall his warmth, generosity, and devotion to family life.
