A seasoned litigator and leading authority on medical malpractice, Duncan is renowned for his deeply analytical approach to dissecting complex medical-legal issues. His passionate command of complex, multiparty civil litigation and institutional negligence has earned him the distinction of being one of Canada’s best trial lawyers. As a result, Duncan is consistently referred to by other top litigators.

Most recently, he played a key role in KB.v Guhle (2025 ABKB), one of the most significant medical malpractice trials in Canadian history, in which the Alberta Court of King’s Bench found a physician’s failure to meet the standard of care directly led to catastrophic injuries suffered by an 11-month-old patient.

For patients who have been injured due to medical malpractice or negligence, he is an invaluable advocate to have in their corner.
