Dr. Sinclair subsequently pursued neurosurgical training at the University of Alberta and obtained his Royal College Specialist Certificate in Neurosurgery in 1995. He then joined the neurosurgical group at Dalhousie University where he focused on pediatric and trauma neurosurgery. In 1997 Dr. Sinclair was afforded an opportunity for adventure as ship’s crew and part-time physician aboard the Barque Picton Castle on its maiden 19-month circumnavigation of the globe. Upon his return in 1999 he obtained his CSPQ (Neurochirurgie) and joined McGill’s Faculty of Medicine in the Division of Neurosurgery at The Neuro.
