Christopher Witiw




Christopher Witiw entered the neurosurgery residency program at the University of Toronto after completing his MD at the University of Manitoba in 2012. During his residency he completed a MS degree with a focus on Health Economics at The University of Chicago after receiving an award from the Canadian Institutes of Health Research. His thesis on the value of surgery for Degenerative Cervical Myelopathy was awarded the prestigious Outstanding Paper Award from the North American Spine Society in 2016. He has received numerous other awards including the Shafie S. Fazel Outstanding Resident Surgeon and Investigator Award from the University of Toronto Department of Surgery and the Alan R. Hudson Neurosurgery Resident Teaching Award from the University of Toronto Division of Neurosurgery. After obtaining his FRCSC in Neurosurgery in 2018, Chris undertook a subspecialty fellowship in Complex and Minimally Invasive Spine Surgery at Rush University Medical Center in Chicago. Chris returns to Toronto as a Surgeon Investigator at St. Michael’s Hospital where his clinical work is directed toward treating the full spectrum of spinal disorders. He has a specific interest in minimally invasive approaches to spinal conditions. Chris’ research work is centered on Health Economics and Health Services pertinent to spinal pathology and he is especially interested in ‘big data’ analytics as a means to optimize efficiency and quality of spine surgery.
