Based on extensive research including visits to most health centres and facilities in Nunavut, Gregory Marchildon and Renée Torgerson have produced a comprehensive review of healthcare in Canada's newest territory. Nunavut: A Health System Profile provides an in-depth examination of population health and healthcare in the territory. Little more than a decade old, Nunavut has a population that consists of thirty-thousand residents living in twenty-five widely dispersed communities. No roads connect the territory's isolated populations and nearly all supplies and equipment are transported by air. Consequently, health service delivery in Nunavut is the costliest in Canada and its operation encounters challenges more extreme than those faced elsewhere. Marchildon and Torgerson consider the historical and demographic context of healthcare in Nunavut, as well as the finances, governance, infrastructure, workforce, and program provisions that define the system. Due to a high incidence of suicide and the psychological upheaval associated with rapid societal change, the authors call particular attention to the treatment of mental health and addictions. Filling a gap in our understanding of one of Canada's most important and expensive social policies, Nunavut: A Health System Profile provides the first comprehensive review of the health system in Nunavut and the distinct health issues the territory faces. Gregory P. Marchildon is professor in the Johnson-Shoyama Graduate School of Public Policy with campuses at the University of Regina and the University of Saskatchewan. Renée Torgerson is a health care researcher residing in Alberta.
