More than two decades ago, David Barker published a landmark paper describing the fetal origins of adult disease hypothesis, which posited that suboptimal conditions during pregnancy 'program' the fetus for the development of chronic diseases in adulthood. 1 The conceptual underpinnings of the fetal programming hypothesis were built on a series of epidemiological studies linking indices of adversity in early life with cardiovascular mortality in later life. In the ensuing decade, this concept stimulated a great deal of interest and work from research groups all around the world, and this global effort culminated in the first World Congress on the Fetal Origins of Adult Disease, convened in 2001 in Mumbai, India. In 2004, following the second World Congress held in Brighton, UK, the society adopted the title of 'Developmental Origins of Health and Disease' (DOHaD), to 'recognize the broader scope of developmental cues, extending from the oocyte to the infant and beyond, and the concepts that early life environments have widespread consequences for later health.' 2 The first meeting of the DOHaD Society was held in Toronto in 2005, highlighting Canada as a prominent entity in the field. In 2016, DOHaD Canada became a recognized chapter of the International DOHaD Society. The Inaugural Meeting for DOHaD Canada, held in Montebello, Québec in 2017, was a resounding success, attracting leading investigators, clinicians and traineesa testament to Canada's engagement in the field. Canada continues to uphold its commitment to DOHaD-related research; with a membership of almost 200 investigators and trainees, DOHaD Canada will host its third meeting in Mont-Tremblant, Québec in February of 2019. The meeting will focus on the country's research strengths: epigenetics and omics mechanisms underlying DOHaD, vulnerable populations, and solution-oriented research and policy. DOHaD Canada's mission is to be a globally connected network focused on creating, translating and communicating the latest knowledge on early development to improve the immediate and long-term health of Canadians, and to promote maternal-child health and well-being on a global platform. The Society engages in social, biological, clinical and economic research focusing on: (i) how environmental factors during the early life period (preconception, childhood and adolescence) interact with development to place individuals on trajectories that impact lifelong health, learning and social functioning; and (ii) development of strategies that prevent or reverse negative lifecourse outcomes, promoting health and wellness for all Canadians. Within its broad mandate, DOHaD Canada has made a concerted effort to address the unique health needs borne of its diverse populations, storied cultural heritage, expansive geography and varied climates. As a country, Canada ranks among the highest in international indices of civil liberties, quality of life, education and government transparency. Canadians take immense pride in the nation's commitment to multilateralism and intern...
