Self-regulation has long been at the core of sociological understandings of what it means to be a "profession." However, the historical processes resulting in the formation of self-regulating professions have not been well understood. In Regulating Professions, Tracey L. Adams explores the emergence of self-regulating professions in British Columbia, Ontario, Quebec, and Nova Scotia from Confederation to 1940. Adams’s in-depth research reveals the backstory of those occupations deemed worthy to regulate, such as medicine, law, dentistry, and land surveying, and how they were regulated. Adams evaluates sociological explanations for professionalization and its regulation by analysing their applicability to the Canadian experience and especially the role played by the state. By considering the role of all those involved in creating the professional landscape in Canada, Adams provides a clear picture of the process and illuminates how important this has been in building Canadian institutions and society.
