A policy question was posed in 2001 to Canadian publics: should Canada proceed with clinical trials on xenotransplantation and if so, under what conditions? As part of its development of policy and regulations on this medical technology, Health Canada and the Canadian Public Health Association implemented a public consultation process that included a public opinion survey and deliberative citizen fora modeled along the citizens' jury. This study focuses on the citizen fora and describes an assessment of effectiveness based on an evaluation framework developed on the basis of concepts from constructive technology assessment and deliberative democracy.
