The purpose of this paper is to illustrate, through a Canadian case study, the bureaucratic support and obstacles for community participation in health promotion. The paper begins with a brief history of the development of a participatory health promotion programme in Canada. The role of bureaucracies on participation of communities is highlighted. Secondly, the paper describes how a variety of bureaucratic factors affected grassroots community participation efforts of local projects in one province. Finally, discussion focuses on how community participation is constrained in a bureau-cratically mediated activity such as health promotion.
