The contributions of Canadian community psychologists to ethics, theory, methodology, research, and practise are highlighted in this article. Important debates about ethical issues in psychological research and practise have been advanced by Canadian community psychologists. Canadian community psychologists have also introduced theoretical perspectives (e.g., cognitive community psychology) that have provided an impetus for research and practise, and they have broadened the focus of research in community settings with contributions to participatory action research, program evaluation, and qualitative methods. A variety of substantive contributions have been made to the research literature, especially in the areas of community mental health, prevention, and social inclusion. Finally, Canadian community psychologists have contributed to practise in terms of policy, programs, and social interventions. The article concludes with a discussion of future potential areas of contribution for Canadian community psychology.
