This article examines the state of community-based management and participatory governance in Canada as it applies to integrated coastal and ocean management (ICOM). The article analyzes the barriers confronting participatory governance, the success stories and the lessons learned, as well as presenting recommendations for moving forward. There is compelling evidence that participatory governance is crucial for contending with complex problems of managing for multiple values and outcomes to achieve ecological sustainability and economic development. Canada’s Oceans Act, and federal oceans policy provide a strong basis for the participatory governance and community based management of coastal and large ocean resources. The implementation of the Oceans Act and oceans policy has resulted in some steps toward participatory governance but has not adequately provided the mechanisms for a strong role for communities in integrated coastal and ocean management (ICOM). In order to strengthen and develop community participation in ICOM, nine initiatives are recommended: (1) shifting paradigms, (2) overcoming ‘turf protection,’ (3) ensuring compatibility of goals, (4) ensuring sufficiency of information, (5) dealing with internal community stratification, (6) creating cross-scale linkages, (7) creating a participatory policy environment, (8) building community capacity, and (9)monitoring and assessment of local-level initiatives. The authors say that capacity-building is necessary both to overcome the barriers to collaboration and to strengthen existing participatory efforts. In overcoming these barriers and in creating a collaborative environment, capacity-building is required for all participants, be they with government, industry, scientific institutions, or communities. It is suggested that these capacity building efforts will be more effective if these different groups can combine their efforts by coming together in learning communities for ICOM.
