The need for Indigenous rights to be recognized and for reconciliation to occur is becoming increasingly engrained in the fabric of Canada. From the perspective of Indigenous peoples in Canada, reconciliation is seen as a process of decolonization. With the launch of the Oceans Protection Plan in 2016, the narrative of Indigenous engagement was brought directly to the topic of shipping governance. But the question remains: how to achieve reconciliation in concrete and tangible ways through policies and governance procedures? Importantly, reconciliation is not a discrete state or a destination, but a continuous process.In Canada, area-based approaches are becoming more common in the regulation of marine affairs, including shipping. The increasing prevalence of area-based, ecosystem-based approaches is resulting in the development and application of decision support systems (DSSs) that are designed to process, visualize, integrate, and communicate information. While the significance of such DSS cannot be overestimated, a less discussed fact is that the knowledge of coastal communities is remarkably difficult to represent unless it is adapted to the language and requirements of these tools and systems. In practice, this results in decreasing the value of observational, “local” knowledge while increasing the significance of quantifiable “scientific” observations or measurements. This chapter proposes that the ways of treating local knowledge in area-based management can facilitate or hinder processes of reconciliation in the context of ocean governance.
