Abstract Despite advances in impact assessment (IA) practice in Arctic regions, persistent challenges remain. This article examines how baseline information needs and associated uncertainties are presented and understood in the regulatory context of IA. The focus is on marine-related information needs in the Nunavut IA process. The method used a document review of operational IA reports and focus groups with the Nunavut Impact Review Board – the agency responsible for IA in the territory. The results show that information challenges are largely linked to the availability, suitability and accessibility of data; while challenges to addressing information needs are related to broad capacity constraints, as well as responsibility, and cooperation among parties to the process. Similar to other settings, in Nunavut, there is a need to develop better guidance for parties regarding information uncertainties in IA and how such may be addressed. To help address information needs, there is also a need to clarify the roles, responsibilities and expectations of all parties (e.g. Inuit organisations, proponent, government and communities), as well as improving coordination and advancing collaboration, while also addressing capacity constraints.
