I'll provide a short response.
Essentially the Nunavut Impact Review Board is responsible for conducting the environmental assessment. What the CNSC provides is the scientific and technical support for all aspects of the environmental assessment, and we play the role of coordinating the scientific support to the NIRB with other federal government agencies like Environment Canada and DFO. So that's the role we play.
Should the project be accepted by the NIRB, then there are some water boards in Nunavut that need to give permits, and the CNSC would also need to provide a licence.
