Just to clarify this a bit, when the Nunavut Land Claims Agreement was negotiated and signed, it was signed between the Government of Canada, Nunavut and Tunngavik, the organization that is now Nunavut Tunngavik Incorporated. It wouldn't necessarily be a request by NTI to ensure that languages are in Inuktitut because of it being enabling for other acts, including the Nunavut Act. The Nunavut Act, as enabling legislation, allowed for the Government of Nunavut to have authority over how elections would work within the territory of Nunavut, so that's more within the jurisdiction of the Government of Nunavut.
