As far as the francophone population is concerned, the vast majority of them live in Iqaluit. So there is a school there. Since Iqaluit is no more than five kilometres long, that would be easy to organize.
There are also francophones in other Nunavut communities, such as Pangnirtung and Kimmirut, for instance, but these are tiny places with only a few people. During the last general assembly a few weeks ago, there was discussion about a project with the French school board of Nunavut to provide services online, to provide Internet base training, including for young people, as a complement to the education which francophone parents would like to maintain, even though they live in a community which is 99.9% anglophone.
