It would be hard to answer your question. I believe there are immersion schools in Yukon. As for the Northwest Territories and Nunavut, I will have to look for the answer.
You mentioned iPads, for example, tablets and other electronic devices. Your question is eminently philosophical: how do we ensure that young people will always continue speaking French, English or both languages? I believe that question goes to the solidity of the community and the framework we offer young people.
One thing is certain: this is a very complex matter for us in the north, as I mentioned earlier. In Nunavut, for example, they speak English, French and Inuktitut, and, if I'm not mistaken, Inuinnaqtun is the fourth official language. Not only are young people living in the community with which they identify—francophones living in a francophone community—but they are also surrounded by a population that mainly speaks Inuktitut. That also changes the situation. Personally, I believe that young people are still speaking the language and opening up to other languages because they come from established communities whose continued existence is guaranteed.
