There's a lot of work ahead in that regard. There will need to be clear and open lines of communication between the federal office involved and all of these other entities it needs to engage with, in terms of provincial and indigenous governments. There's a challenging task ahead for the commissioner. Choose the commissioner wisely. Get the very best person you can in that role, someone who's going to have good lines of communication.
That said, in a federation, it's not easy or appropriate to force provincial governments to take steps, but I would hope all would be enthusiastic to participate in such an important project as the revitalization of indigenous languages.
