During a visit to Kahnawake, Chief Norton showed us a Mohawk language maintenance program that was very important to him. It was a huge process. If I remember correctly, people needed to spend so much time relearning the Mohawk language that it was impossible for them to work full time while doing so.
Certainly resources are required to achieve something, and there's no budget for the act respecting Indigenous languages. I imagine that this uncertainty regarding funding isn't very reassuring.
