The availability of interpreters is pretty good. Not the Cree Nation Government, but the Cree regional James Bay government, is a regional government structure where half of the membership is Cree and the other half is the non-indigenous communities in the riding. That's the regional government in northern Quebec. In their proceedings and deliberations, there's simultaneous Cree, French, and English translation. The services are there and are easily accessible. In fact, I suggest you communicate with that regional government to talk about the service and how it works.
