The Michif in Saskatchewan is what we're calling “northern Michif”, and it's very heavily based on Cree. The one that's critically endangered is what we call “heritage Michif”, which is the original language from which the other Michifs evolved.
I envy the settlements for having that close community, with not only the proximity to sustain their language but also an infrastructure that enabled them to provide it. Also, once you have a majority situation in the school, it's a lot easier to leverage the support for Michif language inclusion all across Saskatchewan. It's a Métis community, so it's taught every day in the school, and the teachers are Michif speakers as well. Again, that's northern Michif, and it's primarily Cree.
