We actually use indigenous people, with tribes making up that group of people. I believe there’s more, but the ones I know off hand are Métis, Inuit, and First Nations. So we too use that term, but it isn’t an overall blanket for indigenous people. I also feel I butchered that explanation, but wanted to explain First Nations is a tribe, not a general descriptor.
Also, land acknowledgments are part of morning announcements at all schools in the area I’m in, just outside Toronto. While it’s good, and it’s a great step to reconciliation, I feel (know) the kids don’t always listen to it. I had a conversation about it with kids just this past week, referring to what the bands were known as in our area. They don’t quite get that connection in the elementary level.
