Haha, no worries, I expected as much. I respect your willingness to learn.

Tribes are different and yes also by geographic locations but each contain villages aka reserves. Several tribes can occupy similar territory. For Example, where I live now, you have Cree, Blackfoot...so on, each is a Nation and share the land. The Language and culture can be different yet similar because of proximity (province). Some fundamentals remain the same but the creation story according to the land's features will vary between nations but with one common origin of Turtle Island. The further across the country, it completely changes. The culture in the mountain is different than the culture of the plains or in the east and the culture of the North will be completely different just like central Canada since most of the culture evolves around the land and it's resources and each face different challenges.

There are many many different First Nations, too many to list them all. I'm from the eastern tribes. Genetics Maliseet (Madawaska) but spent my teen years/early adulthood with Mi'kmaq , also my second parents (childhood bff's family) were from the same reserve but left and lived next door growing up, actually there was a small handful of us . Moved out west and been learning more about the western and northern tribes since my city is the gateway to the north(well the Northwest Territories & Nunavut portion of it.

It's some weird autonomy on reserves but with many challenges via antiquated treaties, lots of grey areas around that. They do retain some land and hunting fishing rights along with dual citizenship with the us with a "status card" ( a form of ID associated with the treaty rather than a federal ID but still is a federal ID but you have to live on reserve or be full Native, it's complicated).Many also chose to go live in cities and live the western values.
