Thank you for all of the info!
I am applying to American Schools, as I live in the United States. I was quite thrilled to find out that I am Metis. I have worked with Native American communities in the South Western United States, but I had no idea I was of aboriginal descent myself. I am contacting each school i am applying to, to see what they say about claiming native ancestry on their application. I will report back what I find.
Thanks again!
