I want to explore some of the other population groups a bit. I think you mentioned a couple of them, Dr. Sareen. You mentioned refugees and first nations. I want to start with indigenous people.
I have done some reading about, of course, the residential school experience, which was a period in Canadian history where I think we had trauma on people on a mass scale. I want to get your thoughts on the prevalence of PTSD in the indigenous population, and whether you think it's a significant issue that we should be looking to incorporate into this framework.
