I'll start. I don't know of any specific study looking at the north and lack of access to drugs. Certainly there are a lack of resources in the north. That doesn't include medications only, but also lack of psychological services. It includes lack of health care teams in the community. That's understandable. They are isolated communities and there aren't the same resources as there are in the city. When people have fewer resources, they certainly tend to do less well.
I also used to work in Yellowknife on a part-time basis, as a consultant psychiatrist. The federal government paid a lot of money to sometimes transport people to Yellowknife to be assessed by me and to be seen, but really that access isn't there for everybody. It's very difficult for people to get a lot of the services they need.
I can't speak specifically to a lack of access to drugs. I'm really not aware of the entire scenario there, but I know their services are less and they can experience more difficulties as a result.
