We've looked at this particular issue with respect to the evidence that exists, and I think you're going to have a couple of speakers presenting tomorrow who will formally present some of the literature that's available on detention in refugees.
I just worked with a resident and produced a paper that's in the process of being published in Canadian Family Physician journal. There are a number of studies that come from places like Australia, some from the States, and some from Europe, which have shown that there are mental health impacts of putting people in detention—and perhaps it's not startling. I think even under ideal circumstances, having someone who does not have the freedom to walk the streets and can't go outside does have an impact, particularly on people who have faced trauma. The extent of the duress seems to be correlated with the length of time in duration. Some interesting small studies have come out of Australia that have actually looked at people who are in the community and a similar group of people who are in detention and have found the rates of mental health issues are much higher, although the cohorts were quite similar.
Yes, I think absolutely there is a concern that we might be re-traumatizing people who have already demonstrated they are quite vulnerable.
