I will start, and my colleagues can add to my answer if they want.
When it comes to medical expertise, we carry out assessments, establish diagnoses and provide treatments. Those who come before the board are people who do not necessarily agree with the assessment or the diagnosis that has been made either by Canadian Forces physicians or by Veterans Affairs physicians who carry out assessments, or by our OSI clinic practitioners.
If we also provided medical expertise, we would be in a conflict of interest, in the sense that we would disagree with the veteran. In those cases, people have to obtain expertise from outside the Canadian Forces and Veterans Affairs Canada. They rely on the expertise from the Canadian health system.
The department provides veterans with legal assistance, but it does not provide them with medical assistance, as the same physicians would be involved and would find themselves in a conflict of interest situation because they were supposed to establish diagnoses, but not also testify on their clients' behalf.
There is probably a lack of expert resources. No one can force a psychiatrist, a specialist, to provide expertise. We are aware of this problematic situation. It is a difficult one.
