I will speak to SISIP because I can; it's my mandate. There is a very clear historical reason that we have had approximately 90% take-up on vocational rehabilitation. Of the many people who would be releasing, some of those 10% will be people who plan to retire. From their perspective, if they're 53 or 50 or 47—pick an age—they're clearly at the latter half of their career, and not 23. They may choose not to do the vocational rehabilitation, and take the income support knowing that in a few years they will be retired and the pension will be adjusted. That's the vast majority.
The second case for why people do not take vocational rehabilitation under SISIP is they're physiologically, either because of their psychosocial...or their abilities, unable to do so. An important nuance is that the veterans rehabilitation program for Veterans Affairs is not just vocational. It includes psychosocial and medical. There's a way that you would obviously not do vocational, but you would be doing medical rehabilitation that would qualify you for the veteran earnings loss benefit that wouldn't apply with SISIP.
