This is just a guess, but even though there is only one TP (Both Reserve and Regular Force take the same course) the backlog in Reg Force officers awaiting BIOC is so large that the chances are probably very slim. This also indicates that the Instructional Staff will likely be very selective whom they graduate.
Hem, it`s more the other way around, i.e. RegF go on the Reserve one. George is right: the wait is LONG in Kingston. So long, trade`s closed. As a reservist, truth is, you'll get qualified much faster.
