Could be your CFAT results are not as competitive as others, despite meeting the minimum. Maybe your interview was not as strong as they had hoped. Maybe your TSD-PI results were borderline,. or less than optimal. Basically what CFRC HQ was telling you is that while you meet the minimum threshold to apply for the job, there are other more competitive candidates, and if you wish to continue with applying for this particular trade, you may have a long wait aheaad of you. You could always call them back and see if there are any trades for which you are more competitive and if they interest you.
