Only a CFS agent can renew a QFI category as it's strictly a military qualififaction.
There is no such thing as a 'panel' examiner to renew a FI rating. If you need to renew at PPL level, you will have to attend a seminar (only ones I know of are in the UK) AND fly a check with a FIE. Did you mean revalidate or renew? If you mean revalidate then you can do the 2 out of 3 requirements of experience, seminar and flight check.
