In Ontario, member pulls up personal record (6)
I believe the answer is:
memoir
'personal record' is the definition.
(I've seen this in another clue)
'in ontario member pulls up' is the wordplay.
'in' indicates a hidden word.
'pulls up' is a reversal indicator (I've seen 'pulled up' mean this).
'riomem' can be found hidden inside 'ontario member'.
'riomem' back-to-front is 'MEMOIR'.
(Other definitions for memoir that I've seen before include "Written account of events in one's life" , "Written record of personal experiences" , "Biographical sketch" , "Written account of events one has lived through" , "Personal life story" .)
