Get on a governing body (5)

I believe the answer is:

board

I believe this clue is a double definition.

'get on' is the first definition.
(eg boarding a train)

'a governing body' is the second definition.
(I've seen this in another clue)

(Other definitions for board that I've seen before include "Get on (ship)" , "Directors' group" , "Plank" , "Collection of directors" , "See 21 Down" .)

I've seen this clue in The Globe and Mail.
