Oration rewritten for Canadian province (7)
I believe the answer is:
ontario
'canadian province' is the definition.
(Ontario is an example)
'oration rewritten' is the wordplay.
'rewritten' indicates anagramming the letters.
'oration' is an anagram of 'ONTARIO'.
'for' is the link.
(Other definitions for ontario that I've seen before include "Province of central Canada" , "city" , "A North American lake" , "provincial area" , "part of N America" .)
