North American city to change or not? (7)
I believe the answer is:
toronto
'north american city' is the definition.
(I've seen this before)
'to change or not?' is the wordplay.
'change' is an anagram indicator.
'or'+'not'='ornot'
'ornot' is an anagram of 'ronto'.
'to'+'ronto'='TORONTO'
(Other definitions for toronto that I've seen before include "Transatlantic city" , "Ontario's capital" , "Canadian city" , "Ontarian capital" , "Second city of Canada" .)
