Doctor on tour including city in Canada (7)
I believe the answer is:
toronto
'city in canada' is the definition.
(I've seen this before)
'doctor on tour including' is the wordplay.
'including' indicates a hidden word.
'TORONTO' can be found hidden inside 'doctor on tour'.
(Other definitions for toronto that I've seen before include "major city" , "Capital city of Ontario" , "Provincial capital" , "Ontario's capital" , "Second city of Canada" .)
