Unbroken view alternatively seen in canal country (8)
I believe the answer is:
panorama
'unbroken view' is the definition.
(I've seen this before)
'alternatively seen in canal country' is the wordplay.
'alternatively' becomes 'or'.
'seen in' means one lot of letters goes inside another.
'canal country' becomes 'panama' (I've seen this in another clue).
'or' put inside 'panama' is 'PANORAMA'.
(Other definitions for panorama that I've seen before include "Scene, vista" , "Wide view - TV programme" , "'Vista, view (8)'" , "Unbroken view of surrounding area" , "Impressive view" .)
