Atlantic Provinces bordering right rural idyll (7)
I believe the answer is:
arcadia
'rural idyll' is the definition.
(I've seen this before)
'atlantic provinces bordering right' is the wordplay.
I cannot really see how this works, but
'right' could be 'ar' (I've seen this in other clues) and 'ar' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for arcadia that I've seen before include "part of Greece" , "Idealised pastoral setting - Greek region" , "pastoral paradise" , "ideal place in the country" , "In Greece, its capital is Tripoli" .)
