End under canvas? (6)
I believe the answer is:
intent
This clue is a double definition.
'end' is the first definition.
(intent is a kind of end)
'under canvas?' is the second definition.
(I've seen this in other clues)
(Other definitions for intent that I've seen before include "Resolved; purpose" , "set" , "Eager" , "Firm - plan - steadfast - purpose" , "7 Purpose; fixed (upon)" .)
