City borders of Toronto still in the wrong place (7)
I believe the answer is:
ectopic
'wrong place' is the definition.
The definition suggests an adjective which matches the answer.
'city borders of toronto still' is the wordplay.
'city' becomes 'EC' (the City of London postcode).
'borders of' suggests removing the centre.
'still' becomes 'pic' (short for picture).
'toronto' with its centre taken out is 'to'.
'ec'+'to'+'pic'='ECTOPIC'
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for ectopic that I've seen before include "In an abnormal position" , "unusual pregnancy" , "In an unusual situation" , "out of place" .)
