Shop is past moving to lake (10)
I believe the answer is:
patisserie
'shop' is the definition.
(I know that Patisserie is a type of bakery)
'is past moving to lake' is the wordplay.
'moving' indicates anagramming the letters.
'to lake' becomes 'erie' (Lake Erie is one of the Canadian/US 'Great Lakes').
'is'+'past'='ispast'
'ispast' is an anagram of 'patiss'.
'patiss'+'erie'='PATISSERIE'
(Other definitions for patisserie that I've seen before include "eclairs and the like" , "Its cakes are fancy" , "store for Brownies?" , "supplier of tarts" , "where cakes are sold" .)
