National park in the Canadian Rockies (5)
I believe the answer is:
banff
'national park in the canadian rockies' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for banff that I've seen before include "Historic county town in Grampian" , "Town (and old county) in Aberdeenshire" , "Scottish region" , "Scots community" , "Scottish North Sea port" .)
