Explorer of Canada's coast (5)
I believe the answer is:
cabot
'explorer of canada's coast' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cabot that I've seen before include "famous explorer" , "Sebastian -, navigator" , "Italian explorer (father or son)" , "John (Giovanni) -, navigator, explored N. America" , "One of two explorers" .)
