Waterproof canvas-like fabric (9)

I believe the answer is:

tarpaulin

(Other definitions for tarpaulin that I've seen before include "canvas given treatment?" , "waterproof material" , "protective headgear" , "Waterproof canvas used as covering" , "Heavy waterproof canvas" .)

I've seen this clue in The Telegraph.
