From Middle English canevas, from Anglo-Norman, from Old Northern French canevas (compare Old French chanevas, chenevas) from a root derived from Latin cannabis, from Ancient Greek κάνναβις(kánnabis). Compare French canevas, resulting from a blend of the Old French and a Picard dialect word, itself from Old Northern French. Doublet of cannabis and hemp.
