late 15c., "basket," from Latin canistrum "wicker basket" for bread, fruit, flowers, etc., from Greek kanystron "basket made from reed," from kanna (see cane (n.)). It came to mean "metal receptacle" (1711) through influence of can (n.). As short for canister shot, it is attested from 1801, so called for its casing.
