Many aircraft have been adapted to act as water bombers - world war two bombers and many of the deHavilland STOL aircraft - but none are as effective as the CL-215 and it's variants in this role; these aircraft are in use worldwide and, though without an official name, have been dubbed the "Superscooper."
The 215 - and it's modernized decendants the 215T and 415 - join the CL-84 Dynavert and CL-41 Tutor as aircraft designed and built entirely by Canadair.
