Noah Webster is usually credited with creating American spellings that have fewer letters than British spellings such as color and flavor, and canceled is the recommended spelling in a Webster's 1898 dictionary, but this Ngram appears to show that canceled only overtook cancelled in American books in the early 1980s.
