Canuck

1825–35; perhaps ultimately to be identified with kanakaHawaiian, South Sea islander (<Hawaiian; see kanaka), if the word once identified both French Canadians and such islanders, who both were employed in the Pacific Northwest fur trade; later reanalyzed as Can(adian) + a suffix

The term Canuck is perceived as insulting when used by non-Canadians or when referring specifically to French Canadians. But among Canadians, it is sometimes used as a neutral nickname or term of self-reference.
