A Dictionary of Canadianisms on Historical Principles (DCHP) is available in a 1967 edition (Avis et al. 1967) and in a 2017 expanded, updated and partially revised edition (Dollinger and Fee 2017). DCHP is a historical usage dictionary of words, expressions, or meanings which are native to Canada or which are distinctively characteristic of Canadian usage though not necessarily exclusive to Canada. The first edition was edited by Walter S. Avis (ed.-in-chief), C. Crate, P. Drysdale, D. Leechman, M. H. Scargill, C. J. Lovell, and published in 1967 by W. J. Gage Limited.
