We study the canonical flavor enhancement arising from exact conservation of
strangeness, and charm flavor. Both the theoretical motivation, and the
practical consequences are explored. We argue using qualitative theoretical
arguments and quantitative evaluation, that this proposal to reevaluate
strangeness signature of quark--gluon plasma is not able to explain the
majority of available experimental results.Comment: 14 pages including 6 figures, submitted to Journal of Physics G
