An imaginary set of English spelling rules, cited from a politically-correct wish to be inclusive or out of ignorance of Canadian English. There are only three varieties of spelling in English: British, US, and Canadian (the last is often described as a combination of the first two). English spelling in all other places follows one of these conventions. At least two of these forms are prominently used in countries of the Commonwealth of Nations.
Which kind of “Commonwealth spelling” is this, British spelling or Canadian spelling?
