what about Canadians?

I think I like the look better with the "e", but I honesly don't remember what I was taught in school.

In general Canadian spelling follows British spelling with two major exceptions: we prefer "z" instead of "s" in words like "analyze", and we don't use the extra squished-together vowels (what are they called?) in words like "fetus" and "estivate". But we do use the extra "u" in all those "our" words like colour, tumour, honour, etc. So Canadian spelling is not entirely like either British or American, it is something all its own.
