why do canadians spell certain words with a U but americans don't

I don't know the answer to this but my friends and I have discussed it. In England English, we use the U. The American language as I know it is called "American English". We couldn't figure it out but it became a joke that "Americans don't like YOU (u)" lol

Because that is how it is spelled in Canada. To spell colour, color, is just being lazy.

I think it is because of the strong French origins in our dialect.

That is because when an american goes "on about", they go for a walk or a talk...when a canadian goes "on about", their going canoeing.

but the reason it's officially spelled with a "u" is because Canada still (at least somewhat) falls under Great Britain, and the "u" in the spelling comes from British English. Canada uses the metric system for the same reason.

Canadians held onto their British affiliations much longer than the Americans. The u addition is the original English spelling. Due to the cultural imperialism of the United States, American spellings have inflitrated the English language. I guess we parted ways in politics as well as spelling.
