I'm Canadian. That means I'm supposed to use the English spelling. However, I tend to use mostly American spelling. There are some words, however, that the American's just spell wrong laugh (cheque v. check) so for those words, I use the English spelling.

My main reason for using the American spelling is a practical one. For some reason, my spell checker doesn't want to work for English English. And since I can't spell without it... <sigh>
