Hi Tristan and Arash,

another possible simple solution is to copy and paste the "english.el" style 
file from your


directory into the one with your own style files, defined in TeX-style-local, 
which for me is


and rename it there to "canadian.el". Of course you can also edit it to create 
your own canadian style file. I did something similar for the "british.el" 

Is that correct, people?

By the way, I noticed that emacs's own lisp/language directory already contains 
an "english.el". Does someone know if there's any path conflict with the auctex
