To install this beautiful shiny new version from scratch visit the download section to the right on the homepage and grab a copy. Then follow the directions in the “Read Me” file.
If you already have WordPress installed (Pre 3.3), then you can use the automatic upgrade link to upgrade to the US English version of 3.3.
Once you have 3.3 then add the wp-contents/languages folder and its contents to your site, and in your wp-config.php file change wplang to en_CA. Also the version of Twenty Ten and Twenty Eleven that is included in the download contains the Canadian English language files. That’s it, you’re done.
