htaccess rules for .com and .ca

In removing the htaccess file in my last reply, this was testing a CI version that was installed in a subdirectory using only a single controller. While this worked, our original problem remains.

So, is it possible to modify htaccess to allow .COM and .CA access to a CodeIgniter page? Currently .COM access works but .CA yields a "Forbidden" error.
