(Needless to say, a mark must include a design anyway, you can't register a trademark for a simple "word")
Not true. From the US Patent and Trademark Office's Basic Facts About Trademarks (section ``Depiction of the Mark''):
    To apply to register a mark comprised of word(s), letter(s), and/or number(s), with no particular stylization or design element included in the mark, you should select the "typed" drawing format.
But, for all I know, Canadian patents might be different.
