Presidential candidate addresses Canadian voters

CBC News reports that Ralph Nader has released an open letter (pdf) to Canadian voters advising them not to vote for the Conservative party. Nader points to US failures in the "pay-or-die model" of health care and the concentration of power in the hands of corportations, advising Canadians not to elect the party that would favour implementing similar policies in their country. On a side note, does anyone know whether Canada Firsts is any good?
