with Crown Corporations, Canadians do have the option not to use or support them, however it's not in Canadians best interests not to support Crown Corporations, because Crown Corporations have monopolies on entire industries, Crown Corporation monopolies are so powerful that their private sector competitors in most instances refuse to compete with them, instead competitors of crown corporations instead tend to focus on a small niche that a Crown Corporation cannot penetrate. UPS competes with a crown Corporation Canada Post by offering something Canada Post can't offer which is 48-hour international shipping, UPS in Canada doesn't bother trying to be competitive with Canada Posts domestic mail, as it knows new legislation or a new regulation will stop them from being competitive.
