Parliamentary Press Gallery shuts down blogger?

An interesting article by blogger Stephen Taylor (Who calls himself a "Conservative Party of Canada Pundit") about a recent event on parliament hill where the legacy media outlets seem to have abused security to have this blogger removed.

If security on the Hill is the responsibility of the Speaker, and if I have been granted access to most non-privileged areas of the Hill by the Speaker, what authority does an official of the PPG have in calling in the guard to have me removed from perhaps the most public area of the Hill?
