In fact, I have been an order in council appointee since 1995. I have been appointed seven times. It's about half and half, Conservatives and Liberals.
I've never had any political activity. I've never held a card of any party. I jokingly say to people that I don't necessarily vote the same way each time there is an election.
I don't think there is anything impeding my objectivity vis-à-vis political parties.
