How Canada or the Canadian government wishes to do it is really up to you.
I would add that under the Australian government legislation, the ombudsman can only be removed with cause. Most ombudsmen who have been appointed over the years, both at the federal level and the state level, have been very much people of integrity. They have been widely seen that way by the community and have generally enjoyed bipartisan support across the political spectrum. The Australian experience is that it would be unlikely that the government, at either the provincial or state level or the federal level, would appoint somebody to an ombudsman position if they wouldn't be seen to have the necessary integrity to be accepted in a bipartisan fashion.
