The system was a relatively simple one, even though it always seems complicated when I explain it.
The approach was multi-faceted, so I will try to provide a context. Some appointments to an advisory board are made by ministers, within their department, but that is not what we are talking about.
Some appointments are put forward to the governor in council by ministers, in other words, they are submitted to cabinet, and are approved by the governor in council.
Each department has a process to provide ministers with lists of qualified individuals. There is a practice among a growing number of departments to make a selection according to certain criteria and standards that are related to the qualifications of the individuals.
The word "appointment" has a different connotation in English and in French. The order is the instrument that is used to allow these people to begin serving in their position, and it is the ministers' responsibility. There are also, however, key appointments, for example, the CEOs of crown corporations, the presidents, and people who hold the higher-ranking positions. The Privy Council Office is responsible for the selection process for those individuals.
