No. They have posted the competition. It was in the Canada Gazette, and those interested can apply, and presumably have applied. But I'm not aware of the process itself. The application has to be sent to PCO, to the senior appointments secretariat. But the process was carried out as it would be for any other job that is posted in the paper. If you believe you meet the qualifications, apply at such and such a place by such and such a date.
On October 3rd, 2006. See this statement in context.
