I am going to give you some figures from September 30, 2010, because that is the most recent data we have. There were 1,177 Canadian employees working abroad. Of those, 85% met the requirements of the linguistic profile for their pool of positions, and 14.9% did not. The 14.9% was made up of non-imperative appointments, non-rotational single assignments of departmental employees and employees from other departments.
On March 22nd, 2011. See this statement in context.
