Very quickly, Mr. Chair, there is a very high attrition rate among this staff. They're at relatively low classifications, and the work, as you can imagine, is highly labour intensive. People tend to move on quickly, so there is a very high attrition rate.
We are fully confident that, as the need for these staff abates as the backlog is dealt with, natural attrition will bring the numbers back to a proper equilibrium. Our experience is that there is about a 30% annual attrition rate with the staff working on this project, which frankly has been part of the issue. It has intensified greatly the need to train new staff as we're processing this backlog, so that is the answer.
