Yes. The problem is that you have these applicants who were accepted, and they were accepted under the old criteria. These are no longer the criteria you would want to use to pick the workers who are most suitable for the types of employment currently being offered. There are annual absorption issues. Because of the size of the backlog, you haven't been able to bring them in on a timely basis. So the workers, the immigrants, are employed in their own countries for much longer periods of time. Studies have shown that overseas work experience is totally discounted in the Canadian labour market. These workers in the queue would have been evaluated under criteria that are no longer considered appropriate, and they would be much older than they were when they were considered appropriate for coming to Canada. You would expect that they would significantly underperform immigrants who are selected today based on more appropriate criteria.
