Mrs. Thi Lac, cost is primarily affected by the complexity of each case. Recently, we closed a file that had been open for four years. It involved the revision of 15,000 pages, all subject to section 15 of the national defence and public safety legislation. It's extremely difficult to assess cost when we're dealing with this type of file. That is why, in terms of the cost of an investigation, I hesitate to quote you a figure.
If a department is uncooperative and takes a long time providing us with the documents, or if I am forced to get a subpoena to get the documents, the cost increases. Given the complexity of the cases, it is difficult for me to give you an exact figure.
