Mr. Chair, perhaps I'll open and then turn the floor over to my colleague, Mr. Orr.
Routine files are those in which we have a complete application, all documents have been submitted and there are no further verifications required. It's all very straightforward. What we call non-routine may be where there are documents missing and we have to go back and forth with an applicant. Also we may have to verify the status, particularly on issues of trying to establish residence. Sometimes that takes a longer period of time. Also, in some cases, some of the documents themselves may raise integrity concerns. We have to make sure that the integrity of the system is always maintained, so we may have to follow up to make sure that the document integrity is, in fact, there.
I will turn to my colleague, Mr. Orr. I think he can explain it a bit more fully.
