Obviously, when an access request is received, the ATIP office doesn't know everything that's in the department. So it relies on a centre of expertise to tell them. They have a general knowledge, obviously--the department--and they know where they should be looking, and they will go to these centres and ask them if they have such a document. Obviously, the people who are in charge of a certain area would have more particular knowledge, and then they would provide an answer to the ATIP office. That's how it would proceed, and the ATIP office would typically take that answer and then have a discussion with that unit, have a discussion with other units in the department, and then decide if it has information that's relevant to the request.
