Is your office charging any fees? Are you recovering any revenue to do the services you are doing?
Again, in the case of the City of Mississauga, there is a fee to file an ATIP request, and depending on how many copies the response is, there could be a photocopying charge, etc., so that the agency being requested of this information isn't out of pocket.
Currently, you are not charging any fees at all associated with the services your office is providing on a cost-recovery basis.
