The example I gave was the City of Toronto, and they did experience a 50% reduction in the number of requests. The comment I would make is that the resources that organizations have to commit to access to information, to the formal request process, while most of them may have staff who are dedicated to that--and my colleagues can comment--the commitment of resources does go far beyond that. For example, normally the information that needs to be retrieved does not sit with the FOI office; it sits with finance or parks and recreation or another arm of the ministry. It involves a lot of people whose main job is not access to information.
Then I did mention the role of our office in an appeal. So individuals put in a request, get a response, aren't satisfied, and they have the right to appeal to their provincial access to information commissioner, or federally. That, again, involves time and resources that I would suggest could be better spent elsewhere.
