I don't necessarily think that further and further delays would be a result of that, because part of the proposal would be that each institution subject to the act have strict timelines to respond to access requests. The areas in which additional funding is required are due to each institution's having to have infrastructure sufficient to answer to access requests, and it's difficult to predict how many requests each institution is going to get.
For example, the CBC, when they first became subject to the act, thought they would get a certain number of requests every month, and they ended up getting a large number of requests very quickly.
Various institutions receive a varying volume of requests. Citizenship and Immigration receives more than half of the total amount of requests, around 34,000 requests. Most of the smaller institutions receive very few requests. My office receives maybe about 100 requests a year.
