That's very difficult to summarize generally, because there are multiple institutions and it's changing year to year.
For example, soon after the Federal Accountability Act was passed, the Canadian government extended the law to 15 more public federal institutions, and there was suddenly a huge backlog of complaints and delays as those institutions got up and running. It's very difficult to generalize in that way.
The key thing is to remember that we are 54th or so in the world, so we're way behind in terms of ensuring an effective and timely right to know.
