Generally speaking, I agree with you that many institutions react first by redacting documents instead of trying to give the most information possible through access to information. The Access to Information Act includes exceptions and they must be applied correctly. We often note that these exemptions are discretionary in nature. We note that institutions tend to use their discretionary power not to grant more information, but instead to block it quickly, rather than grant it.
Within the framework of our investigations, we try to work with institutions so that information is made accessible or not redacted any further. In certain cases, redaction is reasonable; in others, we realize that, if more information were granted, people would better understand decisions made. In contrast, hiding information often creates confusion and raises questions.
Certainly, the more information is made available, the more confidence there will be.
