The Ontario government are acting like autocrats. Usually because they are trying to hide their own sins.

No functional government keeps secrets from the public unless they are incompetent and/or corrupt. There is no third reason.

So they either were asleep at the wheel or someone was receiving kickbacks to allow this to happen, and with changes to access to information, it will be harder, but not impossible for outsiders to dig up the truth.

But it is not impossible.
