I have two points. First, it's not a case of sharing. Government doesn't share with government; government reports to Parliament. Remember that Parliament is over the government and can demand anything from government that it wants.
Second, when people are held accountable on the small things, it prevents the big things from happening. Therefore, some minor managerial problems within an institution the size of the Government of Canada are not going to bring down the government, but are going to keep it focused in ensuring good service for Canadians.
