That's a good question and I want to address it.
Under the provisions of the Canadian Citizenship Act as it stands today, it's my understanding there is a process of oversight. Anyone whose citizenship is revoked presently is given a notice by the department. Then there are federal appeals, and then there is a ministerial appeal. Of course, the oversight for renunciation would be the same.
At the same time, I would also suggest that to elaborate on the procedural process of how it works, maybe it would be proper to ask some questions of the CIC officials as well.
