In Australia, because there's a range of investigation agencies, anti-corruption bodies or the police or the auditor general or the ombudsman, the primary responsibility of the oversight agency is to ensure that those protection systems are working rather than necessarily conducting all of the investigations. There should be a separation between investigation and protection, because there's a potential conflict of interest. If you've investigated something and found no wrongdoing, it's then very hard to carry through and ensure that person is protected.
In Australia, we're still sorting it out. There isn't a perfect model yet, but at least there's a clear recognition that there needs to be that separation. There's a range of investigative agencies that are part of the scheme. It doesn't just all fall to the one, putting all the eggs in one basket, which seems to be the concept in Canada.
