Under REACH, the European Chemicals Agency or member states could do it. Under CEPA, it's essentially done within the safe environments directorate at Health Canada, or the science and risk assessment directorate at Environment Canada.
The other point to add to this is that when REACH identifies a substance of very high concern, we do mandatory surveys to see if we need to look at that substance in Canada also. We look at whether we have already surveyed it or do we have to.
