I think it's probably worth taking the time to talk a little bit about the overlap with the mandate of the Attorney General in clause 26, but I'll answer your question more generally first.
There are certainly occasionally--because of the shared nature, constitutionally, of jurisdiction over environment--acts that would trigger an offence under both a federal and a provincial statute. That's not to say that the offence provisions are necessarily overlapping, but it does mean that there may be circumstances under this bill in which a citizen could be complaining to both the federal and the provincial governments, and certainly I would leave it to you to work out whether that's a problem.
