First, I think the only example we have of trying to do it right now is in B.C., and the B.C. legislation was modelled on the federal CEAA, so there was certainly an effort in the background of that to make them work together.
I would agree with you that, in legal terms, there are some problems because the whole nature of this is that each level of government has some things that are more exclusive, if I could put it that way, and some things are concurrent. The problem with environment is that numerous things are concurrent, but some things are exclusive. How do you deal with exclusive on a substitution? That's very difficult to work through.
On the other hand, to take your model, I think federal-provincial co-operation is the proven path on this and should be the path we go forward with. In that respect, I support where this bill is, but I support where, in fact, we were with EARPGO in the 1980s and CEAA 1992. All of them had a model favouring co-operation and not substitution, and the courts in the late 1980s, when they were quite active about this, also had a fairly strong interest in seeing co-operation and not unilateralism.
That's where I would be on that.
