Not so much, because if they're federal reserve lands, clearly the provincial laws don't apply unless they're of general application. But if they're specific to reserve lands, they wouldn't apply. Obviously, the Department of Fisheries...if that would apply, that would apply as well. So it's not so much overlap; they're the only agency doing the regulatory work on behalf of oil and gas first nations.
Being that it is a complex world, there's always overlap somewhere, but it's not necessarily in conflict.
