I'm not sure how to answer the question, because I've heard a lot of different versions about what a strategic EA would be. In the absence of some better definitions, should it be legislated? Well, I guess in order to legislate it, you'd have to define what it is.
I don't know if legislation is the best way to go at that question, because I think that's an evolving situation. I'd be loath to see some sorts of strictures put on it that may or may not be appropriate.
I think it's important that there be a distinction between what project-specific reviews do, even to the extent as they must incorporate cumulative impact assessment to keep them conceptually separate from what I understand a strategic-level review to be.
Let me give you an example. Suppose we had done a strategic review at the outset of what would be involved in developing the oil sands in Alberta--it was never done--and on a project-specific basis you're going at it piecemeal. Can the same kind of panel deal with a project review as can deal with a strategic-level review? I rather doubt it.
Who should pay for it? If you're doing a strategic-level review, you can't ask individual proponents to pay for that. That's far beyond what they ought to be paying for.
So I think there are very significant problems here that would need to be addressed. I can only suggest what they are rather than provide a solution at this point.
