I'll kick it off.
I'll make a couple of comments here, and I suppose these are very much matters of opinion. Competitiveness is a relative concept, and I think you alluded to that. If your cost structure is going up and so is your competitor's, then on balance it should not make a difference. It depends a lot, though, on where you are and what your capital structure looks like. If you have a lot of old, inefficient capital, then you're going to take more of a hit in the face from rapidly changing costs.
Going back to Canada in the 1980s, when we protected ourselves briefly from the effects of rising energy costs, I think most analysts going back and looking at that would say it wasn't a good thing. We didn't win as a consequence of that; we delayed the adjustment process we needed to go through.
Clearly, we want to avoid things that create an imbalance so that our costs become higher than our competitors . We're not in that position now, and we need to keep pushing on that. The last thing we should do is protect ourselves from underlying global fundamentals.
