I suggest that it's a foundation for our growth and is likely to remain very important.
How much more or less important it becomes, I really couldn't say. What I do know is that we are still in a development phase, in countries such as China or India, where growth itself, which is high, is fairly commodity-intensive, unlike growth in our own economy, which is less so. This means that as a result we get a leveraged effect of higher growth: one more dollar's worth of growth in China has a disproportionate impact upon us, through that commodity effect—either through the price or as a result of the volume itself.
It will fuel Canada's growth as far out as you and I can see. There's lots of untapped potential in Canada.
