I don't think that is true. I think what's important to keep in mind is that by the time these pipelines.... If they were to be deemed to be in the public interest, what you're going to be seeing overseas is a significant development of brand new technology, so just as we have a number of upgrades under way in our own refineries today, and current and new technology is at least compatible with Canadian standards.
I believe that when we're looking at Canadian public interest, particularly on global issues such as air quality and climate change, we need to understand the energy system on a global level. That would be something that over the course of the next six to seven years I think you'd see considerable gains in with new installations.
