I think that might have been a question Mr. Garneau came up with on his own. I didn't mention anything about U.S. initiatives to try to bar Canadian oil or dirty oil. That is a concern. It may be targeted at Canadian oil sands oil or any oil from Canada. We've tried to point out to the Americans that our oil, on a full cycle of greenhouse gas emissions basis, is no dirtier than oil that comes from Venezuela or Mexico or even parts of California. As I understand it, that potential legislation is being pushed a little bit more by California than by some of the other states. I think Californians need to look at the oil they are accessing in their own backyard before blaming others for any oil they might see as being not up to the standards they would like to have.
I think it would be an unworkable regulation, since once oil leaves the ground and is put into a pipeline, it's fungible. It's mixed in with oil that comes from all sorts of sources. It would be pretty hard to segregate oil that comes from one area, such as the oil sands, from oil that comes from an area near Edmonton, for example, which is light and is a lot cleaner.
