That's a great question.
We are bringing in diluent from the west coast. As well, it's coming in from the U.S. Some of what comes into the U.S. is likely imported into the U.S. and then is flowing through a diluent pipeline into Canada. It is a challenge, a structural challenge. The tanks it might stored in may be commingled with different products. There's quite an accounting of what tariff is paid on what diluent and where it comes out of the tank. There are some complexities on top of....
You're absolutely right. If the diluent is sourced out of the U.S., it would be treated differently than if it came from a country covered by the TPP.
