We compared the refinery margins in the United States with those in Canada. We noted that they were practically the same. When the refinery margins increase in Canada, they increase by the same amount in the United States. All public sources are saying that right now this is a result of a gas shortage in the United States, meaning that the demand for gas in the United States is greater than the supply, which increases the margin significantly. The only way to restore balance would be to decrease the demand or increase the supply. That is what is going on right now with the gas imports from Europe.
