Thank you, Mr. Chair.
I would like to thank all the witnesses. Unfortunately, we don't have time to look at the question in depth, but I would like to thank you for being available.
I'll start with Mr. Boag.
In the Natural Resources Canada document, I see that the refinery margin is clearly higher to the west of the Ottawa River. We're talking about refineries in Toronto, Calgary and Vancouver, compared to those in the east. The Canadian Renewable Fuels Association's document provides an explanation and says that the situation was caused by excess refining capacity over demand.
Is that the only factor for explaining the clearly higher margin in the west than in the east? Are there any other factors?
