Zero. Thank you for that.
Mr. Clark, I'm tempted to get into a very large conversation about the state of the global economy and its impacts on Canada as a trading nation. Let me zoom in on energy prices for a moment, something that occupies Ms. Cook's world as well.
As the federal government prepares its budget this year—and this is what we're engaged in right now—from what you're seeing of the global energy perspective, what would be a prudent price for Canada to assume for oil going ahead through this year and into the next? You made a number of allusions to IMF studies and the like. What would be prudent for Canada, and what is the impact on the Canadian treasury if we get the price wrong, if we overestimate the value of what we're going to get from our oil products?
