I'd like to ask Ms. Marsh a question.
You mentioned the competitiveness and the price differential that we're facing right now between Canadian oil and American oil, in particular. Part of that, we are told, is because we don't have pipelines to tidewater. I understand from recent events and analyses that this is shrinking.
How do you see those projections going? If we get a pipeline to tidewater, what will that price differential be? How much of that is caused by factors other than accessibility to world markets? At what price will oil drive investment in, say, new oil sands projects?
