We don't include various scenarios as to what happens to Canadian oil production. We looked at the Canadian Energy Regulator's scenarios for oil production in the country and we based it on that.
It's quite possible that lower oil production would lead to significantly different scenarios for pipeline utilization, but given how the tolling framework currently works, even if it were to be lower utilization, it would mean—given that tolling systems guarantee a certain level of return—that tolling would just go higher to ensure there's a minimum return to the pipeline operator.
There are a lot of moving targets, and for that reason it's very difficult to assess exactly how much a buyer would be willing to put up. It depends on their view of longer-term climate policies in Canada and the importance, or not, put on the oil sands sector in Canada. Various actors and potential buyers will have different perspectives as to the future direction of the oil and gas sector in the country and climate policies.
