Let me comment on natural gas, for starters.
There is a pretty substantial east-west infrastructure in place right now, and in fact it has been in place for decades now. There are pipeline systems that extend from Alberta and western Canada—and you could extend that back to British Columbia, because of the interconnected nature of the pipeline systems--to eastern Canadian markets, including Quebec. In the natural gas sector there has been a pretty substantial infrastructure put in place.
I think on the oil side there has been as well. A lot of western Canadian oil is transported east, not only to Canada but to markets in the U.S. midwest and beyond. At least in those two sectors there has been a pretty sizeable west-east infrastructure put in place.
