What I can do is perhaps give you some current numbers.
If you look at the entire oil and gas industry in Canada--this is everything from the producers through to the service through to the pipeliners--that contribution is in the order of $165 billion, or 12.1% of Canada's GDP, and that was in 2006. In 2006 in Canada we generated or produced something approaching 17 billion cubic feet a day, and something approaching 1.75 million barrels a day of crude.
I'm not sure I can relate that to an uplift number. Actually I think that's all I can say about that. I'm not sure I can answer that one.
