I would have to get you the numbers on that. I do know that over the last decade, we nearly doubled our proven reserves of natural gas in the country. That's fairly tremendous, given that we've been producing gas for over 100 years in Canada. Similarly, in the United States they've doubled their proven reserves in the last 10 years.
As to the quantum of the reserves, I would have to get you those numbers. I believe the latest estimates from Natural Resources Canada point to a 300-year supply in Canada.
