First, let me correct you and say that Encana is a producer of natural gas. To the end that natural gas is available for your barbecues and so forth, it may actually come from Encana.
From that perspective, we think there should be some competition in the marketplace with what's there right now. Natural gas has been deployed in the past. The federal government has been looking at incentives over the past 20 years and so forth. So there is a track record of trying to get an industry to adopt certain kinds of initiatives for particular reasons.
I think one of the drivers, if I might, is environmental, but another is looking at how to lessen the cost on public transit to make it more affordable. It may be through having cheaper fuel alternatives.
