I think there are two elements to your question. One is the infrastructure. Let me tackle that one first.
I think you'll find that private companies like Encana and others are building the infrastructure to support natural gas for transportation. We recently opened up a Strathmore compressed natural gas station in September. Industry is making those strategic investments to the tune of millions of dollars.
Would they participate with transit authorities in terms of looking at providing natural gas and so forth? Again, that would be a relationship with the transit authorities and the municipalities, and I think that would occur.
In terms of looking at switching over the capital side and incentive, one of the things I can tell you is that the incentives in the U.S. are significant, both for municipalities switching over to transit with natural gas and also for passenger vehicles--and, I might add, home refuelling. If you have natural gas coming to your barbecue, there are some states that have incentives for you to adopt home refuelling to wean yourself off gasoline or diesel.
Those are happening south of the border. In front of Congress now, as you may or may not know, the natural gas bill is being supported both by Democrats and by Republicans. That will provide further incentives. There have been tremendous incentives by the federal government in the U.S. for municipal authorities to switch over to natural gas, mainly from the Clean Air Act--emissions and so forth. So there has been a role for the federal government.
I think there is a role for the Canadian federal government in that area.
