I'm going to partly defer to....
We work closely with the Canadian Trucking Alliance, going back to the heavy side of the market here. We very much concur with their view on this, which is that we all understand that this fuel, if we're successful, will attract taxation. It has to; governments need that revenue, both federally and provincially, for infrastructure.
But the reality is that right now, of that 50¢ a litre there is also a cost structure, because this is really an infant industry. We need the benefit to get into the market. We need to get to a certain scale, and in their perspective, at least on the truck side, that's probably about a seven- to ten-year timeframe.
I think a percentage could be set in terms of percentage penetration. Is it at the 10% level, the 5% level? Where is that threshold at which you tax the fuel?
We think this will come. That said, we also think that natural gas, because it is an inherently lower-cost commodity than crude oil, has lots of capacity to carry tax. What we don't want to see, though, is killing this before it gets started.
