I'll ask a question through you, Mr. Chair.
Once you've built the infrastructure, you have to maintain it, and then there's the operating cost. On this question of diesel refuelling versus natural gas, natural gas buses or trains are maintained in ways completely separate from diesel buses and trains. In the experience of the Toronto Transit Commission, which tried the natural gas buses, there was a huge amount of operating cost associated with them. Once the infrastructure is built, it needs to be maintained so that it has a state of good repair.
If the federal government starts off with the capital budget, would your research also then calculate the dollar amount needed over a 20- or 50-year life cycle for the state of good repair plus the separate operating costs in order to service the fleet? Using TTC as an example again, they rebuilt their buses. You would have to hire the people and train them to rebuild those natural gas buses. You have to maintain them to make sure they don't fall apart, or when they fall apart, you have to know how to upgrade them or fix them.
Does any of your research calculate all of that cost to show what the operating life cycle is, plus the impact it has, say, if it's a private trucking industry or a transit authority?
