Thank you, Mr. Chair.
Good morning gentlemen. Thank you for being with us today to share your expertise. After listening to you, and a number of other witnesses in the past few weeks, I get the sense that this is going to cost me a fortune, that my car is totally obsolete and I that I should just choose another technology. Let's hope we get there and it's for the better.
My first questions are for Mr. Clark, of the Canada Post Corporation.
You seem to have quite an extensive experimental lab. Why have you focused more on propane than on natural gas, given your experience and testing?
