Thank you. I'd like to thank our guests for being here today.
I'd just like to make the point that something not being new technology doesn't necessarily make it bad technology. I really appreciate the testimony that you've provided today, because if you've followed our hearings thus far, we've been getting more information about the use of propane, natural gas, and the like. So I find it very fascinating to have your testimony today.
Mr. Carignan, I'd like to understand this a little better. I do appreciate that STM is responsible for the Island of Montréal, the bus systems, and you seem to be responsible for everything.
