As a fellow Calgarian, I can tell you that it's one of the things that I personally have been watching to try to understand why it's not moving forward.
In a rail sector, there is a different dialogue, compared to that of buses. There's a different kind of procurement at play.
In general, what I can say is the following. When it comes to zero-emissions technologies, for certain the public transit fleet, whether it's buses, coaches or trains, is a gateway to heavy-duty freights and trucks, so there's a benefit there. Even if it is bureaucratically challenging to get it out the door, it does move the industry pretty quickly.
When it comes to public transit, particularly technology-intense, complex transit projects, it is fair to say—and to be fair to our transit agencies in our cities—that they are not well equipped for this transition, to start with, which is why it becomes stuck in a bureaucratic quagmire, to some extent. I'll give you one example. Calgary Transit, Edmonton Transit, TTC, and OC Transpo are great transit agencies that do great work, but they have not, historically, had large cadres of electrical engineers, hydrogen engineers or high-power systems engineers, whose job is to innovate this stuff.
