That's a very interesting question. The notion of a smart city, to be honest, is still being defined. Things like the smart cities challenge, for instance, are going to help evolve the definition of a smart city and help push technology and some of those use cases to help us understand what's really important.
On a global scale, we have cities that are connected. We'd have to talk a bit about the definition of a smart city. If you take a look at Stratford, Ontario, for instance, they have installed a wireless network throughout their city, and they're looking at testing autonomous vehicles there and leveraging that connectivity to extend into smart city scenarios.
As another example, if you take a look at the city of Ottawa, all of the traffic lights are connected. I've had meetings with the City of Ottawa to see how we can extend that to enable smarter scenarios, where we can have traffic lights talk to emergency vehicles and potentially to private vehicles and pedestrians.
In terms of ranking, I don't think I have a good answer for you, because there are a number of initiatives that are going on. Some are publicly funded; some are not publicly funded. I would say that we have tremendous potential in Canada, and I think this is where we need some collaboration and some focus on specific goals pertaining to smart city to rally academia, private industry, and government around some specific deliverables.
