I wouldn't let them within 100 miles of Toronto. The fundamental issue here is one of self-governance and self-determination. I just don't believe that any business—not Google, not anybody—should be in the business of operating our public spaces and our civic infrastructure. There is a limit to what you can do with a public-private partnership, and that is way over the line.
There is an experiment going on in Barcelona, I believe, in a smart city project where the community and the citizens own the data. That will be a very interesting thing to watch.
The observation I would make is that I am still cautious about the gathering of the data in the first place. I believe that the underlying issues relative to surveillance create too many temptations for people. At the moment, it's way, way too difficult to monitor what they're doing with the data once it's collected. I believe that all of these things require, to use an old government phrase, dramatically more study before we move forward.
