Toronto commissioned Google to make one neighborhood a "smart city". Privacy expert Ann Cavoukian resigned from the project, saying she hoped it would be a "smart city of privacy", but in fact it is becoming a "smart city of surveillance".

A data base of personal data, once collected will be misused. So the only way to make a "smart city" respect privacy is to make it not collect personal data about where people go, what they do, and who they communicate with.

If instead the project aims to "protect" the personal data, it has already gone astray.
