I do not know Toronto well enough (never been there) to come up with questions about the colour and size of your recycling bins but what I would do is put the data in context (what Tim Berners-Lee calls Linked Data): If you start an article on, say, recycling bins (e.g. in an educational wiki environment, so that others can join in with their experience), all sorts of questions will spring up: What is the best size, colour scheme, or collection schedule? What is the history of garbage collection in Toronto and elsewhere, and how does it relate to the programming concept of the same name? Or, a bit more abstract, is the traveling salesman problem an adequate description of the traveling garbageman problem?

Each of these topics will require some sort of data to be incorporated, and those from Toronto could be used to get things started, thereby propagating the message that Toronto is opening up and possibly inciting others to follow. Once they chip in (say, from Singapore or Umeå), it will also become possible to put the Toronto data in perspective — how do their respective ecological footprints, PISA scores and other characteristics compare?
