Many cities, some countries, are moving towards open data.  Edmonton is leading in Canada http://data.edmonton.ca/, Calgary is getting started https://cityonline.calgary.ca/Pages/Home.aspx?redirect=/cityonline.  Canada has a pilot project http://www.data.gc.ca/default.asp?lang=En&n=F9B7A1E3-1 that is not very active or exciting or marketed yet.

The UK http://data.gov.uk/ and Australia http://data.gov.au/ seem to be leading.
