In July there were reports of a proposed motion to open up the City of Calgary's data. In particular the motion says:
Identification of opportunities to make more of The City’s data open and accessible while respecting privacy and security concerns , and ensuring that data is available through use of open standards, interfaces and formats
At time of writing it is not clear whether any datasets have been made available yet.
As one commentator points out, the motion does not explicitly mention licensing:
Calgary - Public Data Catalogue. No author.
