Canada
Montreal, Québec, Gatineau, Sherbrooke and the Quebec government have adopted CC BY 4.0 International for their open data.
Canada has developed the Government of Canada Open Data License Agreement for their open data portal website Government of Canada Open Data Pilot Project. While not a Creative Commons license it would seem that this is heavily inspired by the Creative Commons philosophy and has many similar aspects. The license includes sections on 1.0 Definitions; 2.0 Intellectual Property Rights; 3.0 License Grant; 4.0 Acknowledgement of Source; 5.0 No Warranty and no Liability; and 6.0 Effective Date and Termination.
The license permits individuals or commercial interests to use, reproduce, or add value to government data provided they use the required attribution and that they do not imply any warranty to, nor make any claim of exclusive rights to the data.
This has similarities to the Open Government Licence for public sector information used in the United Kingdom as seen farther down this list.
