I don't know what conditions are applied. I think use is restricted. However, open government advocates would tell you that they want the data to be out there and then they can show you what they can do with it once they have the ability to manipulate the data and reuse it and re-mash it and make different applications with it. But I don't know the conditions Statistics Canada applies to it.
