Generating wealth is not easy. You have to encourage people to do so.
As a comparison, if I had put 25 smartphones in a room even before they had been put on the market, you would not have known what they were. Perhaps you would have looked at them, but you would not have known how to get them to work, nor what they might be useful for. You would not have used them.
It's more or less the same thing with open data. People don't really know how to use it. You have to get them to do so. We had to convince one CEGEP after another to develop applications. Today, they understand the usefulness of these applications and they appreciate them.
Citizens who use these applications are also happy. The applications do not yet officially generate wealth, but one way to make sure they are sustainable is to get young people to create businesses for that very purpose. These applications will allow people, for instance, to find a parking spot without risking a $45 parking ticket. People will gladly pay $1, $1.50 or $2 for an application from an application store. If there was a way to help people easily find out what is available in the area so they can have an even nicer evening without paying much more, by accessing an application store, that would be a way of creating wealth. We have to find ways to do this.
There are other data, for instance, on contaminated land on which there has been drilling activity. These lands are located in municipalities and provinces; the federal government also is responsible for contaminated sites. It is possible to transform this information into open data so that people who have to work on a given piece of land, regardless of whether the land belongs to a level of government or a business, can find out what others have already paid for the drilling.
