I don't know what role the Copyright Board of Canada could play in digital file sharing. However, what I do know is that, when a person purchases a digital book covered by acquisition rules, they subscribe to a license, in a way, or a method of use. You can read those rules, which cover about 22 pages, when you purchase a book through iBooks or another application. No one actually reads them, but in reality, the buyer commits to doing something. If they share the book's content, in violation of the rules they accepted, they are committing an illegal action.
How to prevent people from taking those kinds of illegal actions? In my opinion, that is the state's responsibility. Someone, somewhere, must ensure that the rules are being followed. As I was saying earlier, we have tried to talk to the RCMP people, here in Montreal, whose offices are located in Westmount, on Dorchester Boulevard, I think, but they are unable to resolve that situation. So it is really a problem.
All you have to do is go on Facebook to see the number of Quebec books, French-Canadian books, that are available for free, without any kind of potential revenue for the creators and copyright owners.
