The Supreme Court of Canada has already tried to make the call, arguing that we have fair dealing under the current Copyright Act, which, it argues, ought to be interpreted in a broad and liberal manner such that even copies, in certain circumstances, of full articles would be seen as fair dealing.
In the United States they have an even broader approach of fair use, which sometimes allows for even more. The problem I think we see is that technology, and sometimes the law supporting that technology, trumps even some of those very basic rights.
So even if we could agree that copying a song for personal purposes is covered by the private copying levy already, so that's already being compensated, if we're talking about movies, someone who, for the purposes of parody or education or a range of different things, might want to copy a portion of a DVD—I think it's pretty clear—ought to be entitled to do that. I think the Supreme Court of Canada would agree, and my fear is that technology is taking away those rights.
The prospect of these WIPO treaties will further take those rights away such that someone who seeks to exercise those rights might well find themselves subject to copyright infringement. Teachers who want to take a segment for something might well find themselves violating the law if they try to educate their students in that fashion.
