That's an excellent point, actually. It's a separate constitutional issue the extent to which any copyright reforms may affect the right to freedom of expression.
Numerous Canadian academics have published on this subject, and I would recommend that the committee take their advice seriously. I'm thinking particularly of the work of Professor Carys Craig at Osgoode Hall Law School, the work of Professor Reynolds at Dalhousie, and the work of Jane Bailey, my colleague at the University of Ottawa.
These are all very relevant concerns. Without more specific context, I'd be reluctant to give you a legal opinion, or even an opinion in general, about whether or not this is a worry. But I can say that in my review of the extensive literature on technological protection measures, this is one of the most frequently cited concerns with strict anti-circumvention provisions: the potential to stifle free expression.
