Yes. The basic issue is this: the federal government has jurisdiction over copyrights; the provinces have jurisdiction over things like contracts and property rights and devices.
As long as this legislation tracks the traditional contours of copyrights, there is not likely going to be a major problem. The problem is if this legislation does not link anti-circumvention liability to acts of copyright infringement, it goes beyond the traditional contours of copyrights. There is a risk that it will be invalidated constitutionally, and we would very likely see a challenge.
Just to elaborate on my earlier comment, I would suggest that the committee might want to decrease the likelihood of problems following a challenge. On the educational issues, you can decrease the likelihood of major problems by codifying these fairness factors.
On the anti-circumvention provisions, you can significantly decrease the likelihood of constitutional problems simply by linking liability for circumvention to copyright and copyright infringement.
