I believe the author is referring a slight difference between Canadian and American copyright law. Someone explained it to me like this:

I can come over to your house, give you a CD, tell you how to put my CD in your drive, rip it, and burn your own copy. That's legal, in part due to the levies on recordable media in Canada (which go to the artists, though none of that money has ever been distributed; that's another story).

I can't, however, make a copy for you. Weird, but true, from my understanding.

So - the question in Canada is: under which of these two scenarios does P2P filesharing fall? Apparently, the downloading is not illegal, but the sharing is illegal.
