AFAIK (Canadian here) it's legal to use anything commercial if it's for educational purposes, so they'd have to prove you're profiting off of it (with current laws) to prosecute. Please someone correct me if I'm mistaken ...
I doubt it's that clear-cut; if I'm downloading episodes of Glee or recently released movies to watch on my laptop, I'm not exactly using them for educational reasons, but I'm also not making a profit.
