I'm not too proud to admit when I'm wrong, but I'm only partially wrong.
While it appears that traditional sharing of copyrighted works is legal in Canada is legal now (This is going to be hell if it holds up, soon you will see copys of Microsoft's source codes, and corporate documents being shared on kazaa)
Here is your mistake:
"The mere fact of placing a copy on a shared directory in a computer where that copy can be accessed via a P2P service does not amount to distribution," Finckenstein wrote. "Before it constitutes distribution, there must be a positive act by the owner of the shared directory, such as sending out the copies or advertising that they are available for copying."
Basically they are saying that sharing in its current sense isn't illegal, but actively violating copyright laws is. This is a very fine line, and I'm willing to bet another judge will overrule the previous decision and rule that placing files in a designated folder for download constitutes intent.
