It turns out that Bill C-27: The Electronic Commerce Protection Act covers a lot more than just anti-spam. It was written to include a requirement that software cannot be installed on a user's computer without consent, as an anti-spyware provision.
What a good idea.
No one has the right to put software on my computer without MY permission. Just as no one has the right to put software on YOUR computer without YOUR permission. It is, after all, YOUR computer. You bought it to do what you wanted or needed it to do. Why should anyone have the right to put things on your computer? It isn't THEIR computer.
Unfortunately some very dangerous last minute changes have been tabled.
