Well, as nice it would be to bust all those people curtrently stealing artists' material for free right now, I think it is way too broadly worded to have a hope of getting through. Of course, we are talking about the Harper Conservatives, so you never know. ha ha ha.
The proposed law would exempt programs from seeking the computer users permission to install software for:
$1:
a program that is installed by or on behalf of a person to prevent, detect, investigate, or terminate activities that the person reasonably believes (i) present a risk or threatens the security, privacy, or unauthorized or fraudulent use, of a computer system, telecommunications facility, or network, or (ii) involves the contravention of any law of Canada, of a province or municipality of Canada or of a foreign state;
I don't see how you could pass a law that, by reference, requires conformance with all foreign laws.
I have a feeling hat the days of people stealing songs and movies wiht impunity are just about done though, regardless. Great news for artists.
