Canada

Wasn't there something like this already? Swear I read couple months ago something about a police force buying data off data brokers to get around protections in place.

Rights are about being compelled to do something, mostly by the government.

In theory, if a business tells you that they're going to share your IP address and you don't like it, you can take your business elsewhere. In practice it's not that simple, of course. There are too many huge companies who have monopolies or near monopolies, restricting your choice. They also often don't disclose what they're doing with your data. Also, often when they ask for consent, the consent is buried in some 400 page click-wrap agreement that you can't realistically be expected to read before agreeing to.

Canada needs better privacy laws. Currently Europe is leading the way there, but Canada's more aligned with the US, where corporate influence is much stronger.

Thats why police were signing up to info IP purchase vias ISP and other vendors so they could purchase suspects data outside of the warrant system

They'll still have all the information. They just need a warrant if they want to admit they have the information. Computers are fundamentally insecure by design. Unless there is some sort of major overhaul in the basic structure of computing technology, we need to be a LOT more cautious about how we integrate computer technology into any sort of potentially sensitive area.

It flows that your IP is now PII, and will be subject to regulation. We'll see when the first lawsuit happens.
