Interesting you should mention phone location data not requiring a warrant. About ten years ago at work we had a problem with a student who'd posted a message somewhere that they were considering suicide. Someone else who saw this contacted the police, who came with a social worker and asked me to help find the person. (I used to work in an academic library as a porter.) The police said they had 'pinged' her phone, which allowed them to identify which corner of the building she was in. With a description, we were able to find her. So it would appear that there is already some ability to find phone locations without a warrant already.
As for the 'voluntarily shared, "subscriber information"', my understanding is that's pretty much sold to data brokers by most companies---which means the government could just buy if if they wanted. This gets back to my concern that if we tie up the hands of the government too much we end up with a situation where the government--even if it wanted to--couldn't protect us from big business. FaceBook, Twitter, Instagram, TicToc, etc---that's what really scare me, not Mark Carney. I get to vote for my government, but not Mark Zuckerberg and Elon Musk.
Also, about being affected by 'too much privacy' legislation, I disagree. I sponsored my wife as an immigrant and I can tell you that the layers of privacy nonsense that the government lays on top our interface with it can be irritating as Hell. It basically means that I cannot use the web-based system to interface with it because I use open source software. Another example, my wife has an account with the CRA but she can't access it on line because they insisted on mailing her a password through snail mail. It got lost. And to get this problem fixed, she has to contact them either through the CRA website (which she cannot access without the password) or call them on the phone number that's never answered and just kicks you off if you wait too long to get an answer. In addition, I still cannot use email to contact my doctor because of privacy rules---and I can only use the phone because the rules were waived during the COVID crisis.
There are a lot of problems with misapplied privacy rules that haven't been created or implemented with any appreciation of the opportunity costs involved. They add a huge burden on the efficiency of government programs and also the private sector when it interfaces with the government. I suspect that if the government tried to streamline the system in the way that Estonia has, it would be fought tooth and nail by people in support of privacy rights---although I think it would be just fear of change more than anything else.

I suspect a lot of the 'privacy' excuses that various agencies use to make things difficult are ultimately bogus. But that too is an opportunity cost of setting up too many rules. Saying that it isn't is something of a 'no true Scotsman' argument.
Let's just agree to disagree. I'm not particularly set in my ways about this issue, but I don't think you've convinced me yet. Luckily, the decision isn't up to me. But I still am going to use opposition to Bill C-2 as a means of introducing the points I want to raise in the second article on this subject--which I am convinced are important.
As an aside, I just want to mention how civil this conversation has been. It reinforces my feeling that there's no need for social media to be so damn divisive--it's just that the private sector systems are designed to encourage outrage and fear. Yeah Lemmy! Yeah Fediverse!
