You know that Canada (and the EU) has a worse track record... Can you provide a link to support this rather bold assertion? I am fairly familiar with Canadian law and strongly disagree with your statement.
I have had to deal with Human Rights Commissions in two provinces over the course of 10 years and have never seen anything like what is referenced: HRCs do not have the capacity to access email and documents without the owner of such being informed. Your argument is just an attempt at changing the topic at hand. The orginal comment ended with "when it comes to this" thus referencing warrantless access to email and such.
I'm not saying that the US is strictly better than Canada in the rights department. However, it's definitely not strictly worse.
