Bill C-22 (Canada, 2026) updates laws to give police and security agencies faster and clearer access to digital data during investigations. It expands authorities to obtain subscriber information, transmission data, and tracking data from telecom and online service providers and from foreign companies. The bill also creates a framework requiring electronic service providers to support access requests.

Notably, a single secret warrant authorized the surveillance of everyone on the Verizon network:

I know those are about the US and this law is Canada, but the same things can happen.
