To add, ISED literally goes around in cars to scan for non registered BTS (or even non conforming ones) and report them, sometimes (or a lot of times) they catch false positives when the interference happens to be a strong LED lol. The gov uses the tech to ID individuals however, especially in group gatherings or around certain locations, always look around for big vans with no windows :), I either don’t take my phone or it’s always on airplane mode until I want to disable it briefly before activating it again.
