I could be wrong, but I don't think that's actually the case. This impaired driving law is the only circumstance I can think of off the top of my head where police can supersede your charter rights(maybe some other terrorism law as well?). In the event of an anonymous drug house call, the police can go knock on the door, but not much else unless invited in. They would still need a warrant to just walk in and search the place. With impaired driving none of this seems to apply. Anonymous call that you were driving erratically and they can just show up and demand a breath sample, despite the fact there was never even any reasonable suspicion to assume you had been drinking in the first place, or that a positive sample gives no indication whether you had been impaired at time of the report or not.This quote is hidden because you are ignoring this member.
