Pagers get used for PII, and if somebody thinks it doesn't happen, they're simply confident that their experience is representative. It happens, and quite frequently, in Canada.
Yeah what you linked me to talks about I believe the same case another user already linked to. It was more correct for me to say I was speaking more about the Ontario, Canada healthcare system as that is the one I work within. The healthcare systems are mostly run at the provincial level so it can be hard to talk about the countries healthcare as a whole as it can often vary province to province.
