Bad analogy. If you were doing what you said, but instead of taking notes, you were using a camera, you’d quickly get a visit from the UW Special Constable Service who’d probably transfer you to WRPS.
EDIT: Even if you were just taking notes on people, it’s possible you’d experience the same process.
I’m not familiar with Canadian law, but in the States, I can film someone without their permission in public. I can’t do certain things with that recording, but I can record them. In this case, I see it as just that. Recording, doing some instant analysis, recording non identifying metadata, and forgetting the recording.
That would make it gdpr compliant, at least.
People would be able to see you filming and maybe decide not to use that machine
