In the example you provided, the medical record would not include any information about the patient, or the individual in your example who was in the accident, suffering back pain. We would not know—nor would the definition we propose for work product cover anything that would identify the patient, or the accident victim in that particular case.
What we are talking about, to use an example that many witnesses have provided to the committee, are things like documents, memoranda, opinions, and correspondence that are authored by people as they function as employees or professionals in an organization. It wouldn't include personal information about somebody, like their medical condition, religious beliefs, or something removed from that, reflecting, “I went on a call report to try to sell my company's clients a widget. I came back and wrote a report for my manager about that encounter and how many widgets they wanted to buy, and how many they didn't want to buy.” We're talking about that report as a work product of the salesperson who wrote it. That's the type of information we are proposing should be explicitly excluded as a work product in PIPEDA.
