Ok....
when you go in for your "medical" the physicians assistant will administer several tests including an eye exam, hearing ,pee in a cup, you strip down and walk around a bit...etc. He/she will ask you a series of medical history questions, you answer these questions truthfully. From that your medical is sent to Borden or wherever it goes. To the best of my knowledge the CF not access your medical history from some health Canada database. If so I sure didn't sign that release. You definitely don't bring your history with you to the review. There are loads of threads going into much more detail on this matter.
Cool?
