I don't believe any of what you're saying but if you feel your Doctor would do that, I'd suggest you find a new doctor. Perhaps a psychiatrist would be a good place to start.
Your Doctor can undoubtedly access the test results if you have OHIP pay for the lab work. If you chose to pay out of your own pocket, I don't believe they're there for him to find, but may be available if they do some weird search specifically to find it, and I have trouble imagining anyone giving a fuck about that. To suggest otherwise, implies some grand conspiracy to find your clap test, which just seems very strange to me. I assume that those of you are all concerned about this are concerned that your Doctor is going to go out of their way to uncover the tests, and then show themm to who, your wife? But why would they do that? You're sounding a touch paranoid. But if you feel this way, there's always the good old Hassle_Free Clinic.
Anyway, I'm not going to debate this with you. But if you're using that as an excuse not to get tested, then that's a whole other concern. And consider this... What's the greater concern, that your doctor conspires to out you to your spouse, or you giving your wife an STI? Good luck explaining that!
