In Canada you can hold a Recreational Pilot's Permit and enjoy the privileges on a 'Declaration' medical. You take the form to a TC designated doctor and sign it in front of him. My local guy charges half a Class 3 medical fee. As I am over 60 I also have to have an ECG.
This does at least give the doctor a chance to ask about your health and have a look at you to see if you can actually stand up and walk without bumping into things.
When we emigrated we had to have a medical. The doctor who did it was so decrepit we actually had to help him stand up and find the baby in wife's arms. Seemed rather deaf as well so using the stethescope was probably a bit pointless. We chose him because we didn't have to wait for the appointment!
