Guys, you can send the results if you want, but I would recommend not to as they strictly mention NOT to send any documents unless they request.
FYI, I did upfront medical and just kept quiet, waiting for CIC to send me the medical request. But in the end, I didn't have to do anything, my Dr. uploaded my medical results in the eMedical systems and medical bureau and CIC was somehow able to track that I already did my medical. So they just updated my status on ECAS saying that my medical results have been received.
