You can check ECAS or MyCIC (the latter more comprehensive). Ask your lawyer to see if he doesn't already have access to it.
Regarding the medical exam: I sent my app in March 27, 2017, got AOR on June 9, 2017, then received the medical request on Dec 18, 2017. That's a 6 month gap between AOR and receiving my medical request, and a 3 month gap between sending the app and receiving AOR. Some people get their AOR real quick and then wait 9 months for a med request, then get PR 2 months after that. Some people get their AOR real quick, get their med request 3 months down the line, and then wait one year for a decision made. It's entirely circumstantial. Check out the link in my signature (someone else created this google sheet, very useful tool) for other people's timelines. It's also dependent on your visa office location.
