I suggest calling the office where the medical was done to see if they can send a copy. I don't believe that CIC will give you a copy.
*Edit: I think that someone else said that they sent a letter with the TRV app explaining that they had already done the PR medical and asking CIC to check the e-Medical system for the medical.
Here is the thread http://www.canadavisa.com/canada-immigration-discussion-board/trv-for-spouse-after-pr-application-islamabad-medical-needed-t157172.0.html
The person requested CIC use the PR app medical for the TRV and CIC accepted that.
Thanks but I couldn't care less about football lol. My British partner is actually cheering for Germany or Mexico because those are the teams he has in his World Cup pool lol. He was secretly happy when England was eliminated because a person he doesn't like had them in the pool.
