I'm in the same boat as you. AOR2 received about two weeks ago, file received by local VO on 17 Jan (or somewhere near that date) and no medical request yet. Seems as though they check other things first before requesting medicals, which probably makes sense as the medicals can expire and I assume they want to give enough time. We thought that my fiance would be in Canada by now, but she decided to wait until my PR app is complete. In our app we said that we would like to move in January 2019, but we obviously did not expect to wait 3 months for AOR etc. Hope it wont affect our application, we just gave a moving date that was obviously too optimistic. Express Entry and skilled workers get PR in less than 6 months, yet family takes longer. Ironic eh...
