Ok so when you received your golden email you might have got a letter which you would have signed and sent back, did you? So the thing now is that IRCC don't have anything to do with your medical concerns. So now you will get a call from your provincial doctor, will be asked basic questions and a meeting will be fixed. You have to attend that. All the tests like sputum, blood works, skin test will be done and depending upon results you will have to take medicine for 6 months. So now wait for province to call you.
