No I did not mention anything to that extent, I just showed recent visit to China as a personal travel in travel and address history that they have asked for. If you have re-entered in China just for PCC , it is a personal travel only for a personal purpose.
Meical check was done in my home country after I entered India, just do it like couple of weeks before you are ready to submit your final docs, depending on how much time it will take to reach Canadian high commission in your country. In India you have to get medical checkup done in specified hospitals only and the result is sent to Canadian high commission within 3 working days from the day of your test.In lieu of it they give a acknowledgement of the test and you have to upload that along with the final docs.
I did not understand the background check part?? are you referring to check done by local police before issuing PCC in my home country?? If yes then afcourse it had to be done before they issue me PCC here in India.
The background check I meant. Did CIC already ask for your PCC from China and you have submitted them without any issue at all ??
