I'm also from HK. My PCC has been delivered on 17 July but apparently it is not opened by the officer till today (just called IRCC) due to covid. Suggest you to call IRCC to check your status on eligibility and criminality. Security check only started once they open the PCC.
Hi Christy, thanks for your input. I'll definitely contact them to get an update. A staff of the courier I used said all parcels sent to IRCC's Nova Scotia office are outsourced to another company for delivery as a bulk. I am expecting further delays given the sheer amount of mail...
