Hello,
You have to send an email to BC PNP regarding your application with providing file no or call on BC PNP helpline no, they will update you about your application status.
Might be they sent the decision to your mail address but you haven't received that.
Actually one of my friend applied for BC PNP and he mentioned wrong postal code on the application so the delivery company return back the application on BC PNP office. Make sure did you mentioned the correct address on the application.
If you get any update regarding your PNP application please update on this forum so the other people knows about decision time.
Thank you
