My situation is also same. Sent application in 10th May via Canada Post Xpress post and expected delivery date was 13 May. It's showing out for delivery since 13 May morning. Tried reaching out to Canada Post but got the same response of ircc being a high volume receiver and out for delivery is the last scan that they can do. They say it's delivered to the PO box but I am just not getting the confidence..
Any ideas about contacting Ircc about this ?
Exactly same situation here for me, Sent application via Canada Post Priority and not delivered as expected at all! Instead of 1 day, it took 5 days to showing up the last status which is out for delivery since 13 May morning. I called CIC call centre this morning and they confirmed the High Volume Receiver situation. She said "Give it more time and don't send second package until one week prior the deadline." I hope that we will see the Ecas updated soon!
