They should send it to the address you specified at landing - unless your lawyer filled out forms with you at your landing?
If it was "mailed" October 28th it may not have actually been put into the mailbox until the 29th and maybe not processed until the 30th. And 3-4 days in the same city, sure - but across Canada maybe a week.
Ok, Thank you. I will contact via phone. However, I heard some others mentioned that they changed their address online. I wonder whether they referred the PR application status page or some other page relevant to the PR card delivery.
