Late update, but I've been thoroughly enjoying this time lately.

I received my PR card on March 27th (check my signature for the complete timeline).
I don't have access to my GC key, and I didn't apply for my PR card separately, so I don't know when it was sent out. However, the card was printed on March 20th and I received a GU in my tracker on March 26th.
The next day, I received an alert on the Canada Post app that a letter labelled "CANADIAN BANK NOTE COMPANY" was on its way to me, and it was delivered the same day (March 27th).
This has been an unforgettable quest, but it certainly does not finish here. I need to apply for Spousal PR for my wife, which will take another 700 years.
Thank you to everyone who helped and shared their personal experiences. I wish you all the best.
Ciao!
