Received my certificate today. Unfortunately, it was bent in the mailbox, and no attempt was made to deliver it in person, although I was home today all day. But I don't blame Canada Post because in no where on the envelope it says "Do Not Bend" as other stated, and it was a regular mail. I blame IRCC for using regular mail, and not express with a signature required to make sure it's delivered in person. Anyway, the bend has left a small line in the middle, and once I took it out, it was semi flat. I think it's not a big deal.

With this, I am officially done with IRCC. It was a very long ride. Now off to the passport application. Thank you everyone again for your help and support here, and wish you all good luck with your citizenship applications in the next steps, and I hope things will start to move faster for you
