Hey CrazyLucy. That is true what they said, the OWP doesn't just go based on your passport expiry but as well if they think it will take a good while to finish or not. This is good news for you.
You have nothing to worry about with the landing interview. Your relationship status doesn't matter as they have already approved of your relationship. The landing interview usually only takes about 10-20 minutes. They will look over your PR card picture to make sure the dimensions are right, get you and your sponsor to look over the documents to make sure the information is correct, they will ask you a few simple questions, you will both have to sign something, they will usually tell you both about your rights and obligations, then you are done. They will then send off for your PR card and you wait for it to come in the mail. Nothing stressful at all.
And some local offices will let you get your permanent SIN that day in the same building. Good luck. Let us know when you get a date.
