Congratulations, you're done. Your cic account won't update until you land. You will receive (if you did not get them already) SA and AIP letters (letters saying you meet the eligibility, one to the sponsor, one to the principal applicant). Those letters are usually sent the same day or the next day you see changes on ECAS. The DM letter is very unreliably sent, sometimes right away, sometimes with very long delays, sometimes not at all. But the DM letter is not what you are really waiting for now, you are waiting for the landing invitation letter. It might still take a few weeks, but you will officially become a PR soon!
