I look every day on CIC log in and ECAS for updates. DM was done either this morning or maybe yesterday afternoon on ECAS, so it's something I just saw.
I guess then it's a bit backwards for me. The last thing that happened was a week ago they requested proof that I was living and working in Canada (when I applied to Sponsor my wife I was living outside of Canada), so I e-mailed it to them right away.
Then 2 days ago they sent me an e-mail saying they received it and nothing else was needed from me, and now this morning I see that status changed to DM, but I have not received PPR yet. Hoping they are able to send it by close of business day or else it's just more waiting.
