Finally got PPR today! ECAS status changed to Decision Made in the morning, and got PPR email at night.
Here is my timeline (Ontario Master PNP Stream):
Aug 24, 2015 Received by CIC
Nov 19, 2015 File Number
Apr 1, 2016 Upfront Medical Exam
Apr 14, 2016 Medical Exam received by CIC
Oct 5, 2016 Ask for additional document (Master Degree Field of Study, publication, supervisor name, resume)
Jan 25, 2017 Update my wife's passport as the old one will expire this year
Mar 10, 2017 PPR
I have called CIC several times since January and asked MP twice (the most recent visit is this Monday), but every time the reply is security check in progress and no deadline can be provided, so it's kind of surprise to suddenly receive PPR today.
Best Wishes to everybody who is still waiting! It's such a long and frustrating process, but we will eventually get there.
