Still no change, tomorrow is anniversary of date application received (September 27, 2017). Last time we called the call centre, they said we should wait until the 28th to call - is that right? It seems like September 27, 2018 should be the date when processing exceeded 12 months (take January 1, 2017 to December 31, 2017, that's a full 12 months, and January 1, 2018 would be start of 13th month, so anniversary date should be start of 13th month).
Also called MP's office to find out what they need for us to make an inquiry through them. They said it usually takes a few days for them to get a response from CIC.
No sign of any issue or problem in the file - it just looks like they just stopped processing it. ATIP notes show criminality check passed, exam and interview results are missing (she passed them on April 10, 2018), no prohibitions check done.
