taffy, in the last notes I ordered, on page 29 it shows that my file left Mississauga on the 3rd of November and it arrived in London on the 12th of November. My In Process date in ECAS is November 12th, so I presume that London received your application on November 7th.
Can you look for the text PAPER FILE HISTORY in your notes, for me the section starts on page 28. The entries will be sorted newest to oldest so go to the end. The last one should be an in transit note going from Mississauga to London, and the one before the last should say Office: London and Location: Registry.
Looking at my notes under eligibility, security and criminality they all say Due Date: 2015/10/31, is that what you mean by bring forward date taffy?
