Mine is at Winnipeg office as well. Didn't find many people from there on this forum. Last I called them up was on November 26th and was told that background check is in progress. My AOR is 12th June 2018 so it is exactly 6 months today.
Even I am in this boat since AOR i.e 12th June and no updates ever since. My Background check status shows "We are processing your background check........" from sometime between june 12 and june 23. No updates after that. I am inland FSW.
