Hi. My file got transferred from Ottawa VO to Sydney VO. Then I got an email saying they successfully received my document. Also I see the update in my profile "December 10, 2020 We are reviewing the additional documents you provided". So, I am exactly in the same situation.
Here is my understanding. Application got transferred from Ottawa to Sydney due to heavy workload in Ottawa. At Sydney VO, they finally started processing the additional document I submitted almost 60 days back (Canadian PCC). Hopefully, criminality check would be completed soon.
