I will suggest you call IRCC and talk to an agent. For all you know by now CBSA may have reverted back to IRCC with your recommendation but a less than diligent VO may be slow to update your file.
See below a thread shared by someone else in 2019 on this forum to understand the process better:

Just for sharing, I received CSIS note today and I found that they received CBSA request for security screening on 26 June and their recommendation was sent to CBSA on 20 October. From this now I understand how my security check process and timeline :
1) Security check start (initiated) : 20 March 2019
2) VO Agent write in the note that application send for CSS on 27 May 2019
3) Security screening start and process by CBSA on 26 June 2019
4) CSIS received request from CBSA for security screening on 26 June 2019
5) CSIS complete the security screening and sent their recommendation to CBSA on 20 October 2019
6) On 24 October I called IRCC and kind agent told me that IRCC received from CBSA before two days so I guess CBSA send their recommendation to IRCC on 22 October 2019 ( I’m still waiting for CBSA note to be sure)
7 ) I received re-medical check request on 20 November 2019 ( I guess my security check was done on 19 or 20 November )
From this timeline my security took 8 months to complete but my comprehensive security screening was only 3 months and 25 days . As you can see most time was because of VO so I believe VO behavior is matter
