They still have not given a time line for Mexico to open. I got this yesterday from Mexico :IRCC wedsite show that a lot of VAC’s around the world are beginning to re open. Since yesterday it was updated.
The documents you have submitted have been added to the file, and the file is in queue for the assessing officer to review again to determine if the interview is necessary. However, conditions in Mexico have not improved, and we are still unable to return to the office to assess paper applications, including Permanent Resident applications. Once we are able to return to the office, the assessing officer will review your file again. Thank you for your continued patience and understanding.
