Yes, I sent an email to the Canadian embassy on Feb 7, asking if they could provide an update regarding the PCC. They sent me an email on Feb 25, saying the following:
“This is to acknowledge receipt of the Mexican Police Certificate results. These will be uploaded directly into your application.
For the moment, no further action is required on your part.
Our office will contact you should we require additional documents or information.
Thank you for your patience and for keeping your correspondence to a minimum.
Regards | Cordialement,
Immigration section | Section d'immigration
Embassy of Canada, Mexico | Ambassade du Canada, Mexico”
In total, it took around 70 business days, or just a little over 3 months, for the certificate to be uploaded.
