Based on my past experience, I got a reply from Canadian Embassy in Mexico that they have sent my PCC to Canada. I wrote an enquiry to IRCC (similar to any other case specific enquiry, related to queries) and attached that email from Canadian Embassy. IRCC replied to me almost after 1 month that they have received the PCC. So I guess they do checke emails but it just takes a lot of time for them to reply.Yes I have sent an email to Canadian embassy in Mexico, they told that they have already sent my PCC to office processing my application on February 15th, 2019. Could you please let me know how can I inform my office processing my application that they have already sent it. I could not see any email in the letter they have provided . Is there any way I can call you .
So far I have never called or spoken to anybody in IRCC/CIC. Everything works based on CSE (case specific enquiries) which they will definitely check and reply to you. But make sure there is atleast 1 or 2 weeks gap between 2 CSEs that you send, because if they see the same applicant sending multiple queries within short spans of time, they will never reply.
