Nope, haven't received medical request yet. I called IRCC multiple times and was told the application is in progress. I also received an email from IRCC saying "Regarding your case status enquiry, please rest assured your family member’s application is in queue for processing as per regular procedures. We will inform you if any further information is required. "
When I received the eligibility of sponsor letter, it said "You have met the requirements for eligibility as a sponsor. Accordingly, the Application for Permanent Residence for your relative will be forwarded to Montreal Immigration for further processing. This office was selected based on your relative’s home address and the requirements of the Immigration and Refugee Protection Act" however, the agent told me that the file is being processes in 2 offices (Mississauga and Montreal) so not sure what to believe. All my communication is coming from Mississauga office.
