Has anybody received response from CIC after they filed their 2020 tax returns? I got a temporary file number that starts with the XF. CIC Requested to submit my 2020's tax return. I did a month ago. I haven't heard from them after that. I can't even check the status on-line because the file number is temporary. Do you know how long it will take to hear from them with a parmanent number? Thank you.
