I wrote the letter as well. Sharing my template here:

Dear Minister Mendicino,
My name is [NAME]. I’m writing to you as an Express Entry (Federal Skilled Worker) applicant for Permanent Residence here in Canada. My family and I have been residing in [CITY] on a Temporary Resident Visa (TRV). I was invited to work for [ACTIVITY]. During that initial period, we decided to stay in Canada for the long term and applied for a Permanent Residence to secure our status in the country.
However, our experience with CIC has let us down, and I want to shed some light on the current situation with the applicants like me who’ve submitted their applications from Jan-Mar 2020. We’ve been patiently waiting for the immigration officers to go through our applications, but it’s been silent for more than nine months now. We haven’t received an update of any sort either. However, we’ve got to see applicants from July to September get their files processed while we continue to stay in the immigration limbo. With everything that has been going on worldwide, we’re stressed due to our temporary status. [SITUATION] and our TRV will expire this Summer. We, of course, would like to get a response before the due date. That way, we could prepare ourselves for a possible departure if our application would be refused or not processed at that time.
Thank you for your understanding and the work you do.
Sincerely,
[NAME]
