I have sent an email to CSS.ClientCheck@gov.ab.ca
And also called the supervisor in the Edmonton office (the number was provided by @bdidol ), she said its not her office where this request would go but she took my phone number and said she will try to find out which department/office it would have gone and she will give me contact information from that departments (hopefully she could find that department).
I’ll share the details as soon as I get any email or call back from that supervisor.
It is unfortunate that we are having to go through this. In my case, I got the social services department in Ontario to resend the response to IRCC. The 2nd response was sent to IRCC almost a month ago and my file still hasn't moved. So in my case, IRCC has received response from social services twice yet I am still awaiting DM on sponsor side.
