I received the test invite too. I got a call yesterday from MP's office that CIC has notified them about my test invitation. So as I had mentioned earlier, CIC did respond within 10 business days (in 5-6 days) as the MP's office has mentioned. Those who are still waiting suggest you folks to reach out to your local MP if you haven't done so. It may or maynot help, but it doesn't hurt either. So goodluck to everyone waiting.
Test invite - yesterday 06 Nov
Test date - 27th Nov - scarborough 8.20 AM.
My ECAS is also updated, but no email from CIC. In ECAS, they have mentioned they have sent by mail, so seems like regular mail. will wait till next week.
Congrats!
