Sure. My application was received on Nov 3 last year, and I got AIP on Oct 2, DM on ECAS on Oct3, I never got an actual DM letter.
I got my landing letter in MAIL, and it's issued on Oct.16 ( I didn't check my mailbox until yesterday because CIC agent told me they will NOT MAIL to me, only E-mail or through CIC acccount..well guess what, it came in mail....) and asked me to go to the interview on Oct 30th, so about two weeks after.
CIC agent said it normally takes the Kitchener office 3 weeks to send out the landing letter once the case is been referred to them (I assumed that means DM cuz that's the impression the agent gave me), so if you have passed that 3-week time, 1)check your MAILbox, and if you still didn't get it; 2) call CIC and the agent can send a note to the IRCC Kitchener to remind them you've been waiting for over the 3 week period
Good Luck
