My wife had DM and within an hour got an invite from Kitchener. Some folks get emails within a few hours/days, and some don't get anything for a few weeks. If I was you, I'd relax for now, and just let them come to you.
Even if they send you an email, it doesn't say, "You won the PR lottery!" or "Welcome to Canada!". It just says they have finished processing and either: this office will contact you with an interview appointment, or they include the invitation to the interview in the same message. That's where your PR application "will be finalized" -- it means land.
