Yes it's DM because it says your application is approvedAfter the second stage of approval... you mean you got a decision made letter already? Or what do you mean by "after the second stage of approval"?
If you got a DM letter, then, it all depends on your location. Montreal and Etobicoke are the busiest/slowest offices to give landing appointments. But 8 weeks is about the maximum to get the landing appointment letter, so If you got your DM letter 2 months ago, I would recommend to call CIC.
Thanks though
